i have a 93 civic cx with a b18c1. i changed the motor harness to a gsr motor harness but now the car is idiling funny and the motor is choppy (shaking in a weird manner) . everything is plugged in correct . im also throwing a code 16 (bad fuel injector it says) but i changed them and its still the same. what could be the problem?

 

why not switch back to original harness?

 

it was fried so i had to change it.

 

oh. heres how i would check:

while car is running, remove each plug wire one at a time. if you remove one and it doesnt change the idle, troubleshoot that individual injector wire by checking the continuity from the ecu. just an idea.

 

the fourth plug furthest from the battery does not change the idle.

did you ground out the injectors in a good spot? there is a ground wire for them, if it's not grounded right it'll act up.

 

wheres the ground?
