CEL p0301 back again...

[desertmike680]

Just got my car back from Mazda yesterday, in which they replaced the fouled spark plug and coil pack from cylinder 1, obviously causing the misfire CEL. Hence, the CEL is back not even 24 hours later. Love it. So, they will get another call tomorrow.

Question though. That new plug they put in is gapped at .032 and I re gapped the other 3 plugs at .024 3 weeks ago. So I have cylinder 1 at .032 and the other 3 cylinders at .025. Would that cause the CEL to come back? Or does our Speed 6 really suck ass for misfiring issues.

Thanks.

not saying it caused the issue but I would think all 4 plugs would need to be gapped the same if not relatively close.
