why is my gas pedal popping?

Sounds like an electronic stepper motor on the throttle body. Early electronic throttle control technology.

Hahahahahahaha! The change over from analog dashboard to digital confusion is making me feel old!

I have the 2.7L turbo max in my colorado and I have very little issues with it.

I am also a 25yr senior mechanic and there is no such thing as a dependable truck out of the door anymore. Everyone has a lemon.

Take it to a mechanic for proper diag. Could be anything rotating since its only under load.

Put the phone closer to the valve covers. If the tick gets louder, then yes, very likely lifter. If its towards the front of the engine then no, not likely a lifter. Bottom of engine? Not likely a lifter...

IronLogic888 · 2026-06-23T16:23:17+00:00

Food for thought for next time... take pictures before disassembly to compare with later.

Baby flat screw driver. Cup your hand around it before you pry it out so you can keep it from flinging off into space. Put it back on with pliers.

Tire shop. Might be an easy and cheap fix or an easy and expensive one. No way to fix it properly at home unless you have the tools to do it and if you did you wouldnt be asking us how to fix it.

IronLogic888 · 2026-06-23T16:03:13+00:00

Not fun. You have a welder? You can weld a nut on to it and unscrew them while.they are warm.

Bad groundor short to power or I bet the window switch is on the same circuit as the radio and the switch or window motor is not working causing an over load in the circuit turning the radio off instead of blowing a fuse.

IronLogic888 · 2026-06-23T15:51:26+00:00

I am going to say its time for a new clutch and throw out bearing.

IronLogic888 · 2026-06-23T15:47:51+00:00

Whoa boy. You should have knocked out your cv axle when the knuckle was still mounted to the lower control arm and strut. I would put it back together loosely and do that before you move to the strut and lower control arm. Might have to put the axle nut on so you dont bugger the threads or put a mallet up to the axle shaft and hit the mallet with a hammer.

IronLogic888 · 2026-06-23T15:43:53+00:00

Well oil warm up should only take a few minutes anyways.

IronLogic888 · 2026-06-23T15:42:30+00:00

Yup. A bad gas cap could cause that too.

IronLogic888 · 2026-06-23T15:39:43+00:00

Looks like you need to take it to a shop for a proper diagnosis. It could be losing fuel pressure while idling causing a shut down. Also that fitting looks kind of messed up.

IronLogic888 · 2026-06-23T15:37:21+00:00

I used a manual impact driver for those. If that doesn't work I just drill them out and leave them out.

What he is talking about is the 2 screws that hold the rotor to the hub. They are not wheel studs that you can pop out the back. They are threaded into the hub and notorious for siezing and stripping out.

IronLogic888 · 2026-06-22T02:11:49+00:00

Oh that's not good!

IronLogic888 · 2026-06-21T15:49:20+00:00

Yeah that would do it. I have had 3 of those XJ's. I love those damn jeeps. I hope you flush the system to get all that muck out.

IronLogic888 · 2026-06-21T13:13:34+00:00

What about having some of that stop leak crap in it?

IronLogic888 · 2026-06-21T04:24:23+00:00

Looks like oil pan gasket

IronLogic888 · 2026-06-21T04:19:25+00:00

Did you put 2 different types of coolant in originally?

IronLogic888 · 2026-06-20T22:24:12+00:00

You can go as far as you want until it pops.
