Service Engine soon light is ON on my 2004 Ford Explorer /142K miles. ODBII error codes are P0300, P0302, P0312 and P0316. Could anyone please let me know what could be wrong and what should be the go forward plan?
I don't show a listing for code 316, and I really doubt you have a 12 cylinder engine! The most common cause of misfires is spark plugs, and spark plug wires and / or ignition coils, depending on which engine you have. Start with those if they haven't been replaced in a long time.

Thank you. I have warranty on the car as I just bought it 10 back from a car dealer. I am planning to get this checked out and will post back results soon for everyone else knowledge.
