What is the "other sensor" attached to the air cleanr at 2:13? A vacuum modulator solenoid for the EGR? Also, did uou ever make a more detailed video on how to test a MAP sensor? Are their charts that correlate sensor voltage to engine vacuum?
Unfortunately not, and since this was Kyle's truck (he never keeps a truck for more than 18 months), he sold it. The job is very ready though.. just a couple small bolts on the side of the throttle body!
Could these cause crank no start? I’m on a budget and I need my car working. I changed the distrubor cap, rotor, icm, battery. Alternator is good. So as it cranks it looks like the throttle body isn’t opening and the injectors gas is just hitting the throttle body doors ? Could this be one of these ?!!?
They could, but not as likely as some other things. Did you already do a compression test and confirm spark? If both of those check out, and you're certain the fuel pressure is good, then you might go with a Crankshaft position sensor first. You can probably find that sensor for $10
They always get pretty hot You should use an infrared thermometer and take a measurement to see how hot it's actually getting instead of just going by color if it is truly overheating it could be plugged
Do you have a misfire? That's be a lot of unburned fuel to get it to heat up that much. Could also be a bad o2 sensor causing a fuel dump. Check your MPG by hand.
Not yet we haven't! We're behind in the shop, unfortunately you might have to find the video from another channel at the moment. If you have a multimeter you'll be in pretty good shape to check the voltage by back probing the connector. You'll have three wires. One end will be ground, the other is a 5v constant reference wire. The middle is a signal wire (based on vacuum). Signal is usually 1 or less volts with engine off. 1-2 volts at idle. 5 volts at wide open throttle (engine running). You can test the sensor with the engine off by doing the same thing, but applying vacuum with a hand pump. More vacuum = idle (20ish in HG). Less = WOT (5 or less). Hope that helps!
dude you're a wizard. thank you for sharing!!
Appreciate the comment! There's more magic to come, we ain't done yet!!
You splain very good about to the lines. Thank you so much.. 🙌
Kyle has been known for his 'splainin

Air temperature sensor.
We have not made that video yet, but we should get on that! Stay tuned.
Great. Do you have a video on the throttle position sensor? 1986 S10.

My 93 s10 2.8lt catalic converter turn red when it heats what can be wrong?

@NiceGuysGASS I'll check ,muffler smell gas raw

I'm trying to figure why my engine will slowly climb in rpms while idling
Any thoughts?
Yes. Vacuum leak, bad IAC, or dirty throttle plate... if those all check out it could be a coolant temperature sensor but that'd be less common
I have a 1993 and my hoses are not the location provided
Well, where are they?
@@NiceGuysGASS someone grinded it down and sealed it I had to buy a whole new TBI
That does make it complicated
You never made another video on how to test the map sensor.
