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.
Thanks but my MPV does not have plug wires. It has a coil pack on top of every spark plug. I don't know if the coil pack could be Intermittent. Thanks but my MPV does not have plug wires. It has a coil pack on top of every spark plug. I don't know if the coil pack could be

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.

I'd check #1 spark plug.
Usually a misfire code "fix" is a spark plug, spark plug wire, or a coil pack / distributor.
Keeping it simple...I'd go with the spark plug first and then look at the condition of the wires.
A Cylinder Misfire Code is usually a very simple fix. Most of the time it just means you may need to change the spark plugs especially if you haven't changed them in a long time, you may have a clogged fuel injector from having a dirty fuel filter. The least expensive thing you can do right now is to replace all of the spark plugs first and than go from there.
may have hair line crack in coil,,or bad wire,,spay wire while running with a water missed spray bottle,,& see if u can make it misfire,,start at spark plug & work ur way up,if it starts to misfire when u get to the coil,,u will no with part to replace,,hope it helped,,
Cylinder 4 is misfiring. Take it to a mechanic and have them take a look at it. Im guessing its the distributor, Spark plug, or spark plug wire on cylinder 4
yes i would change the plug wires , you can take a spray bottal with water and spray that wire, and if it starts to run real bad then it is shorting out, you may also have a injector going bad you can test this buy puting a ohms meter on it and ck the ohms it should read the same or close to the same as the other if not it will need replaced
Code P0301 is a generic OBD Code for Misfire. It also indicates you have a misfire in the #1 Cylinder. I would start by checking the plug wire to make sure its clean and on all the way (at the coil as well). Then if that doesnt help I would pull the plug out and check the condition of the spark plug. hopefully this will give you some direction. Thanks for Using FixYa!
