Question about 1996 Jeep Grand Cherokee
I have a 96 Cherokee Country. I've just purchased it last week. When I start it in the morning it will stall itself out. It will recrank instantly, but you have to give it a bit of gas. After literally 1 second of doing this, it will idle fine.
2 times this week it has randomly cut off at very low speeds. Once pulling into a parking spot, once right after pulling out.
I just replaced the fuel filter last week. I have checked vacuum line but found nothing out of the ordinary. Could not find leak with parts cleaner.
The plugs and wires are not brand new, but less than 8 months old.
It doesn't feel like it is misfiring though.
This jeep sat a few months until last week when I bought it. The former owner battled this issue by dumping in bottles and bottles of gumout in there. That's why I changed the filter.
My other suspects are the IAC Valve, or TP sensor. Hopefully someone else has seen this issue before. Thanks!
Tap the iac valve with a small hammer and this worked for me, started idling. The jeep would shut down if i did't give it gas. Idle air control valve was replaced and fixed it.
The other problem I had was misfire in multip[le cylinders. The spark plug core needs to be alot thicker. Made the ones the parts store run too hot and foul out until they cooled down again. This is why people get the multiple cylinde misfire code.
GO STOCK, NOT THE BS AFTER MARKET C.R.A.P.
After months of "HANGING PARTS" and guessing, I found out the BRAND NEW plugs I paid 2x the price of the crossed referenced Auto Lites ( way cheaper) was the misfire problem.
I took the P/N from under the hood and went to the parts store, and got the way cheaper ones which solved it. GOOD LUCK! firstname.lastname@example.org let me know what you find out

Try unpluging the aic control valve while its off see if it will run by itself in the morning, open a small vacum port if it wont idle under these conditions if it idels without stalling i would try cleaning the iac valve with carb cleaner, you may also check the fuel injector o-rings and the coolant temp sensor if its out of range it will not enrich the mixture when its cold you may check this first its located on the block it think please rate good luck -jeff
