when i replaced m drain plug i dropped the face of the hfcm and the heater core broke off so i didnt plug it back in...i start easier and feels like runs better..could this have any issues down the road?
I unplugged mine several years ago. I'm in FL so the cold weather is almost non-existent, but no issues to date. As mentioned, Ford didn't offer the heater in the later year models so I can't see this ever being a problem for you.
IIRC, Ford had some problems with those fuel heaters in the hfcm. I am pretty sure that after a lot of problems with the WIF light on my 04 Ex. the dealer disconected the heater and said there was a bulletin on doing this.:shrug:
