Jeep started hestiating or bucking at speeds from 25+ if held constant at that speed. Thinking the TPS was bad I replaced it and had the dealer adjust it. THye told be at that time my O2 sensor was bad as it was not closing the loop but remaining open. Ok, I had replaced the O2 sensor about three months ago, but I warrentied it anyways and replaced it. Still have the bucking. Took it to the locla shop and they said it was my exhaust manifold leak. I have had a small leak for about 2 years and never any big problems. They said the leak was causing the O2 sensor not to to close therefore running rich.
This however is the exact opposite the Jeep dealer said. They said the leak was there but wasn't big enough to cause problems and didn't sound like it was sucking air in. And the dealer here is very good and I have every reason to trust them.
So I'm wondering what other things might I check that would cause this annoying problem. Should have never replaced the TPS as it didn't seem to be bad, and with 190k on it.
