i just pulled out my injectors to do my head gasket and all the injecors came out easily eaxecpt for number 3, so when i got it out i noticed that it had alot of carbon build up on the injecor itself, the part that sits into the head and also the tip. could it be that the copper washer wasnt sealing? or could it be a bad injector? the injectors are less than a year old they are from jkidd theyre 5x.016s. thanks guys
