WTH is wrong with my jeep?

OK guys, the past coupla months, with the past few weeks getting more constant, my car will hesitate? (i think thats a good word for it) i really cant explain it, it will go then slow then go, etc until i mash the pedal...anyone have any idea what the problem is? thanks!

Re: WTH is wrong with my jeep?

What do the RPM's do? SO when your pressing the pedal it doesn't do much? Maybe the Throttle Cable is getting stuck?

Re: WTH is wrong with my jeep?

Chrysler mechanics refer to it as "surging". There is a TSB for it. Mine did it. But then they flashed the PCM. Hasn't done it since. It's not a big problem.

I had 97 dodge 4x4 truck that did the same thing. Going back & forth (surging) just when i would go up hills. It was like riding a bucking horse & it was aroud 1500 or 2500 was like it was tryin to lose power. took it to a couple of mechanics they said it was my o2 sensor. I didn't belive them but i went ahead & changed it. & i'll be damn it never did it again. Not saying that could be the problem but it might be worth checking.

Re: WTH is wrong with my jeep?

I went for a trans fluid change and I think......hell I don't know. Lol. I just paid. I think I paid just over $200 with the fluid change. They updated multiple stuff but only charged me for one flash though I think. That's the vibe I got from the mechanic.

The dealer I go to are pretty cheap. They only charge ~$70 an hour.

But I had the same problem you did.

The surge is in between 30-45 mph at about 1,400 rpm's

Re: WTH is wrong with my jeep?

Is there any warning lights, specifically the one that looks like a lightning bolt? Mine did something similar a while back. Turned out to be the throttle.
