Hi everyone!

I am a total newbie here to the forums.
My wrangler has started stalling when I come to a stop…at stop signs…red lights etc. I took her to two mechanics and both said they couldn’t find anything wrong.
I’ve looked around the forums and have seen a thread discussing using a spray to clean the iac…as a dirty one could possibly be the problem.

I am 100% not a mechanic and have never done any diy with this car…I got the throttle body/air intake cleaner. But I don’t know how to access the air intake in order to clean it.

Any help is appreciated!!
 
This is an pretty easy deal. You just pull the air cleaner tube that connects to the throttle body.

Then look for the hole in there on the side.

Have someone start the Jeep, do not touch the throttle. Spray in there and it will die out, that’s good, means it’s in the IAC. Start and let idle and repeat. Do that repeatedly. See if you notice a difference at putting about half a can in there.

Do some more if needed.

Either way if you push the throttle then it’s not going into the iac, so let it die out and restart

Thank you! I appreciate the picture. So…I took the clamp off of the air tube and tried to pull it up…but for the life of me I can’t. It seems sealed shut! I may have to try to pry at it with a screwdriver. I wonder if it’s ever been opened at all.

Good question. I don’t recall that ever being an issue for me.it’s pretty easy from what I recall

it can get a little sticky if it's never been removed before. If you have a hooked pick it can help to get it under there and work it around the connection to peel the rubber off the aluminum, just don't get too aggressive and tear it up with the sharp point.

Also be careful pulling on it too hard, I had one come loose somewhat suddenly and unexpectedly and ended up breaking the PVC elbow fitting on the valve cover which had become brittle with age and heat.

Thank you! Don’t think I have a hooked pick…but I was eyeing a thin metal spatula in my kitchen, so I might give it a go to see if that may help me pry it off.
