1994 FORD THUNDERBIRD LX keeps losing spark

1994 T-BIRD LX 4.6 V8 I KEEP LOSING SPARK ON CYLINDERS 2 AND 5 AND KEEP BLOWING THE IGNITION FUSE.. I FRIED ONE COIL PUT A NEW ONE IN AND IT RUNS FINE FOR ABOUT 10 MIN. THEN I LOSE CYLINDERS 2 AND 5 …



Are you getting a misfire code on cylinder 2 & 5? Or are you actually pulling the spark plug and seeing that it is not sparking on just those two coils?

These T-birds are known for the fuel injectors being stuck open. You can swap them around and see if the misfire follows the injectors or pull the plugs and cycle the key 10 times and see if gas comes out the spark plug hole.
