My cherokee just died on me while i was idling at a stop sign and now its been idling really weird. Could it be the IAC valve or something else?

Could be

You need to do some investigating/diagnosing. IAC is a great possibility. Pull it and clean it.

When was the last time you did a tune up?

When was the last time you changed your fuel filter? Ran injector cleaner?

When was the last time you did your air filter?

Hook up a code reader and see if it's throwing any codes or has any stored codes. Do you have a check engine light on?

We have no frickin' idea what year, engine or whatever Joey's Jeep is.......

This is true. Hence my vague first response. Second response was me feeling a little badly... Trying to be helpful.

But yeah, a little more info would would help us help you

You need to toughen up!!! LOL,

Its a 98 xj with an inline 6 4.0 liter. I just did the air filter but i dont know about the other stuff. I just bought it. The guy said i should replace the wires and spark plugs tho. But it wouldnt die because of that would it?

Certainly could. Best to know what you've got Install some NGK plugs, Napa Premium wires, cap and rotor.

Joeymb95

Thanks. I'll do that and let you know.

I agree that a complete tuneup is really the best starting point for any driveability problem.

The importance of secondary ignition parts cannot be overstated.

If you're chasing a problem and you have old tuneup parts, you might just be chasing your tail. Simple stuff first. Always.

i agree with previous posts. clean everything up, catch up on maintenance, and then go from there.

my guess would be either the iacv or something with the fuel system.

make sure a fuel filter and some injector cleaner is part of your tune up.

Joeymb95

Ok so since this was posted ive cleaned the iacv and throttle body, put in NGK plugs and a new NAPA premium wires. Ive also put a fuel treatment and injector cleaner into my gas tank with a full tank of gas. It still takes an extra second to start after sitting for a while (unless I prime it first) but it hasnt died on me yet... (Keyword YET) is there anything else I could do to try and prevent this from happening?

Cap and rotor?

Check to see all your intake manifold bolts are tight.

Joeymb95

Ive done the cap. Im kind of intimidated to do the rotor because ive never done it before and cant seem to find good instruction

Lift the old one off and reinstall the new one so it's seated down like the old one was.
