Ok ive it mentioned as the possible cause of a lot of peoples problems with bouncing rpms and what not. But what is it and how can you fix it?

 

its a throttle position sensor...and if its gone bad your car will run like ****...

do a search...you'll find 50 threads on TPS...

 

K, I want some descriptions of running like ****, if anyone could do it. I know we are talking lumpy idle but are we talking jerking and some smoke? Please give a description since this is what I believe is the only thing wrong with my car.

 

when mine went bad it was a lot of nasty jerking, much like someone learning to drive stick. I didn't notice any smoke or anything, just jerking.

 

yeah mine wouldn't smoke...it would still idle fine...but it would jerk so bad the rear tires would chirp and you'd have to hold on not to get thrown thru the windshield...

 

When mine died, my rev limit was 1500 and my top speed was 30...it was a fun drive home. For the 2 years I had the car before it died, it would give me some hesitation every once in a while at high RPMs and full boost. That went away when I got the new TPS.
