- Engine misses throughout driving speed range
It first started with code P0307 misfire and went away. Next time engine started code P0301 misfire and went away. The next time the engine was started code P0300 multiple engine misfire and is always there now. Checked plugs ( AC 41-932 ) the gap was about .056 . We have only put 3K on the car and have had it for about 2yrs. The car always ran supper. I have not done anything to the car except change the oil. I have and AUTOXRAY EZ-SCAN 5000 that I read the codes with.
Thanks Warren
