i already asked this a couple days ago but the problem is still around, so my car has been being wierd lately. sometimes it happens right when i start up but usually whenever it gets to operating temp or has been running for about 5 mins, it starts to chug and the tach dances. it feels like i am running on 4 cylinders. i looked at some old posts and i changed the fuel filter, fuel pressure regulator (huge PITA), cam sensor, and crankshaft sensor. and the problem is still around. i am going to go and try to clean up the DIS module a bit and see what happens. but can anyone think of anything that might still be wrong? some ideas i got from you guys are the harmonic balancer or DIS module. i dont want to replace something else that probably still works. please help! thanks
