Product Q&A

I have a 2002 silverado that is in engine reduced power. I've changed throttle, the tac, tps, pps and im still getting the code for multiple misfires would this be the solution or could it possibly be that the throttle i semt to you guys to rebuild could still be faulty?Juam R.Jan 05, 2021

Best Answer:Hello! I recommend having your vehicle scanned for faults. If you let me know the fault codes you have, I am happy to help diagnose further!

I HAVE A 2005 2500HD REPLACED MASS DID NOT GET ONE WITH TEMP WHEN COLD WEATHER CHECK ENGINE LIGT ON WHEN WEATHER WARMES UP LIGHT GOES OUT WILL THIS ONE CORRECT PROBLEM?doug s.Dec 29, 2020

Best Answer:Hi Doug, I don't think this part will solve the problem. A Mass Air Flow sensor (MAF) is one of the key components of an electronic fuel injection system in your car. Cold temperatures may be causing the gas cap seals to be stiff and not seat properly on the end of the filler tube and cause the engine check light to come on and this usually disappears in warm weather. Try changing the gas cap first.
