Friend of mines car idles better when the TPS is disconnected. Car pulls strong otherwise. All Turbolink specs are very good with it connected (TPS = .44, BLM & INT locked on 128 (Thrasher), IAC = 10-15) but it has a miss at idle. Went through all the basics including swapping parts from one of my cars. Just for the hell of it I disconnected the TPS and the miss dissapeared.
Triple checked this and every time the TPS is disconnected the miss is 100% gone. Manually verified TPS is good with volt meter - no bad spots. Swapped it anyway with the same results. Just wondering what compensations the ECM makes if the TPS circuit fails or is disconnected. I would guess a richer air/fuel mixture?
