Hello everyone I'm needing help with an issue I've been having for quite some time. My truck is a 2005 f150 xlt 5.4 3v with 134k and when I'm at a dead stop my truck takes off good but then it cuts a little power smoothly, it's enough to feel it come back on and acceleration is normal. Sometimes the power won't come back and I have to floor it and then it downshifts and accelerates normally. Ive had my spark plugs just changed, put in a k&n air filter, trans oil and filter change, and a reflash. My truck also has problems with power on the highway to pass. ANY HELP WILL BE AWESOME AND THANKS!!!
