    Default Ford Focus diesel, problem with rev's dying

    When I drive my 1999 Focus diesel after a short time my glow plug warning light comes on & although the engine is running & all the electrics are working you cannot get any rev's, but the moment you switch the engine of & start the ignition all's fine for another short time the same things happen. It's occuring at a shorter time as time goes by.

    Anyone else suffering this & could give me a clue?

    I have a ford focus tddi 90ps v reg with about 65000 on the clock and I have the same problem as yourself. my wife rang me this morning with the same symtoms on her car.
    I had the air intake pipes off the weekend because it is smoking quite bad (black smoke) when you accelerate hard, the intake pipe by the egr valve was caked with oily sludge so i cleaned it out the best i can and took it for a run, it seemed better, i just hope i havent damaged anything. i will have a look at it tonight and let you know if i find anything.

    i have found with further investigation that if you keep blipping the accelerator and not let the car idol the glow plug light will not flash and the car will run fine, on first start in the mornings the car smokes quiet badly (blue smoke) but as soon as i take it off the drive it is fine. i have rang my local ford dealer and they were no help (bring it in so we can keep throwing parts at it till it works and charge you 80 quid a sensor ha ha) has any one out there had this problem and fixed it please let me know, thanks

    did you replace the accelerator box or can you actually repair these with a bit of contact cleaner?
    i have been told that the ECU measures the resistance of the glow plugs and if its too high it will cause the glow plug lamp to flash. so i will be fitting them hopefully the weekend and i will let you know.

    This has got to be a stock fault and it's resolution known. I havn't replaced anything yet, I'm trying to get hold of some diagrams /manual first. are you replacing the heater plugs or can they be cleaned off? . good luck.

    I've just looked at another site ffoc.co.uk. this fault is almost certainly a faulty pedal unit (I think the pot is within) three bolts and a socket to replace. please let me know if it works.

    just replaced the pedal unit 70 from dealer the replacement looks different but works fine. No panels or carpets to remove, 3 nuts M10 and the unit comes clear then release plug. I stripped the old unit and all thats inside is a plastic film with carbon tracks and a wiper to sweep across (same idea as a scalectric contoller) and the tracks were clearly worn through the carbon track and the film "holes", also i had to cut of a mounting lug on the pedal unit, this is used for other models. Im off for a good run the weekend should prove it....hu..hooo!..... tell us if it's good for you.

    i cleaned the contacts on the glow plugs the week end and had no complaints as yet. basically slackened the nuts, sprayed with duck oil and tightened them back up, i will keep you posted on any problems.
