I have a cylinder 6 misfire code. have replaced cop, plug and injector but still have the problem. Going to check compression and see if that is proper
JA: Have you seen the misfire code before? Has the car been stalling?
Customer: no it doesn't stall and I bought the truck with the code. When it gets above about 1600 rpm the engine
seems to smooth right out but below that it runs rough.
JA: What is the model/year of your Ford?
Customer: 1999 F150 with the 5.4
JA: Are you fixing your F150 yourself? What have you tried so far?
Customer: I've been fixing it myself so far. As I said, I replaced the coil pack and plug as well as the injeclor. It performs some better since I replaced the injector but the miss is still there
JA: Anything else you want the mechanic to know before I connect you?
Customer: I don't think so
