anyone know what kind of car my engine came from??? oh and i have an idling problem.. i replaced my distibutor,spark plugs,wires about 6months ago and ever since then i have been experincing what my mechanic would call a "missfire" it kinda sounds like im shooting bullets out of my car..hahah. the idle jumps back and forth between 800and1000 any suggestions?the only thing i can think of is that i got the distibutor from Autozone and its for a D16a6.. but they are both 1.6L SOHC non-vetch engines.... would that be the problem?
