My wifes' car recently has a mind of it's own. It runs fine on easy acceleration, but 1 time out of 5 on heavy acceleration the engine bogs down and dies. after pulling over the car starts back up and runs seeminglly fine, until it dies again on increased throttle. Recently new ngk plugs, wires, and filters. AutoZone read the check engine code and they said misfire between cylinders 1, 2, and 3. Also on heavy acceleration a/t oil temp. lights up on dash. Level is good and car shifts fine. We are afraid to take the car on highway. Thanks in advance, Joe
