Great explainer. Thank you! Do you have anything about high idle? I changed the IAC, checked vacuum lines and still nothing.

@DEInTheGarage 6 жыл бұрын

Did you try cleaning the throttle body? Sometimes the build up on the throttle body or inside the IAC housing will cause a high idle situation. When you checked the vacuum lines, how did you do it? Leaks can be hard to detect and even a small leak (a stretched elbow fitting or hairline crack) can cause a high idle. 4.0's are notorious for vacuum issues. Outside of the easy stuff, check that the wiring on your IAC is all intact. I have heard of cracks in intake manifolds causing idle issues as well. Long story short, high idle can be any number of things, best way to solve it is to spend some time under the hood with a fine toothed comb. Good luck! Hope this helps!

Your explanations of what the MAP, IAC and TPS do was the best I've seen. I plan on cleaning my throttle body this week or next. Thanks for posting this.

Man oh man, you got me through not one but two things I've had holding me up for a whole day in getting my throttle body and IAC sensor off. Dadgum cable #2 was seated in a weird way, so glad I found your video so I didn't break it. Then my IAC was stuck on there bad, I unbolted from the unit but it was still stuck. When you said it should pop off, I got a flathead and sure enough, out it came. I owe you man! 🍺 I have a gorgeous '06 JGCL Ltd. Getting worked done that it's needed for awhile and being able to do it right on my own is just the best feeling ever.

Tape, clean rags, whatever works best for the situation. Keep calm and Jeep on!

Observation. Just remove the air filter cover for more room. 4 clamps :( also, when removing the throttle body cables, make sure you show exactly how to remove them. I thought i could just "pop" off the cruise control cable. Well, I broke the the plastic piece. Try replacing that :( I had to get one made with a 3d printer. Instead, you need to 'slide' it off the cable. I ended up super gluing it back together but it was definitely a problem that could have be avoided. Anyway, just trying to give some advice to someone who may have this problem. Cheers

I have a 1994 Jeep Grand Cherokee with a 5.2 L V8 and am replacing my IAC soon (engine randomly stalls). I appreciate your explanation of all of the sensors connected to the throttle housing and what they do and what symptom problems each one may exhibit when they start to fail. I will be pulling my throttle housing off of my engine to do a thorough cleaning as you had suggested to get all of the carbon deposits off of the throttle housing for a better running engine. P.S. I also suggest having one of those long retractors tools handy when working on this area as I initially dropped a cleaning pad down into the throttle housing body and had to walk to the auto supply store to get one to retrieve that cleaning pad. Live and learn.

@DEInTheGarage 5 жыл бұрын

I would ensure that your injector and spark plug are sealed correctly. With the spark plug this can be as easy as removing it and inspecting the plug itself and the housing around it for cracks. The injector has o-rings on both sides. they can crack or stretch allowing moisture to effect fuel delivery. If neither of those are the issue, perhaps look at the wiring to the injector. Worst case would be a head gasket or cylinder head crack at the 6th cylinder, but that really wouldn't only happen when it rains

Thanks for not pretending to know-it-all. You already know A LOT! Does not having the wire through the accordian hose mean that I don't have a Mass Air Flow Sensor on my 1999 Grand Cherokee 4.0L? I have been getting intermitant engine cut out while driving down the road. Some folks attribute that to the MAFS. I bought it with 60K miles on it and put another 145K on it. The rear driver window started opening whenever it felt like it. I installed a salvaged Body Control Module and it still does it. My next guess is the window control inside that door. Any other suggestions? I am glad you like making these videos. Please continue!
