Whether it's induced by your programmer or is just one of those maddening coincidences is anyone's guess; since both PCM and HVAC Control Module involve 'memory' it may not be coincidence. If your recirculation controls are working properly I'd clear the DTC and not worry about it unless it recurs. If your controls are not working properly you may need recalibration or some other action which means a trip to the dealer, (after restoring factory program). -David

Replying to: dale3n8 (Feb 20, 2006 7:21 am) What you are describing sounds to me like a problem with the ABS system. Either way it is a warranty issue and should be addressed by the dealer.

Hi, new member here! I have a 93 GMC sierra 1500. I just put a new crate engine in the beast and thought with new sensors that the SES light would go out! (That wasn't the only problem with the old engine-long story). I still get a code 43! That's the anti-knock sensor. It's a brand new one! Will it hurt the truck to run it with that going on? Will there be any long-term damage? The mechanic I who put the motor in seems to be avoiding me about this problem. any help would be appreciated.

My 2006 four door 1500 GMC is at the dealership due to the right side door windows not working. I'm told the problems maybe in the multiplex wiring. When did GM begin using Multiplex wiring? Has anyone else experienced this type of problem? |

| I have a 2000 GMC Sierra with the 5.3 engine--50,000 miles. Occasionally the truck will not accelerate. The engine rpm's will go to about 1800 and the truck will not accelerate past this point for a short period of time. There appears to be a backfiring type noise. I have replaced the fuel filter and the complete module in the fuel tank. The engine runs fine if you are in park--no hesitations through the entire rpm range. This problem only occurs with the transmission engaged. No codes are showing up in the computer. Any help will be appreciated. | |

| I have a 1994 GMC sierra 1500 that cuts out when idling but once I give it gas it is fine. I have replaced the fuel filter and it hasn't helped. When it starts to cut out the brake light on the dash lights up, is this significant? Someone told me that it could possibly be something in my gas tank causing the problem, is that something I should get checked? I also changed the plugs and wires in case it was a faulty plug causing the problem. If anyone has an idea of what I should do next please let me know. Thanks! | |
