Has anyone ever had a problem with there throttle body on there xf efi engines?..For the last 2 days while in 4th gear or while driving slowly the car would " accelerate and then slow down then accelerate " like it had a life of its own. So this afternoon i took the hose " TUBING" off to the throttle body to the AFM and cleaned it out with CARBY CLEANER and it fixed the problem. What did i fix????

sounds like you just cleaned out the idle bypass valve carby cleaner i swear by it

Kool, just by the by, do the throttle body get worn by wear?

not really it has 1 moving part

Ok just wondered why when i turn the screw in the throttle body nothing happens...
