i changed the engine in my 91 accord to a 95 prelude dohc engine. i got it cranked and everything and it was smoking terribly bad so i put in a new set of plugs to see if that was the problem. then my ignition coil went out. i replaced it figuring that it was an old coil and that happens. well after i changed it i cranked the car up and the exhaust was still smoking and then my cars igntion coil went out again. that one was a brand new ignition coil. i think that the valve seals have something to do with the smoking but dont know what is causing the ignition coil to go out. thanks and please help me

 

mmm what plugs do you have in there?

 

do you have the right ecu in there? Did everything get wired right? Might want to double check the wiring since you are blowing your coils up.
