White 96LT1

iTrader: (4)

ok, i went to the carwash yesterday and then my car started running like crap. at idle it is perfect for about 3 minutes. then it sounds like the timing just changes dramatically. and it just starts cutting out. it runs rough and the rpms start cutting out. then when i drove it i would be staying steadily in the throttle then the trottle just jumps and does all kinds of weird things.at first i got a check engine light. the code was the misfiring code (p0300). so i read my book and i replaced my coil. but now the code doesnt show up anymore.
