i have searched but cant pinpoint the problem....i have a b20 vtec swap with a gsr head and b20z block in my 97 coupe with gsr obd2 ecu. The swap was done a week ago and ever since it has been bogging as soon as i let off the clutch and throughout the powerband. A couple of days ago i switched my spark plug wires from the sohc wires to gsr oem wires and the problem went away for about three days....until yesterday a hose was leaking coolant and since i got that fixed the problem has returned. Anybody have any idea what could be causing the bogging?

 

any cel's?
hows your fuel pressure?
checked your timing?
a simple search would have lead you to these questions...answer em for us and we might be able to help

 

the person who did the swap said the timing is right...i do i cel's but cant drive the car to check them, yea its that bad. Im gona have to buy a fuel pressure regulator to check the fuel pressure. i was thinkin maybe it was a sensor?
