2003 F550 Backfiring?
This F 550 (95k miles) wasn't used much this winter but was started periodically.
We started it the other day and it appeared to struggle a little to turn over.
When it finally started there is banging/backfiring noise coming from the engine.
It almost sounds like a gas engine with a spark plug removed.
Can't figure it out, it was fine when we parked it a week ago
Thanks,
VC

I have no idea, but I will bump this back to the top so that you have a better chance of one of our 6.0L gurus seeing it...and the shameless tag so I can follow up on the thread, as it has me a bit curious.

I checked all the hoses they appear to be ok. I did notice when I put my hand on the intake I could feel the banging. Someone suggested a sticky valve. It was recommended to try to fog the engine thru the intake with mystery oil to maybe free it up.
