I just recently rectified a problem I had where the ignition was misfiring just off idle. I suspected the MAF sensor (although it did not produce a fault code). I had a buddy that also owned a Silverado and we just swapped the MAF sensor from his truck to my truck. The problem was instantly fixed. It was the MAF sensor. I bought a remanufactured sensor from Advance ($80.00) with a fifty dollar core charge.
