check engine light at 1500 miles code P0300

[Shadowblks550]

Had this baby pop last night while driving, hooked the reader up and had 3 P0300 misfire random codes. Only mods are Mbrp xpipe and axel backs. Anyone familiar with the cause of this code on a brand new 19 gt. Mods were installed at 1100 miles and the car now has 1500. Got a appointment at ford next week to find out and hopefully they don’t try to blame my xpipe and axel backs. The car still runs fine and doesn’t seem to sound like it’s miss firing at all. Thanks for any input on the matter.

That's just a general misfire code. Don't think x pipe and mufflers would cause that. Could be about a million different things including spark plugs, bad gas causing a backfire, etc. But don't think it's due to the mods.

When you take it to the dealer mention misfire monitor correction program within the IDS. Could be just a re-learn issue

Update, ford ordered me a new intake manifold. Said it’s a faulty imrc issue. Crazy that a brand new car needs a new manifold so soon.
