HELP! 08 f150 bogs down
Hello, I have a 08 f150 with 100000miles and just recently it started to bog down under load, I have changed plugs (with oem) o2 sensors (oem)fuel filter, cops, maf,
I have ran 4 tanks of gas threw it now from place i know the fuel is good, an still acts weird. I can be goin down the road and it seems like i hit a head wind when i pull trailor an when i start giving more throttle it does nothing till i hit down shift trigger.
Any ideas would be appreciated.

I take it you have no code. Could be the throttlebody sticking. My son had the same problem on his 2006 5.4. It finally threw a code and it was indeed the throttle body hanging up and not reacting to the pedal action. It has been an issue on some 5.4's especially in cold climates which I don't believe you reside in but it may not be a true factor.
