multiple misfires? I have a 2000 honda civic ex and it was fine one minute and later on in the day it idled rough and the whole car shakes. The exhaust does not sound the same almost sounds like a motorcycle exhaust. The check engine light is also flashing. I took the car to autozone and they told me I had multiple misfires on all 4 cylinders. code P0300 The car just had a tune up last year. Any ideas? My buddy said something about a button cap and rotor? I've also heard it might be the heated oxygen sensor. Any ideas?? Thanks a much!
