I have a 2003 Ford Explorer Sport Trac with 68,000 miles. I'm thinking
I have a fuel related problem. Idles fine and will accelerate normally
up to 3,000 rpm. After that, runs rough and won't accelerate. Let off
throttle and idles normally again. So I replaced fuel filter.....no
luck.

Now I'm thinking fuel pump.

Are there other things that I should be looking at??? No codes
flashing....nothing. Maybe a sensor???


Appreciate any ideas before going to the dealer.
