i got stage 2 mhd with one step colder spark plugs gapped to 0.022” and catless down pipe, DCI and chargepipe. Im getting an engine light and stuttering when i try w.ot. but it seems to not happen all the time. I’m not getting limp mode and sometimes the engine light goes away and the misfire goes away if i keep driving. codes are cylinder 5 misfire and i swapped out that ignition coil for a different one i had (used). Car drives great with lots of power when just driving normal and the occasional half throttle blip. Any ideas? lmk if i make sense or not too lol.
