My car has been acting really wierd lately. Sometimes it just decides to rev on its own or the rpms dip bellow 500. Once it even stalled itself. I am pretty sure that this is the tps. Can I bring the car to the dealership to have it replaced? My real concern is that my car has a tune and I dont want a new tps to mess with it. I don't have my SCT with me, i'm in college and didn't bring it. WIll any of the recalibration of a new tps mess with the tune and require me to use my SCT(that I don't have with me). If the dealer wont replace it because of my modifications,is it easy to do, if I just get the part?
Thanks

 

i recommend you return the car
to the stock air intake and tune
before taking it to a dealership.
this is to prevent any problems, if they
decide to reflash your pcm

 

I agree with hammeron but you also dont list any mods so that is no help either, i assume you dont have an aftermarket TB but if you do then that is the problem probably.
