hey wassup i believe i have narrowed down my issue, i see that it is the fuel injector harness that is causing this problem. but, before i proceed to the next step in fixing this... is there a way how i can test out the wiring harness to see if that is actually the problem??

do you guys think that it is recommended that to rewire the whole harness from start to end? which ends at the ecu... or should i just clip the harness from the injector side out and re wire it with a new replacement?

btw, is there a such thing as a replacement harness for this?

 

i just got a code pulled up again today, i noticed i have 2 codes... p0204 and p0141

do you think that its the o2 sensor that is causing my injector to malfunction? or is it the injectors?

 

took my car to the dealership today to see what they can do to diagnose the problem. came out to be my resistor box for cylinder #4 that is not working.

part is not available anywhere here, so its got to be special ordered in japan... going to take 30-45 days to arrive.
