In addition, the fuel system recall, ford states that there isn't one on my vehicle, however, my vechicle displays the same symptoms described under recall 04v421000 and the continuous check engine light. I have had all sensors repaired that came up in engine diagnostic testing . According to last test done, reads fuel is running lean but can't repair because no code appears for that to show where problem lies. I have had fuel system flushed to help remedy problem. Still having issues.

My 1999 cougar was taken in for a tune up recently. The spark plugs were replaced with new ones. Approximately 3 weeks later one of them blew because ford made a defective spark plug thread. Now I cannot get it fixed because a ford specialist must go through the engine to repair and it will cost $1300.00. I thought getting a tune up was a good thing!
