I have a 1991 Acura Integra, only 140,000 miles. My car is running on 3 cylinders and oil is leaking from the oil drain plug. My friend, he's pretty good mechanic says to change the spark plugs. I found the last spark plug wasn't firing. After I changed all the plugs, same problem. Next, he says it could be the Fuel Injectors. I ordered some Venom Injectors and replaced them. Still the same problem. N/E body know what could be the problem? Thanx....

 

check distributor?

 

have you taken a compression test yet?

 

coil, wires, distributer,

 

I think I'm going to take the car for a compression test. Well I live 5 minutes from King Motorsports. So, going let them check it out. I'll know for sure. My friend says it not good driving it, I'm dad's gheto ride for now. Thanx Yall...

 

I'd try wires next.

 

The compression would have nothing to do with the car only firing on 3 plugs...I would change the wires and then check the coil.

 

Are you getting any white or black smoke out of your exhaust? If not it's most likely going to be electrical.

 

Steal some Mugen stuff while you're there
