engine will start with no codes sometimes when cold takes longer cranking to start. Upon hard accelerating for 2 to 3 seconds engine starts to misfire. checking with scan tool shows only p0302 code. with scan tool still hooked up clearing codes makes engine run normally untill hard or slightly more than medium acceleration is used. I have replaced plugs, wires, ecm, fuel pump, and have even swapped coils. Car had cat removed before I got car, but i driven it for 70000 mi with no other problems other than timing belt replacement 40000 mi ago any ideas ?
