I made a post earlier about plugs I swapped the bad ones and whiles it’s a lot better, I still have a misfire but only at idle runs perfect under load. It threw A p0300 but after a maf clean and air filter change it went away and only misses at idle now. I’ve done everything I can think of maf,filters,plugs, coils. Tuner says the tune looks perfect no fueling issues. Any ideas ? I still have stock IMRCS I’ve been thinking of locking out still new to the platform.
