ok my 99 gsr swap in my 1995 coupe EJ1 EX is missing fuel (i think) or spark(i also think) one of those two i cant seem to find whats wrong with it, I already cahnge fuel filter, tigthen b&M gauge,new gsr fuel pump with strainer, new spark plugs, check for leaks, check vacuum,
pvc valva,ok next
new rotor and distributor cap( do u recommend i go external coil), could it be my distributor?
it only backfires and loses power for a second(if i gun it power comes back a little) but drives fine all the time.

i'm running out of options
thanks for your help/

do hondas have a fuel relay?
would that make my car miss through the driving range?

 

recheck your ECU

I bet its your ECU dude

 

its not your ecu. Its a sensor. Could be a lazy oxygen sensor, i supose you dont have acess to an ociliscope if you were closer to me i could come check it out for you...


this is what i would check in succession

1 Battery voltage (im a by the book guy)
2 Oxygen sensor (get the wave pattern when the car goes into closed loop, you should see the o2 cycle extremely quickly, 8-10 times per second)
3 ECT test the voltage of this sensor as your car is warming up, as the sensor gets hotter, the voltage should drop

 

I would say that you have a bad oxygen sensor. Unplug it and see if the problem goes away.
