Truck runs sluggish from time to time. I replaced the MAF and the truck ran great for a day, then back to sluggish. I removed the plug (MAF) and ran it for a few miles and truck ran fine. Cleaned MAF with MAF cleaner and also electrical contacts w/special cleaner. Truck ran fine for one night, then back to sluggish,.. again! Something is telling my truck to run rich (I can smell gas) and electrically adjust the Air/Fuel. I cant pin point the issue yet. -spark plugs, cap, rotor, TPS, MAP, MAF, IAF all new. Coolant/tranny flush, oil/air/fuel filter changed.
Engine runs sluggish intermittently. Replaced MAF and ran fine for 1 day only. on 2000 Chevrolet Blazer

do you have any codes and where did you buy the sensor?
COMMENT by tonedox1 on July 03, 2013
there are no codes that are popping up. I bought the MAF Sensor @ O'Reileys Auto. This sluggish condition seems to happen when the engine is warmed up a little. I can make it to work, no problem. but I always notice it on my last few miles from my house when my shift is over.
