CHEVY MAF SENSOR

1999 Chevrolet Silverado

Engine Performance problem
1999 Chevy Silverado V8 Four Wheel Drive Automatic 118000 miles

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.
