99RegalGS Posted September 18, 2003 Report Share 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 Link to comment Share on other sites More sharing options...
Robby1870 Posted September 18, 2003 Report Share 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 Link to comment Share on other sites More sharing options...
99RegalGS Posted September 18, 2003 Author Report Share Posted September 18, 2003 I forgot to say this but I checked the IAC sensor and it was fine. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted September 18, 2003 Report Share 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?

99RegalGS Posted September 18, 2003 Author Report Share Posted September 18, 2003 Yes it was clean. It doesn't hesitate at stops. The idle fluctuates a little but not constantly. Quote Link to comment Share on other sites More sharing options...
