    MDS Delete SOLVED

    Just wanted to share this, pulled the trigger and had my ECU tuned to delete the MDS from functioning. Super simple, mailed my PCM out and he mailed it back with no more MDS!!! The guy said if sending in my current PCM wasn't an option, that sourcing a used one could work too. Can't believe I...

    Loud knock

    I have a 5.7 hemi with 110000 miles and I recently got a bad tick/knock. The last owner had the truck taken in for a snapped valve spring, and I think another one snapped. I’m not sure, could it be lifters? Sounds like it’s coming from the heads with the stethoscope. Also is it safe to drive on...

    Strange Engine Noise

    I know there are plenty of threads out there already on engine noises for the 5.7 Hemi. Just needing a place to start, took it to dealership a week ago when this started. They told me it was Camshaft and lifters but they did not tear into it. I didn’t believe them as there is no engine codes or...

Fuel level is never below 1/4 tank, so...
