im trying to complete my 96 hx swap....i put in a b18c5 motor with a first gen jdm b16 head....im using hx harness and an obd2a p72 gsr ecu...i am experiencing some hesitation and sputtering when i give it gas.....can't figure out the problem....im thinking it might be timing but i havent checked it with a timing gun yet...just wanted some suggestions on wut else might cause the problem....

 

not enough fuel but check your timing first.

 

any cel?

 

only cel is primary o2 heater and secondary o2 heater
