At higher mileages (125,000+) the Mass Air Flow Sensor may cause the vehicle to idle rough, run rich and even stall. Our technicians recommended to replace the Mass Air Flow Sensor with a factory unit because the aftermarket units have very mixed results.

Well mine is pretty much doing this I just got the heads and gaskets rebuilt. A few macs all told me it sounds like a cinser gone out. But yes u crank it it blows out a lil black smoke like its getting to much gas Like it's missing real bad but when u hit the gas it sounds fine u left off it dies. Can somebody please give me some pointers. I love my truck But damn I've put enph money in it
Runs like new until the engine warms up then starts missing and backfiring. I can actually turn the ignition off then back on and it trys to clear it up but comes right back. I can smell almost stale gas when it starts missing and backfiring. Haven't had a chance to put a code reader on it because I can't find anyone who has one for the year of my truck. Any help would be greatly appreciated. Thanks, Redfish48
