ok, have just drop in my jdm d15b motor and trans into my 96 dx coupe. i go to start it up and it idles and bogs. i am using the p28 ecu... am i running too rich here? and also i have somewhat of a white ish smoke coming out of my exhuast, could my headgasket be bad? i think i might need to change my head gasket? well, anything would help guys and gals... thanks in advance

 

did you put new plugs in it ? did you do a compression test ?

 

If the car hasn't been started in a while, a decent amount of white smoke is normal. If it continues after the car is warmed up or if it smells sweet, you probably have a problem with the head gasket.

 

well in my opinion go to check out your oil dipstick and see if it is somewhat milky this is a good way to check and see if your headgasket is the problem also does it overheat.

another would be is timing problem it has a big impact on how u do things could u be off by 1 or 2 teeths cam timing or ignition timing did the motor come as a whole or did you put that timing belt on there with less exp
