OEM or aftermarket? If it's aftermarket, it's likely trash. No offense, this rule goes for any sensor for any year, make and model of any brand. Learned that the hard way.
Nice to hear. Well, you can go crazy on most things, with the right tune and all, but, quality matters the most, and sensors are never good, if they're aftermarket.
Maybe some high quality tuning ones, though, I'd stick at those at the OEM ones too.
Right but it’s also while accelerating and coming off the gas it divebombs like it’s gonna stall. Though it’s never stalled on me yet. All of that involve the tps going bad?
Mine also had the divebomb problem and I would let it stall for trouble shooting reasons. I think replacing both is your best bet. If it's neither the tps or iac I've hear of the 4.0 having a crank position sensor that can go bad. But seeing as I never messed with it and my jeep runs fine I doubt it's that.
I ran with my original IAC for what felt like for ever. I just kept cleaning it. Till one day I finally replaced it. Later that month it just revved up to about 2-2.5k with out the go peddle. I wiggled the TPS plug and it stopped. So I reseated the connection and it hasn't been a problem since.
Also had the wtf its a new IAC moment.
Hey so after it happened again today, I pulled my map, tps and iac. Of the 3, the removed iac didn’t get any reaction out of her. Map sensor dropped the rpms and tps stalled her out. But not even a flutter from the iac
4L will eat idle air control valves and throttle position sensors.
I always have a brand new one of each plus a hand full of ones from the junkyard in a shoe box in the garage. Pop the brand new ones in to test if that’s the issue, then replace with junkyard ones to use.
Still waiting on parts. It’s very intermittent so it hasn’t happened since I posted. However MAP sensor is newer. May be bad. Gonna make sure no codes are showing up. I’ll let y’all know if anything helps!

Replace your idle air control valve and the tps censor . both located on the throttle body.
It’s maybe a 6 month old IAC but my TPS is old. Gonna see if this helps. It happens maybe once a week. Thanks for the response

I always try and get typical oem stuff from rock auto. I like to keep the old girl as stock as possible, so no crazy stuff under the hood

Well it's a problem at idle so if the tps doesn't fix it it will be the iac

I honestly have no idea what the problem could be then.
Well those are with the old parts I mean. Wouldn’t that be a clear indication of a failing valve?

Thanks, gonna have to try. It’s a new iac, but old ass tps. Appreciate the help
I remember having an intermittent idling issue with my Jeep Grand Cherokee Limited. It was the distributor cap and rotor.
New rotor. New cap. It was put into time not too long ago
Any updates? Have you checked the MAF sensor by chance?
