99RegalGS Posted September 18, 2003 Report Posted September 18, 2003 My car has been misfireing and backfireing for about 2 months now and last weekend I finally Checked the Computer codes. I got one for the IAC, MAF, TPS and two for the Cruise. The wierd thing was my IAC wires are grounded (no power) and my TPS power is 2 volts when it's suppost to get 5v. I didn't check the MAF or Cruise. What's wrong? Is it the computer or the wires? Thanks. Quote
Robby1870 Posted September 18, 2003 Report Posted September 18, 2003 Get a new TPS and clean your IAC and/or get a new one. Those codes can throw other codes.... Robby Quote
99RegalGS Posted September 18, 2003 Author Report Posted September 18, 2003 I forgot to say this but I checked the IAC sensor and it was fine. Quote
Robby1870 Posted September 18, 2003 Report Posted September 18, 2003 I forgot to say this but I checked the IAC sensor and it was fine. The pintle was clean? I would change the TPS, they are non adjustable. Does the idle fluctuate a lot at stop signs? Does it hesitate when taking off from a stop? Robby Quote
99RegalGS Posted September 18, 2003 Author Report Posted September 18, 2003 Yes it was clean. It doesn't hesitate at stops. The idle fluctuates a little but not constantly. Quote
