hi guys.. my fd seems to be running on one rotor. the car does not smoke at all so im thinking a couple things.... spark plug maybe fouled out? injector? coil went bad? any other suggestions for me to check? also if the motor was blown the car would probably smoke right? thanks for the help fellas

 

Pull plugs and check coloration. Look for signs of "coolant". If car has been running fine up to this point (no coolant issues), I'd look to the coils first, then wires. Mine never smoked prior to losing my coolant seals a few years back.

 

thank you.. forgot to mention motor was rebuilt less then 700 miles ago.. im going to start with the coils, wires, plugs and then take it from there

 

Compression test it.
