i got my truck back and it had a lag no problem. keep driving it figuring itll go away well it didnt so i just spent $$$101 on a throttle positioning sensor and am very happy my throttle response is alot faster but my laggs still there now im thinking possible fuel pressure or something the laggs only there when im going and really get on it. what should i do to go about this?
its a 2004 f150 4.6 with 172000 miles
