    My 2010 has been running rough and now I've got a check engine light. I put my code reader on and it says coils 1 & 2 are misfiring, so I need to replace the coils. I see lots of options on Amazon for a low price but would rather get a good part even if it costs a little more. Does anybody have a suggestion for a place to buy quality aftermarket ignition coils?

    To confirm the problem is the coils, swap cylinder # 1 & 2 with # 3 & 4.

    I got mine from Autozone for $240 plus taxes came to $258.59

    They got them for $235 right now.

    Lifetime warranty and if you ever have one that fails just go into the local Autozone and switch the bad one out right there.

    I carry the tools I need in the car for that reason, I can go anywhere and if they go bad I just find an Autozone.

    You cant go wrong and call it a day.

    That price is for all four but as sugested do the switch around to confirm its the coils.

    Otherwise if the misfires still happen on 1 and 2 you have a bad headgasket. 20241005_165655.jpeg 20241005_165814.jpeg

    Does that mean the codes were P0351 and P0352?

    It's always more helpful to tell us what the codes are (we can look up what they mean), and not just give some version of what they might mean and make us try to remember what codes might mean that.

    If you had the P035x codes, those are about the ignition feedback (IGF) signals the coils send back to the ECM. The codes could mean the coils are bad, but it's never a bad idea to rule out some simple issue with the wiring in the IGF circuit.
