P0300 caught on a log.
my car misfired at around 5300 rpms at around 133mph, diagnosis said it was also coil related. I cleaned my plugs and the coils were nice and dirty inside the boot so I cleaned those too. afterwards.... no more misfire at same rpm and speed.

Somebody claims that their Engine torque dampener caused extra vibrations on the motor- and tripped the P0300 code. Once he removed the ETD the P0300 didnt' come back. How many of us that have the p0300 code issue have upgraded motor mounts or torque dampeners? I run the Powerflex front motor bushing. I never threw p0300 codes before with the powerflex and ECU+.. just after I installed my 272 cams.

I've been there done that.. 20k on my stockers.. went to NGK BPR7ES .026, swapped back to stockers.. to another new set of NGK BPR7ES.. no difference. I'm now playing with idle smoothing..
