Injector contribution codes when tuned
Ok so I have a quick question. So after a bunch of recent work on my truck I just put my street tune back on it and it threw a number 2 injector contribution code.
List of what has been done:
New injectors in 1 and 2
New tuned FICM
New injector harness
So I had my hold down on my number 1 injector come loose and I had to replace the o rings and copper washer. It works fine now but now I have a number 2 that misses just for a little bit right after it is started when the oil temp is between like 120-140.
My question is, could the injector not be torqued down properly and letting just a little fuel by the o ring when it's warm?
