Anyone replace a Throttle Position Sensor?

If so, what were the symptoms?

Thanks

Yes, felt like i had a hole in my map, just miss fired bucked and jerked. At a certain position of the throttle it would just wig out and then act fine before or after that point. I checked mine with my volt meter (1) Signal to ground 1v-5v and Sensor power to signal (OHMS). It was pretty easy to tell for me as my volt meter would act a fool with erratic readings when it hit the bad spot in the sensor. It should just increase and decrease Voltage and resistance steadily.

yea, i got a weird idle too, sometimes it would idle way high like 2k, other times it would just stall on me. on occasion, she'd purr like a kitten.

Thanks, guys,

I detect a sort of stuttering at a certain throttle position. Putting the auto tranny in "Sport" mode helps bypass that position, but I also notice that if I brake hard at a stop, the engine conks out. This rarely happens but I suspect the TPS is at fault.

Where did you buy yours - the dealership? Is it a simple swap and is it expensive?

Okay, I found that at Rock Auto, a Standard = $41.79, a Beck/Arnly = $63.79, and an Airtex/Wells = $76.79

It looks fairly simple to install but I'll check with my service manual to see how to test and install if necessary.

its four phillips head screws and the removal of the connector to replace it. 2 of the screws are holding in the tps itself, the other 2 are holding in the wires. very easy job.

Great, thanks, Andy.

no problem. i have a brand new throttle body sitting next to me that i'd offer you if you had an n/a.

I ordered the $42 Standard from Rock Auto and specified my exact model, but thanks, anyway.
