Ok guys, quick question. I recently replaced the plugs in my 03 Mach one and all of a sudden I am throwing 2 codes. P0330 and P1151. I switched from NGK TR6 Iridiums to TR6 Copper plugs (what I had in the garage. The car has gone literally 3 miles since the swap and had no CEL codes showing prior to that. Any chance switching back to the Iridiums will fix this?
