I have a KOER P0302 misfire code. Did not happen until I had plugs and wires replaced (bad move). New coil pack also replaced. Injectors cleaned when plugs and wires replaced. Mechanic can find nothing to cause misfire. Takes about 1 week for Check Engine light to come on after being reset.
Do you
have the same problem?

Hi golfguy54, Welcome to 2carpros and TY for the donation

Cyl no.2 misfire-check the sparkplug/compression and injector for this cylinder-then report back-try erasing the code again

I have not had a chance to do a compression check but what I did notice that makes no sense is that when A/C is on the misfre/stumble at idle disappears.

I was also going to switch the plug with another one and try another wire on that cylinder to see if it makes any difference.
