2005 F-150 XLT 5.4: Hesitation when hard accelerating.
When I accelerate hard, for example getting on the highway and giving it gas hard, it hesitates to go then it will go and hesitate again. It does this about 3-4 times and then goes without an issue. A buddy of mine suggested it may be clogged injectors. I tried a fuel system cleaner and high grade gas for a tank, but no diffenerce. Any suggestions?
replace the fuel filter...............
That's an early sign of a plugged catalytic converter
Clean out carb and air intake
