@@WrenchSense other than plugs, wires, and distributor issues, what else could cause mis-firing? I've got a 98 gmc with this motor, I've had the 3 things above replaced a few years ago and I'm having issues. I will say that the truck is used sparingly.... basically a plow truck. I've heard moisture under the cap can be an issue. I did have an exhaust leak that I fixed, the mis-firing isn't as bad but still there.
@@WrenchSense Why didn't you reference the proper gap listed on the sticker of the fan shroud? You could have referenced the gap you set the plugs at with your feeler gauge tool. Example like I have a sticker on my 1995 Chevy 5.7 liter TBI, stating set the gap at .035 and recommend factory AC Delco CR43TS Plugs.
A good rule of thumb on those peanut plugs without washers is turn it one flat, or 1/6th of a turn, after it seats in cyl head. Learned at A.S.E. school. This, of course, if you haven't got a torque wrench!
Actually, I have the 1999 k1500 4X4 Z71 5.7L Vortex with the distributor it was the last year they made those. I have had this truck since 2008 . But, it is considered the Cross over model.
Dang, was hoping to see what it looked like to remove the air ducting so I'd know what order and what exactly needs removing. Otherwise, great video- I feel a lot more confident in how to approach and complete this tuneup. Thanks.
I installed higher omm coils from jeggs onto my obs chevy and i changed that and spark plugs and for some reason my engine started to shake a bit after what should i check maybe something i missed not sure need help
So this truck has a notorious problem with wear on the distributor drive gear causing a random misfire. I have seen it dozens of times. Take the distributor cap off and see if you can rock the rotor shaft back and forth. If you are getting too much play in there, the whole distributor needs to be replaced. Sorry for the late reply. Hope this helps and thanks for watching!
Would this be the same for a 98 gmc sierra k1500 5.0. We changed plugs and wires. Ran good then got cold(mn 2020) and started a one morn and check engine came on and started flashing when driving to work. So confused.
You know your video would be nice if you said what you were gaping your spark plugs too? .50 .60 ? Also what are the numbers on the spark plugs? You need to fallow up more.
The 350 was not discontinued till 2002. The 99 tahoes still had the 5.7 350 engines. I have one. A bit misleading for someone wanting to get parts. But a good know how video
Great video, but I have a 99 Yukon which is powered by the 5.7 Vortec NA engine. Not sure if what you're saying is that's the last year that engine was made, or offered -- but I got one under the hood, so... Other than that random comment, very informative vid, thanks.
98 was the last year for GMC and Chevrolet 1/2 ton pick ups to have the 350. There are a rare handful of 99 classic trucks out there that still have the same body design and the 350. 99 was also the last year for Tahoe, Suburban, and Yukon models to have the 350 engine.
My 2000 Yukon Denali also has the 5.7 Vortec. 2000 was the change over year for this vehicle. When I order parts I always order parts for a 1999, as the Vortec AND the LS motor were available in this particular 2000 model.
It's a good video and all but I've watched 1520 of them right now and I have not yet one of them show me where to put the spark plugs at for my timing order on my cap for a 97 Chevy vortec I've asked many times no one will show me
I appreciate the video but maybe you should just tell everybody what order they should be in from front to back on the distributor cap so we know which one goes to which port
Name the items product brand or item# wanting to know witch items are best used and reason like if cooper is better then aluminum or it don't not matter.. but over all video is great..
I was hoping you would say what that engine was supposed to be gapped that but you're not once so far have mentioned the actual Gap number I have a carburetor version of that motor Google says 45 lol 😂

Thank God for people like you sir that take time out of their day to teach this to us and save us money! Well played sir!
Glad to help and thanks for the comment!

I agree
After watching this video it gives me the confidence to give this job a try. Thanks for taking the time to help me, and everyone else.
1999 is the last year of the 5.7L Vortec V8. I have one. The next gen vehicles started in 2000.
What month in 99 was yours made? I think they changed it mid year
@@palmtree_04I have a 99 and it says vortec right on it
@@El_Devyl but what month in 99? I thought they switched over mid year of 99
Ya 99 was weird, new body styles along with motor, I think 1 ton and 3/4 ton kept the old body style for a bit 🤷🏽♂️ 99 kept everyone thinking haha
They still made the 5.7 for the ck2500 and 3500 up until 2002. Only the 1500 ended with the introduction of silverados
This is excellent! Very well narrated and very helpful, lot of great tips. Thank you for sharing!
You bet! Thanks for the comment!
Very helpful, my son just bought a ‘98. Looking forward to seeing more, thanks.
Right on

This was such a thorough video! Thank you!
Thank you for this video! Very well done and I going to tackle this project today.
You bet! Glad people are still getting use out of my old videos. Thanks for the comment!
Thank You...Changing mine after work today..
Awesome video. You're a natural teacher! Thanks!
Always a good idea to keep the throttle body clean
Thanks for the info Dane cook you rock!
It's a secret..... I keeeeel You....
Thanks for explaining everything so well. I think I can go do this now
Actually, I have the 1999 k1500 4X4 Z71 5.7L Vortex with the distributor it was the last year they made those. I have had this truck since 2008 . But, it is considered the Cross over model.
Same here!
If anyone was here for the gap it's 0.60 on the 5.7 Vortec using AC Delco platinum.
Thank you, but I don’t trust you.
Nice work on the video! Thanks so much for doing this!
No problem. Glad I could help.
Thank you...a very good informative lesson.
You bet. Glad to help.
Step by step great instructions , 🤙🏼
Very nice video bro! Thank you!
No problem 👍
great job. Well done and very helpful.
Just made my life alot easier 🤦🏽💯😂😁 thank you

So informative
I got a 97 it's a great truck ain't they
Fire it up I wanted to hear that baby roar
Thanks man, big help!
I installed higher omm coils from jeggs onto my obs chevy and i changed that and spark plugs and for some reason my engine started to shake a bit after what should i check maybe something i missed not sure need help
This video really help full . appreciate it
Thanks man, got the same truck very helpful.
Very cool. Glad I could help!
Great video. Thank you very much.
Great! Glad I could help!
Would old wires, plugs and cap/rotor cause a random misfire?
Yes
Yes. idle bad ride horrendous

Bad intake manifold gasket also causes random misfire.

Make sure your gapping and plugs are correct
What if your truck doesn't have that sticker on it how would you know what the Gap would be
Do you have to have dielectric grease for the wires? I just started the job and already got one out but don’t have any
What about timing? What if the distributor was rotated by accident?
Thanks bro your awesome 👏
1999 Chevrolet suburban 5.7 liter C1500 gas Vortec 350 small block
Very helpful
You know your video would be nice if you said what you were gaping your spark plugs too? .50 .60 ? Also what are the numbers on the spark plugs? You need to fallow up more.
Which spark plugs do you recommend? AC Delco 41-993? There's platinum, iridium, etc. Gets confusing. Thanks.
iradium is the best for that engine
thank you for the video. i have the 98 sierra 5.7 vortex
Very cool! Thanks for watching!
Is it common for spark plugs to not exceed a gap that is less than what the engine requires? I.E., Plug not to exceed .55 with a .60 gap needed.
So how come you didn't say firing order on yours like 2+4+6+8 etc
The 350 was not discontinued till 2002. The 99 tahoes still had the 5.7 350 engines. I have one. A bit misleading for someone wanting to get parts. But a good know how video

I appreciate the video but maybe you should just tell everybody what order they should be in from front to back on the distributor cap so we know which one goes to which port
Aren't they supposed to be Iridium Spark Plug ?
should be yes
@@johnnyutahhh4563 I got iridium on mine but not sure if the one you got are better
What's the hardest spark plug to get to what number is that
Do I have to take out the heat shield and how often do you have to replace the cap and rotor
How often do you do this
How often should I do this
Every 100 thousand miles or so
Name the items product brand or item#
wanting to know witch items are best used and reason like if cooper is better then aluminum or it don't not matter.. but over all video is great..
thank you how to no what wire go where new wires have no nomber
Thanks
You bet! Thanks for the comment!
False 99s had the 5.7l 350 halfway thru
needs to show the beginner how to undo the clips that hold the wires so they dont get broken
Dude! Really? Will say not a good idea to work on it then.
good video!!
why does this video look like it was recorded in 2008
It was a crappy camera. Hehe
I have since upgraded.
1999 is last
Noone seems to know the firing order
And if you make a million dollars off of showing people let me know thank you good

I was hoping you would say what that engine was supposed to be gapped that but you're not once so far have mentioned the actual Gap number I have a carburetor version of that motor Google says 45 lol 😂
I avoided saying as much because I am aware that different engine years and builds have different requirements.
This should be about the same for the 305 im thinking
