I just recently swaped a b16a2 into my cx i was forced to use a p72 with the motor because the ecu street imports sent me was junk..the car runs fine but when i first start it in the morning it revs and idles like it would eny cold morning but only for a few seconds at witch point it slowly dies..i can give it gas very gradualy but to much gas and it will die. When i can get it to rev it sounds as though it's running on only a few cylinders....it dose this untill the car is warmed up...eny ideas on what this could be? thanks

 

enybody?...little help here

 

did you check the plugs?
how's the commpression?
fuel pressure?
any vacum leaks?
good luck
