2000 Chevrolet Blazer Question: Engine runs sluggish intermittently. Replaced MAF and ran fine for 1 day only.



, Queen Creek, AZ, July 01, 2013, 00:44

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.

    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.
