Could be the TPS (throttle position sensor ) , check wiring / connector also.

Sounds like the throttle pedal at fault

It could be any number of sensor,s at fault but advise main dealer diagnostic to get to the root of the problem as your tool probably is generic and not able to work as the main dealer kit does.

Thanks for all the rplies, just a quick update - I got to work with no problems last night and back home again this morning with no problems so don't no what to do, I am carrying my diagnostic machine with me now so if it does happen again i can put it on while the fault is there and see if it comes up with anything.

I also own a ford fiesta van 2008 model TDCI.I have had this exact problem 3 times now, and each time i've had to be towed home. I took it to my local garage, who have replaced the throttle pedal and sensor. Every time its happened, the powertrain engine fault light shows which looks like an exclamation mark in a squiggly orange circle. The van run fine for 2 weeks, and a few days exactly the same problem again, going along nicely until all of a sudden the revs go down to the engine idle speed. I've taken it to an official ford dealer who've run it thorugh their diagnostics, and the only fault they could find was with the EGR sensor on the exhaust. So they've disconnected this to see if it runs for more than 2 weeks, only trouble is, I could break down again! Will keep posting to see how that goes. If anyone has any suggestions as to what else it may be would be greatly appreciated, thanks.

When it went into ford last week they said no update was available. The only thing they could do was to unplug the EGR sensor and see how it goes. So far (touch wood) it's been running fine since they've done that.

Thanks again for all the replys, just a quick update, its been fine since that first day it happened, must admit i have only been back and forth to work each day which is 12 miles each way so don't no what it would be like on a longer run, the only thing i done was topped up the engine oil as it was showing low on the dip stick can't see that had anything to do with the problem but its all i did and it hasn't happened again (touch wood. Just a bit more info, when it happened the light that looks like a cog with an ! in the middle did flash and also while i was trying to restart it the oil light flickered thats what made me check the oil. will let you know if it happens again.

I had the same problem sent off and no revs this carried on for 5 weeks in and out of the garage they fitted a new coil pack ,lead's , plug's and still no change, so back on the diagnostic machine it went and a new throttle pedal was fitted still no change so at this after spending over 3 hundred or more on it i was about to give up and get rid until at the garage an apprentice had a go,and low and behold he FIXED it,it was carbon on the electrodes 15 min it took him,the diagnostic machine would only say peddle fault, so have the garage check all the electrode points first it may save a lot of time and money, it may not be on your's but worth a go
