Howdy guys- could really use some help diagnosing a warm engine only (only when at normal operating temp 190+), RPM dependent (around 1265 and 2200 rpm), ONLY when in DRIVE, engine rattling that seems to be coming from the front (bumper side) of the engine...no decrease in engine performance, spark plugs pulled and look normal (no pre-ignition signs), using a little oil (about normal for this engine), coolant normal.
I've included a video of the sound at 1265 rpm...as soon as you go above or below, the rattling noise abates... no obvious heat shield rattling detected...I have gotten P420 codes before, but doesn't seem localized to the cats...seems to be coming directly from engine front...Bobby at CruiserCo was kind enough to take a look and said he thought it might be dieseling...seems like classic dieseling involves wanting to run after shutting off though? Any thoughts guys?
