I think it's my fuel pump but I'm not sure?
I have a 99 explorer and recently
it's been stuttering when I try giving it gas.
And a slight knock every once and awhile
When is the last time you changed the fuel filter? My daughter's 2003 experienced the same problem a few months ago. She had never changed the fuel filter, I changed it and all was ok. For info purposes, when I removed the old filter and turned it over to drain the gas, the fuel that came out was black.
