hi every one, i got a question
why does my car run better with my tps unplugged? my 3sge has a wimpy cold start and suffers from an iratic idle, fine until it comes off cold start at the point my temp needle reches just under half way. on cold start it will start first time but just sit at idle then if left for around 20 30 seconds it jump up to 1500rpm and happly sit there untill its warm then the idle when warm will dive to just above 600 rpm and car will shake but after 10minutes worth or driving itll settle. anyway i forgot to plug my tps back in after working on car saturday and i fired up the car and it started perfectly and drove fantastic and had super throttle respone, only down side was it hunted on idle only about 300 to 400 rpm once warm so whats the deal? why does car run better once tps unpluged???? |

Yes, that's right. It comes on to show that the ECU is getting power then goes off when the car is started, unless there is an issue. Do you have a multimeter to test your TPS?
