P0304 Ford - 1997 Crown Victoria

Question

I changed the spark plug, the wire is new, but engine coolant was around the plug area last time. I'm lost on what to do besides junk the car.

Answer 1

if you are getting spark to the spark plug, you should check the fuel injector or try to swap the fuel injectors and see if the code changes.

or check the resistance on the fuel injector on cylinder 4
