Runs like crap again P0300 code-hemi 5.7
I have read so many different remedies for this issue on many forums and posts, but I will put injector cleaner in. BTW I have been running Chevron 91 for a yr now. Thanks for advice and the welcome note!- silversides04

I used the regular plugs not platinum, the stealership put them in less than 5K ago.- silversides04

Runs like crap again P0300 code-hemi 5.7
I just got this P0300 code 2 days ago(the first time was 3 months ago and they said I needed new plugs so I got it done and CEL disapeared until 3 days ago). Today on a cold start she runs OK for 2-3 minutes and then wham! it runs like crap. 3 days ago it started running very bad while I was 50...- silversides04
