    https://www.gmt400.com/threads/maf-parts-cannon-story-paying-it-forward.66441/ Here is the Long Version of this issue. End the end I replaced a ton of stuff. All in all it was and still is the MAF (3 total) , or how the VCM is reading it. But with all codes cleared, I can drive the truck much...

    MAF - Parts Cannon Story - Paying it Forward

    I love everyone's enthusiasm, thanks Fam cuz im whipped. @454cid The app as awesome as it is, does not graph. I am in line for the Scan tool in this forum. I want to graph the fuel trims against each other with and without MAF, Annoying because i work at a chemical production plant and the DCS...

    MAF - Parts Cannon Story - Paying it Forward

    Well y’all, I’m defeated. MAF connected runs with slight mis-fires counts on random cylinders. With out DashCommand I couldnt tell. Once she gets up to about 60mph backfires (kinda warm weather) previously cold weather no issues. No codes. When I unplug the MAF and she toggles to to Speed...

    MAF - Parts Cannon Story - Paying it Forward

    @termite Havent yet, i replaced the one on the CrankShaft position just due to wear and tear. Easy and costless ill do the same here im sure. Thanks for mentioning it will have a MAF Code, I'm so blindly eager to get to the scanner, I'm sure i would have forgotten to clear it first, drive it let...

    MAF - Parts Cannon Story - Paying it Forward

    Well, I thought she was fixed but no. On the way to work this morning as i started holding 60ish MPH, she starts backfiring again (Original issue before the first part ERG was replaced). I pulled over and unplugged the MAF and got back on the Highway. No Popping, no backfires. @someotherguy ...

    Intermittent High Idle

    Your gauge could be reading different from the VCM is getting. Your dash temp gauge and the Ctemp sensor are 2 different items. The dash gauge element is on the driver side under exhaust manifold between C1 and C3 spark plugs. The CT Sensor for VCM is on the front of engine left of EGR Valve.

    MAF - Parts Cannon Story - Paying it Forward

    Ok, well ****. Look at this So could be a few things that happened. Either the shop installed a faulty MAF or, They didn’t replace like they stated. Maybe the tech forgot or I don’t know. The one that was in looked dated. I am going to discuss this with the owner. She drives great again. And...

    MAF - Parts Cannon Story - Paying it Forward

    I agree completely. What I meant is it wasn’t a $40 Amazon special, no it wasn’t the 180$ ACD, they didn’t stock it, it was a Duralast $111, which I guess I consider “good” not best or preferred. The scan tool showed it reading 11g/s not running. (Should read 2 g/s). So I played with wiring...

MAF - Bought the first one AutoZone good quality (returned it), as for the shop, don’t know what they put...
