I have a Ford F150 XL with a 4.6 W engine the floor got washed and now it boggs down on acceleration it is a 2009.I have replaced the acceleraton pedal and throttle body but still boggs down

I'd check MAP sensor vacuum hose and connections, plus replace the Throttle Positon sensor. You have done the spark plugs and wiring,right? Look for any vacuum leaks. Check that the EGR sensor is working also. don-ohio

Catalytic converter is likely plugged.

No freeby advice here...

cluctch is not properly adjusted or they didn't replace the pressure plate?

sounds like you need a tune up or a coil is bad

either fuel filter or fuel pump...replace filter since its cheaper. 6-12 dollars at autozone

vacuum advance working ? do manuel check with cap and rotor button off and see if it's moving. chris

sound like throttle position sensor.

sound's like your front diff is seized :( could be wrong but id check your front diff fluid for level, color and any metal shaving's as they will be a good start. hope this helped.
