If it's a 2.9 then...... altogether now.
Throttle Pot.
Is it hestitating when you put your foot down if so then the TP has to be a prime candidate. They are notorious for failing. Their job is to read what your right foot is doing and tell the ECU to put in the appropriate fuel. The tracks on them waer over time and lead to spurious readings which confuse the hell out of the ECU.

Your freindly Ford dealer can help. I don't believe they are repairable. I think Ford now only sell the 'gold contact' version which is supposed to be more reliable, but you need to get the new plug and wiring that goes with it. This needs to be put in place of the existing one, and it needs to be connected differently. I can't remember how it goes now, but if you do a search on the forum for throttle pot there are several posts on how to connect it up. The part number is on the parts guide, on here.
Godd luck.

mart, i had this problem in my old porsche.....under load, ie: as i went to overtake!!! the car just sluttered. Very dangerous. I found by looking at the car in the dark i could see a very small spark every 2 mins or so between the fuel injector and the lead.
Replaced leads and injector and the problem went. Might be worth a try just having the car in the dark to see if you can see any random shorts. This type of problem is very frustrating i know cos it can be any number of things breaking down.

Yes
You should have the throttle pot which is usually a black plastic thingy attached to the other end of the thottle spindle that passes through the plenum chamber. Also nearby is the idle speed control valve which is like a horizontally mounted cylinder. Both of these should be connected up to the loom.
Have a look in the Bible on page 58.
