Back in the 70's ,there was a product called Kasite motor tune up... You slowly poured the product down the carburetor while reving the motor to decarbon the top end... I did that once in 75 and had the fire dept called from the neighbor behind me.., it smoked out the whole block.... Funny thing is, we didn't have any mosquitos that year... 😂
Intermittent faults are fun aren't they! I had a real head-scratcher years ago with my 1989 Pontiac Grand Prix SE (rare 5-speed car, loaded). It had a 2.8L or 2.9L V6 (I forget which). I bought it as a DEMO and got a sweet deal on it because nobody but me wanted a 5-speed car and the Sales Manager's wife had actually been driving it! So, now to the "Gremlin". When the car was a couple of years old (still in Warranty) the fun began! Sometimes when I left work, sitting at the same traffic light on the way home the car would throw a CEL! When I turned left and hit second gear it would go out. OBDI car, no code logging. It might do it once and then go away for a week, or it might throw it two days in a row. No pattern to It. I took it to the dealer, and they ran it in the bay and nothing happened. One Tech thought it was the TPS so they changed it. Nope it kept doing it! I took it back and they changed the upstream O2 sensor. Nope. Kept doing it. Now I was getting a "little anxious". I found an OBDI laptop software called Diacom. Originally developed for marine applications. So, after work every day I ran that SW on the way home and a few days later SNAP! Caught that Gremlin! What was happening was the O2 sensor would go from normal cycling to flat line, then come back when I hit second gear! I went BACK to the dealer and showed the Service Manager the data log and he said: "Son of a Bitch! We've been seeing this problem for a while and haven't figured it out! We've had several customers having it!" So, we walk back in the parts area and there was a HUGE box of those sensors, half empty! It turned out there was a "bad batch" of them and even GM hadn't figured it out! Needless to say, whenever I had to take my car to the dealer after that it got "Special Care"! I put a Bosch O2 sensor in and it was still there when I sold the car at 140,000 miles!
I had a 2004 1500 with those spider injectors, and they failed on me once. Me being me, decided to replace them myself. Pretty easy job, actually! Except one of the little red caps fell out of my hand while I was removing them, and fell straight to onto the intake manifold. I spent two days trying to get it out (should've just pulled the manifold). Finally borrowed a scope from someone at work so I could figure out which cylinder it was in, then a portable dewalt vacuum that I modded with a long and skinny flexible hose, deep into the engine, and finally got it! Yesrs later, I now feel confident enough to remove an intake and do it the right way, but ten years ago I wasn't, and we didn't have all these youtube channels teaching us how to do everything!
As one of your older mechanics here I'm sure we all observed the vintage old school ignition still hanging around - cam driven distributer type. Even though computer controlled, it has yet evolved to the current crank triggered ignition of current design. Tough chasing misfires on that setup. Especially when you have multiple contributions to the performance (the ECM/O2 sensors). Thanks for the video on this. That Suburban still has a ways to go before it's right but is on a good path now. Thanks for the Lauren/WifeUnit cameo...always nice to see your beautiful wife included. 😊
I've owned a pickup with this engine for years. I can't remember how many distributor caps I've replaced. They are notorious for shorting out where the crossed circuits burn through. But they look cool! Just another room in the engineers wing in Hell!
The spider efi on these rely on a poppet valve which can get stuck in the open or closed position, the fix was individual injectors on the revamped design which came on the 2003 Silverado/Sierra 4.3L. Injectors that don't fire fuel will cause a miss too, either check squib/pwm power or check for a physical clog
Setting the points gap in the generation before this ignition module was a pain until they started making the distributor cap with a "window" to adjust the points gap via a screw driver and dwell meter while the engine was running. That innovation lasted only a short while before electronic ignition made the old tech obsolete. Back then a tune up (points, condenser, rotor and adjust timing) was needed every 5K miles. Might want to check spark plugs and wires. Also vacuum leaks were notorious on old vehicles. If you can believe it, back in the 50's vacuum ran the windshield wipers.
Love the safety Crocs!! 😆 🤣 😂 You also need drive the vehicle for a few miles to allow the MAP sensor to give the ECU data to allow it to create/select a good fuel map for running at an optimal range.
@@scottbishop7899 the old vacuum gauge and set the timing by listening for pre-ignition at full throttle: is this suburban post timing light then? [Edit: Google AI says 2013 is the last year a strobe is used to set baseline timing -- I cant find the last year you can advance the timing past baseline, seems like my 87 you still could but not my 89, by 94 you couldn't in a Ford 5.0L]
@@ab2230 Yes but that would be new vehicles and not older ones still on the road legally, 93/94 is when the emissions changed in the UK where timing and fuelling were controlled by modules/ECUs and catalytic converters became mandatory. Older vehicles are not as stringent because they could have carbs and adjustable timing, they didn't ban these vehicles outright after the emissions laws became more stringent (for vehicles manufactured AFTER a specific date). You still have older vehicles on the road in the US that are NOT fuel injected, computer controlled timing and fitted with catalytic converter mandatorily! Ray has shown cars fitted with carbs etc, I cut my teeth on vehicles where everything but the ignition system was mechanical in nature but I was around to witness the evolution from that to small modules that only determined the fuelling and ignition and into the more comprehensive OBD and OBDII and then onto CANBUS systems of today's newer vehicles. So on classic/older cars you best know how to tune a carb or adjust the timing because the handheld diagnostic equipment isn't going to do it for you!! And it's not going to tell you what's wrong with the vehicle either lol (I know it's not as simple as the diagnostic equipment can only guide you so far in some cases before you have to pull your 'mechanic' pants up lol) Diagnostic equipment is a necessary evil these days because there are so many sensors and actuators controlling things you just wouldn't know where to start, these systems are supposed to make it easier but it's definitely not as straight forward as some might think it should be (my old boss remembered when the 4 gas analyser was a game changer, he wished the new diagnostic equipment made it fool-proof but even it can be 'fooled'/misled by faulty wiring/connections etc). Mechanics of this era need to be computer literate and auto-electricians aswell, a lot of that will change when EVs are the only vehicles on the road and that's not that far away (although they will probably be able to tell you what to do 'step by step' in a sarcastic tone of voice lol). I'm glad I'm an armchair technician these days, mechanics don't get the praise or recognition as other tradesmen do generally. A big difference between the older and newer cars is that it has become easier/cheaper to purchase a vehicle (getting credit and overall price) but more difficult/expensive to repair a vehicle in general (more expensive and just more electronics that govern specific systems and the big brain (ECU) controlling them). Tangent over ... 😆 🤣 😂
This reminds me of the first "specialty" tools anyone bought. A distributor wrench and timing light. Having a dwell meter meant you were popular in the neighborhood.
If your fuel trims can go positive and negative around 0%, then 128 makes sense. It's half of the 8-bit value of 256. So 128 is 0%, 127 and below is getting increasingly negative percentage and 129 and above is getting increasingly positive percentage.
Yeah, that’s why he said it looks maxed out. I would’ve said the same if it were 255/256, 15/16, etc. Every time you see something that’s a power of two, there’s a good chance that it’s a binary value that’s all 1s.
With a brand new ECM, it hasn't time to adjust trims yet. If you know a little about computers, standard tech would have a range of 0 - 255, not 0 - 128. Or 127.
@russellstyles5381 Not necessarily. If you use one byte to store the value, that’s 1111 1111 (BIN) = 255 (DEC) = FF (HEX), but the range isn’t necessarily 0 to max. It can easily translate to negative 128 through positive 127. One real world example is the X and Y coordinates for a Nintendo 64 thumb stick. They obviously use one byte for the X coordinate and another for the Y coordinate but this is interpreted as -127 thru +128 when translated to coordinates for the game software.
@@emmettturner9452 Aren't we both (and indeed everyone who has also chimed in) arguing the same point point here? That, for example if you had a system that went from -100% through 0 to + 100% you could very well represent this as raw 8-bit values of 0 (-100%) through 128 (0%) to 255 (+100%). Ray seemed confused as to why his fuel trim percentage was at 0% but the raw data value was 128. The above seems a perfectly reasonable way of explaining that.
A handy trick for hard to locate screws is to attach a magnet to the shaft of your driver, this will increase the magnetism of the driver so you can just put the screw on the end and put it straight in the hole, no flangies required.
Coffee does vibrate,,, on a molecular level. When heat is transferred into a material, this causes atoms to vibrate more rapidly. Therefore, hot coffee does indeed technically vibrate! So you are right!
I've driven a lot of those older trucks back when they were new. I never opened that particular cap with the ball in the disctibutor and not in the cap. All the ones I serviced had the coil in the cap and the screws were captured. They are the TBI engines.

I did change plugs once on my old Volvo 850 and also the plugs and wires on my volvo 740 once, i did them one at a time so as not to misplace them, pull one off and out, replace and put back on, the best method
Love your videos, Ray! I really enjoy how you go through your investigative and then solving process in an entertaining way. I totally agree that keeping a vehicle running longer offsets most of the resources required to make a new vehicle - except for spare parts. On the other hand, older vehicles are less efficient. I would love to see what the costs and benefits for the environment analysis from that as a long-term study. Lastly, while CO2 is processed by plants to make sugars and grow, there's no net benefit of increasing the amount of CO2 to enhance plant grow because there are other limiting factors such as access to nutrients, water, solar irradiation, etc. The problem that we have right now with climate change is that the increased concentration of CO2 in our atmosphere is helping the planet store more solar energy as heat - this has all the implications that you are probably aware of. From your videos I see that you are someone who likes talking about politics, science, etc., even if it is difficult through the RUclips format and how people will react to them. I just thought that you'd enjoy a comment from another person who likes talking about those subjects. Happy (almost) new year!
Blue Streak parts are considered the premium option by Standard, offering enhanced performance and durability compared to the regular Standard line of parts. (Blue Streak parts are manufactured in Bialystok, Poland) at a facility owned by Standard Motor Products. Standard Motor Parts used to be manufactured in Long Island NY USA but now their regular Standard Parts can be made in a variety of locations (United States, Canada, Mexico, China, and Poland).
Man, I wish I could find a dianostic mechanic in my area. Most of them around here just fire the parts cannon, realize it didn't fix the problem, and then tell you the problem is to reload the parts cannon and fire a few more volleys.
About 4 months ago while travelling, my '06 E-350 Ford cargo van. Acted much like the Chevy in video. Had younger mechanic find the same faults. Long story short, older mech tried to get me for new trans since wouldn't run while in gear (5.4. 3 valve). Trans is holding engine back and getting ready to blow up was old mech diagnostic. Young guy rechecked codes. Nothing BUT RPM monitor sensor on trans flat line with no lights/faults/ codes. .when done and leaving the old guy went verbally "Karen" on younger mechanic about screwing HIM out of $3k sale! Only hope younger guy found another job . Wising both your blood and shop families good prosperity, health and spirits for up coming year.
Good catch on the bad vacuum line, but the fuel trims will show a vacuum leak which makes it easier to pinch lines and check for effectiveness. Also surprised you did not check MAF. It should read roughly the engine size in liters at idle. I.E 5.7 Grams per second. MAFs can effect transmission performance. Cheers!
The 128 fuel trim value toward the beginning of the video is the same as 0% fuel adjustment. the ECM is an 8 bit computer which has 256 different options of 1's and 0's to make a byte. 128 is exactly half way between 0 and 256 which means that the fuel trim can be adjusted rich or lean the same amount.
Wow! Those "snake oil additives" + the foam got to work really fast. The only problem is that poor Lauren got stinky feet. A cause for the misfires could be the sparkplugs. If you haven't checked them, who's to say they won't fail again. That popping sound when you reversed was the black cap from one of the snake oil bottles. Great video, once again. I've learned some new things.
Coffee does in fact hydrate you because of the water in it. Caffeine makes one urinate more, but it usually doesn't happen to frequent coffee drinkers since your body basically becomes used to the caffeine. Of course straight water is best for hydration, but coffee shouldn't dehydrate you unless you have underlying medical conditions.
the distributor gear was common on those for wearing bad, and causing a misfire feeling while driving. I had a 97 and i changed the distributor for this, after i drove across canada, the rotor came loose inside the cap and tore it up. when i went to put the new cap on, both screw holes stripped. all i had were wood screws, so thats what i used to hold the cap down, i wasn't changing the distributor again.
I have 4 late 90's GM OBS trucks. The rotor and caps are junk. I am going to replace the caps with brass contacts. I have had good luck with the injection spiders. Easy to replace, just a couple of hours. They are strange for sure.
Coffee is so deeeelicious! Btw I bought a box of your coffee and to my lack of attention I didn't see it was the cups lol so now I have a cool box for the kitchen.
Here it is.. No carbon tip left in the rotor!.. No wonder it ran bad. I would have check the plugs too. They have been trying to run with little spark and a lotta fuel.
Had a similar issue that I chased down on my 4.3 V6. Ended up being a combination of vacuum leak at the rotten PCV elbow as well as a nasty mass air flow sensor. At least it has a new fuel pump, spider injector, plugs, wires, rotor, and distributor cap now 🤦🏻♂️.
I would have check the TPS for linearity, I had issues with one on a old 92 3.8L(with 82k miles, yup it was not daily driven) for decades with loosing power when getting on it over 3k rpm it was like dying, spark plug and wire has been replaced like 15 years ago with no difference. I mostly resealed the intake, replace a bunch of hoses, some showed sign of crack some not but they were original. I have also replaced the fuel regulator but no change. I never had check engine light(the bulb work, and Iknow pre OBDII so yeah...) when it was loosing power I kind of pumped the pedal and it make it better but not always and only had issues when engine was at temperature never when cold. I replace the O2 a 30yo sensor... clean the MAF. So I took the mulitmeter in restor mode and sure enough past 60-70% it was not going linear. I replaced the sensor and voila! problem solved. It had also a bad smell at idle when we parked it in the garage and now it gone, no more smell!

I remember when the old dist. cap screws were captured to the cap
I remember when they were two metal strips that acted as clips to hold the distributor down and inside there was a rotor, points, condenser.

Amazing! Another successful peeling of the onion of symptoms. Ray's troubleshooting is the best!
Your safety crocs are very stylish.
The 128 on the fuel trim is probably the raw digital value from 0-255. 0 means full lean and 255 is full rich, so 128 is perfectly in trim.
Good video today. Shows the little thing can make a big difference. Hope you have a great new year.

From your videos I see that you are someone who likes talking about politics, science, etc., even if it is difficult through the RUclips format and how people will react to them. I just thought that you'd enjoy a comment from another person who likes talking about those subjects.
Happy (almost) new year!
Blue Streak parts are considered the premium option by Standard, offering enhanced performance and durability compared to the regular Standard line of parts. (Blue Streak parts are manufactured in Bialystok, Poland) at a facility owned by Standard Motor Products. Standard Motor Parts used to be manufactured in Long Island NY USA but now their regular Standard Parts can be made in a variety of locations (United States, Canada, Mexico, China, and Poland).
Growing up with mechanics around me I was always taught to pull a spark plug it tells you a story of what's going on.
90th! Happy pre-new year Ray,Lauren, Dave, and Justin! Roger in Pierre South Dakota
Happy Monday Ray. Hope you and the wife are doing well.
Man, I wish I could find a dianostic mechanic in my area. Most of them around here just fire the parts cannon, realize it didn't fix the problem, and then tell you the problem is to reload the parts cannon and fire a few more volleys.
Ha ha found it hiding over here👍(Florida fog 😂😂)
About 4 months ago while travelling, my '06 E-350 Ford cargo van. Acted much like the Chevy in video. Had younger mechanic find the same faults. Long story short, older mech tried to get me for new trans since wouldn't run while in gear (5.4. 3 valve). Trans is holding engine back and getting ready to blow up was old mech diagnostic.
Young guy rechecked codes. Nothing BUT RPM monitor sensor on trans flat line with no lights/faults/ codes. .when done and leaving the old guy went verbally "Karen" on younger mechanic about screwing HIM out of $3k sale!
Only hope younger guy found another job . Wising both your blood and shop families good prosperity, health and spirits for up coming year.
Ray, you would have been a good doctor
Rechecking and rethinking is what it’s all about
Happy New Year
Should have been a astronaut😂
A Chevy with a bad ECM what a surprise I'm actually more surprised you were able to get one for that thing
Good catch on the bad vacuum line, but the fuel trims will show a vacuum leak which makes it easier to pinch lines and check for effectiveness. Also surprised you did not check MAF. It should read roughly the engine size in liters at idle. I.E 5.7 Grams per second. MAFs can effect transmission performance. Cheers!
The 128 fuel trim value toward the beginning of the video is the same as 0% fuel adjustment. the ECM is an 8 bit computer which has 256 different options of 1's and 0's to make a byte. 128 is exactly half way between 0 and 256 which means that the fuel trim can be adjusted rich or lean the same amount.
Good video and I enjoyed it. Thanks. Happy 2025.
Wow! Those "snake oil additives" + the foam got to work really fast. The only problem is that poor Lauren got stinky feet.
A cause for the misfires could be the sparkplugs. If you haven't checked them, who's to say they won't fail again. That popping sound when you reversed was the black cap from one of the snake oil bottles. Great video, once again. I've learned some new things.
You were really enjoying that V8 at the end of the video there :). Fruits of your labors.
Coffee does in fact hydrate you because of the water in it. Caffeine makes one urinate more, but it usually doesn't happen to frequent coffee drinkers since your body basically becomes used to the caffeine. Of course straight water is best for hydration, but coffee shouldn't dehydrate you unless you have underlying medical conditions.
That's a funny looking car part sitting next to those fuel system cleaner bottles
the distributor gear was common on those for wearing bad, and causing a misfire feeling while driving. I had a 97 and i changed the distributor for this, after i drove across canada, the rotor came loose inside the cap and tore it up. when i went to put the new cap on, both screw holes stripped. all i had were wood screws, so thats what i used to hold the cap down, i wasn't changing the distributor again.
I have 4 late 90's GM OBS trucks. The rotor and caps are junk. I am going to replace the caps with brass contacts. I have had good luck with the injection spiders. Easy to replace, just a couple of hours. They are strange for sure.
Happy new year
Welcoming back!
Have a great new you and family.
The old cap and rotar is what I remember easy work on and fix.
Man I love a suburban, nice smoke show lol
Reeeeee You kept shutting the door ….that’s my favorite noise 😎
Great video ray
Coffee is so deeeelicious! Btw I bought a box of your coffee and to my lack of attention I didn't see it was the cups lol so now I have a cool box for the kitchen.
I was working in parts back in the 80s. Standard Motor Products brought out the Blue Streak line out as an upgrade over OEM.
Better than a brown streak 😳🤣🤣
"No right turn" You're ok Ray you turned left.
i was yelling at the screen saying there aint no center ball in the distributor cap! lol delco....see you again in 20,000 miles
I was about to scream the same thing 🤣🤣🤣
Here it is.. No carbon tip left in the rotor!.. No wonder it ran bad. I would have check the plugs too. They have been trying to run with little spark and a lotta fuel.
How is this a day old and Im barely getting it now!??whats happening youtube?

Sitting there racing the engine was called an Italian tuneup in my youth
Surprised you did not change the plugs during the tune up. Thanks for the video.
Seat belts are good. Know what you are doing so you don't die.
This has to be one of the last GM engines with an actual distributor in it. Distributor cap reminds me of a Ford flathead V8.
Had a similar issue that I chased down on my 4.3 V6. Ended up being a combination of vacuum leak at the rotten PCV elbow as well as a nasty mass air flow sensor. At least it has a new fuel pump, spider injector, plugs, wires, rotor, and distributor cap now 🤦🏻♂️.
The plugs are probably toast from burning either too rich or too lean.
My guess is fouled from all the misfires
@@davidmachtolff8451 the misfires were caused by either a rich or lean burn. The ECU didn’t know how much fuel to give it, so it was one or the other.
@@KAS_Motorsports that and very little spark. Carbon tip was gone on the dist cap.
Happy New Year
Sneaky early video view. Hi Ray!
Saw the lower.......Cool beans.
I would have check the TPS for linearity, I had issues with one on a old 92 3.8L(with 82k miles, yup it was not daily driven) for decades with loosing power when getting on it over 3k rpm it was like dying, spark plug and wire has been replaced like 15 years ago with no difference. I mostly resealed the intake, replace a bunch of hoses, some showed sign of crack some not but they were original. I have also replaced the fuel regulator but no change. I never had check engine light(the bulb work, and Iknow pre OBDII so yeah...) when it was loosing power I kind of pumped the pedal and it make it better but not always and only had issues when engine was at temperature never when cold. I replace the O2 a 30yo sensor... clean the MAF. So I took the mulitmeter in restor mode and sure enough past 60-70% it was not going linear. I replaced the sensor and voila! problem solved. It had also a bad smell at idle when we parked it in the garage and now it gone, no more smell!
Tighten a battery up, it can cause weird running issues even.
Spider EFI or Ignition, and those caps get corrosion
just watched the video on the Sonata where you unboxed your scan tool. Crazy to see how much slower it operates now
I call the rotary button a "Lightning Whirler"
