I have an 06 4.0 with an Xchareger on it and having a problem with the car hiccupping (only way to describe it) from a standing start. It has only done it a few times and only when accelerating from a stop.Otherwise no problem.
I was told there was a TSB posted here somewhere about the fuel pump. Anyone know where I can view it???

any other suggestions appreciated

my car does this as well but only randomly after being on the highway for 2+ hours when I come to my first stop (usually at the end of the exit ramp) then when I try to accelerate it will hiccup before it takes off.

Jim,Go to 2005+GT tech and at the top you scroll down and you'll see the S197 TSb's listed.Yes,if you have the stock fuel pump,they do have a tendency to surge and go flat at times.I had mine changed with warranty to a new GT500 fuel pump at the dealership.Other than this problem,how you been doing lately?

i need to get this fixed on mine too. same exact problem. after long trips bubble build up in the line, and when you stop and let it idle at a light right off the ramp or something, it chokes on the bubbles for a slip second. i noticed it a few months ago when i drove across the state for a meeting. getting that new pump, hopefully a gt500 pump like okcreferee did will stabilize your fuel pressure more evenly and stop the hiccups. especially since youre f/i. do you have a fuel pressure gauge? boost gauge? wideband a/f gauge?

[mrjimmy]

I have the vacuum/ boost gauge and a fuel air to be installed soon. Sounds like a new fuel pump in the future to.

yea, cant be too careful with fuel pressure. hey how/where did you get your valve covers painted? dont mean to get off topic but those are gorgeous, and its what iv wanted to do for a long time. lmk

[mrjimmy]

did you guys pay $700 for a GT500 pump????

under warranty im guessing noone paid...just kinda nudge your ford tech at the dealer
