Question about 2007 Mazda MPV
2004 Mazda MPV 60,000 miles. Took van to Autozone to check the Code. Code shows #5 cylinder misfire. Changed spark plugs. Problem went away. Now its back. On cold days slight rough idle at 1st start up. No engine light. Drove van 10 miles and engine light came on and was flashing. Parked van 2 hours. Drove 10 miles back and no problems. Can I move the coil pack to see if problem follows? Thanks.
I have a corolla and had #4 cylinder misfire also diagnosed at autozone. After changing the spark plugs, problem persisted, along with the same error code, so they recommended changing the spark plug wires, and that is what fixed it. I would have changed the rotor cap too, but was low on dough. Glad that was not the problem.

Yes, it's around $470 with tax at the dealer for all 6 coils & secondary coils, the plug wire equivalent. Look for a better price online. Once you get the hang of removing/replacing the intake plenum, it's not that hard. I replaced all 6 at 70k miles and now she's running great again.

Time to change the coils. I'd replace them all as they will start to go bad one by one and continue to give you misfires. The three that are fun to get to are 1,2,3 and you have to remove the intake plenum to change them.
