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 , 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.
