Disappointing Power

[BiGMaC]

Your symptom description sounds too similar to my experience to not mention.  My symptoms were acceleration going flat at the top of the gear. There was carryover into the next gear.  Before going into the dealership, I also noticed a sound coinciding with the performance flattening that sounded like a belt squeal.   The dealership duplicated the symptoms and claimed that the car thew a code for them. They explained that (their words) I had a vacuum leak at the high pressure fuel pump sensor, which caused an over boost condition. I'm thinking that the car pulled timing to protect itself. They told me that Ford did not use a clamp on the site of my leak. What they did was to trim the hose and add a clamp. Problem has not reoccurred and the car pulls strong to the top of gear and seems to leap as it hits the next gear. In normal driving I was unaware of the slowly developing issue. This may not be related to your problem but I could not help but see a similarity in your description of symptoms. Good luck finding your problem!

Well Tom you caught me being lazy. My description is strictly second hand as related to me by the service writer.  With the stuff I've been doing, I've had the engine cover off and I've had the MAP sensor on and off more times than I care to count, but I have not laid eyes on the site of the dealer installed non OE clamp. Though I've been curious, I have been to lazy to really search. I know where the fuel pump is under the rubber sound deadener.  I'll give a quick overview again this afternoon. The results of the dealer repair were rather dramatic.

Related to the O-Ring post from above:
IMPORTANT!
IF YOU ATTEMPT TO REPLACE THE ORING, DO NOT PULL THE THREADED BASE OUT OF THE CSS as I was originally instructed.
PUSH THE GROMET OUT OF THE BASE FROM THE TOP.


or if you have the right pics  / tools to get the oring over the base from above without having to remove the grommet, that's probably best.

*I've edited my above response to insure nobody pulls on the threaded base. ...I won't go into what happens when you do...just don't do it. 

EDIT: As an update, Tracy has been stellar (as usual) in his customer service, and assuring everything gets taken care of on my end.

I've been poking around looking for tracks the tech might have left behind as to which clamp he added and I'm just not certain. There is one clamp that is newer looking and a different color metal and so I took a picture of it for what ever it's worth. Sorry I can't be more definite than that!

In typical Larrylu fashion, you're on it!
We appreciate that!!

Some more good info...thanks guys.
I will be out of the country starting tomorrow for a week and a half so won't be reporting back.
But I will stay on it when I get back and let everyone know what I find.

Thought I would have time to look at that o-ring and check vacuum but got busy here at work...still trying.

Perfect Larry!   Thanks!

Speaking of clamps, watching Motorweek and Goss' Garage he talked specifically about clamps and when replacing them he recommends using OEM clamps but not to use the screw type clamp for a variety of reasons...just thought I'd throw that in since we are talking clamps.

[JimiJak]

Any update?

That is good to know...

The OE tension type clamps make me want to castrate myself.
The worm clamps I've never liked, for various reasons.
But, t-bolt clamps...
There's simply no substitute.

I would not use t-bolts on plastic tubing unless you want cracks and boost leaks.
