TPS Sensor Bad?

[krummel21]

When in any gear if I take the car to 3000 rpms or more, and if I gas the car up a hill at any rpm; and put the car in nuetral the rpms will drop and kill the car. I have a recirculation tube so this shouldn't be the cause. Could this be my TPS sensor going bad or would it have to do with the fact that my car isn't tuned.

I was reading could this problem actually be cause by a dirty throttle body or would it more likely be my AIC motor going out or needing cleaned? If so how would I go about cleaning either of these?

Did you check to see if an intercooler piping boot came off? Also, look at the tps sensor is the screw on it centered. Did you add a mod then it did this, or did it just out of the blue happen.

All the mods were done at once so I can't really narrow it down there. But the prolem did start after I modded the car which kinda makes me wonder about the tune.

I'm having a similar problem, whenever i am in positive boost above 10psi and let off the the gas and hit and hold the clutch in my car dies, or if it doesnt die the revs go down to about a 100 and almost dies but comes back on. I did get a code for TPS malfunction a few months ago but i erased it and it hasnt come back on anymore.
I'm going to try switching my TPS to see if thats the problem.

If that helps please tell me, I just got done cleaning my throttle body hoping this woul clear up some of the problem. I haven't driven it yet to find out though.

Did switching the TPS ever help the problem you were having? i am having the same problem.

Based on the description of your problem, the cause that I would first suspect would be a faulty ISC motor. Something you could try would be to have your car idling and then turn on your air conditioning (if you have air conditioning) - your car should continue to idle and your RPMs should increase a bit. If your car stalls or the RPMs drop significantly, this would again point to a faulty ISC. You may also want to test your ISC by disconnecting the wire harness from the ISC and performing the resistance measurements as mentioned in the service manual. Hope this helps!
