heres the problem, when I had the car it was a DX and I swaped it into a b16a2 motor and it started fine, but I had a p72 GSR ecu.. and in couple of months later the motor started acting up, it takes about 5 to 6 sec. to start up the car now..
Would you guys think its just a little minor problem i have like spark plug wires, and batt.. or is it the ecu im using on my SI. thanks

i doubt its the ecu, try replacing plugs, wires, cap, rotor
