probably dont happen to everybody, but i know for a fact it has happened to two of my budys that have mastangs and one with a expy, the first time it happened he was stumped it took an hour of spraying ether starter fluid around the compartment before i found were the leak was coming from, the Oring around the throttle blade and the body, on the mac it only uses one on the BBK it uses two. he only had it on for about a month before it happened on the stang, on the 5.4 it took over a year but he drives it like a grandpa.

 

Watch it! I'm a grandpa, and I know you won't keep up with me.

 

cheaper to replace and O ring than spend 200 bucks for a different throttle body.

u can also say that because the 5.4 has had so many recalls and major engine issues, that u shouldn't buy the 5.4 because it has problems... but hey thats just my observation

 

lets take it offroad and see who cant keep up pops
