I bought the '04 Thunderbird new and had it "tuned" at the 100,000mile service. New plugs, etc. 70 miles later the car went into limp mode. All COPs replaced but diagnostic showed all COPs non functioning. Computer module sent to Ford and it tested ok, put back in the car, more tinkering and now only cylinder #3 is not firing and they are stuck. All believe it is electrical. Some have suggested replacing the wiring harness but there are none available in the US. Others have suggested an old time mechanic to find the electrical glitch and the Ford dealer has said he will not charge for the work done if the car doesn't run. They have checked, or say they have, for corroded parts and injection ports. They are receptive to any suggestions and not afraid to ask for help. I am prepared to take the car to one of the old time mechanics with whom I have spoken who claims to be anxious to look into the mystery since it is what he loves about repairs the most. What do you think?
have the same problem?
