5.4 Hesitation under acceleration
Hi all...I have a 2006 F150 Harley with about 60,000 miles on it. Since I have owned this truck, it falls on its face under heavy acceleration such as passing. The truck is bone stock with factory intake.
Runs great otherwise during normal driving.
No codes thrown ever.
Remedies I've tried:
New fuel filter
Fuel system serviced at dealer
Dealer said PCM needed to be reflashed,which they did-this did nothing whatsoever
Checked and rechecked for vacuum leaks-none found
I otherwise love this truck and would appreciate any help.
