sup IA got a question, i was driving one day and all ofa sudden it started running on 3 cylinders out of nowere so i parked it at home.while running i checked for spark and it was getting it, so turned car off and took plug out, plug was good so im thinking my injector failed. how hard is it to replace one of these and how much would a new one and o-ring cost?

are you sure its the injector and not a bag spark plug ? If so, they are easy to replace, I would just grab one from a local junk yard and try that, before buying a new one.....

naw the plugs are good. ive narroed it down to the injector, i tried taking the connector off but it looks like i need a special tool or something....any idea?
