As it states the idle on my car stays around 1500-2000 rpm's. I think its becuase i switched to a GSR TB. Could this be my problem? When i got the GSR TB I had to put a new TPS sensor on it. Could this also be the problem. Ive tried evrything I know of to back it off but its still the same. Doesnt bother me that much since i rev the hell out of it anyways but just to make it sound correct so others dont think im a dumbass ricer that dont know crap about his car exept where the gas goes.
