Hi Scotty! I have a 1998 Jeep TJ that keeps firing a TPS code. I have replaced the TPS two times with an O’Reillys model. This last TPS that I just replaced two days ago was a Mopar part. Not cheap. I keep throwing a TPS code and the jeep runs awful. My idol is anywhere from 1300 to 1700 after temp is reached the live data stream shows that my throttle is at 74% when the TPS is bolted on when it is not bolted on, it shows 63 1/2%.
I’ve tried answering these questions in the Jeep Wrangler forms and have had everything from the clock spring needs to be replaced to just clean your throttlebody out. I have cleaned my throttlebody and it is immaculate. It does run much more smooth, but still stalling at speed and hiccuping under load.
My daughter wants to learn how to drive a stick this Friday, and I am struggling to find an answer to make this thing run correctly.
When this all happened, I drove the vehicle home from work, and it was running just fine. I got up the next morning to go to work and it was running horribly! So literally, the current state happened overnight
I hope to hear from you soon
Best regards,
Sid, the nurse
It may be as simple as one or more loose vacuum hoses. If you haven't replaced them in the time you've owned the Jeep, you may want to consider doing it. It's almost 26 years old. That would be a good first step.
Well so many things can go wrong electronically on those Jeeps. But I would never use discount auto parts store sensors like that because most of them are made in China and they are garbage. Personally. I would start out with an OEM sensor and go from there and pray doesn't have a computer failure or some weird wiring short
Wow, this is pretty cool you actually answered! Thank you very much…

I guess next thing I can start looking at I suggested are vacuum lines?
