My truck is idling rough and the check engine light stays on. I hooked it up to a code reader and it said I had a random misfire and suggested that I replace the MAF sensor. Is there a way I can test it whithout just buying a new one and seeing if it stops the problem?

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.
