need help guys
im a newbie and hope u guys can figure this one out. i have a 99 ford f-150 5.4 with 140,000 and recently it started hesitating and it gets worst when its under a load for example if im driving down the interstate cruising its not that bad but when i get to an incline it starts hesitating bad. i have no engine codes i changed the fuel filter and it was clogged and put new k&n on it. ive read somthing bout clogged throttle bodie i thought it might be the fuel pump.
