thanks I'll check more this weekend

This post is an update from yesterday. Car dies while driving on heavy acceleration. It can be restarted [runs poorly for 1 to 2 minutes], then runs ok, sets check eng. code po303, misfire cylinder 3. Plugs [not to tight, ngk], wires and fuel filter new, coil pack swapped with one from junkyard. Without replacing everthing at once I would like to prioritize the possible faults. Injectors? MAF? TPS? or replacing the plugs and wires again. Thanks again for your help. Joe

Yes, the fuel filter is new. The car restarts even while coasting and can be driven to higher speeds unless you have to go heavy on the pedal. Thanks for your reply. I'll also look at the fuel pressure reg today

I'll recheck them, thanks.

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
