    Advice really needed..Throttle sticking on..2.8 V6, auto, Weber 38dgas

    Hi all, Advice needed..my throttle is sticking on weber 38dgas on ford 2.8 V6 fitted in my A. The car is an auto C3. This has happened 3 times now , so I have changed the cable for a new one and made sure the pedal is workig fine. I did this work last week and test drove the rod yesterday, with hard standing starts using up to full throttle and all gear changes, I also drove normally as well. Everything seemed fine, throttle wasnt binding and released fine. It felt much better than the previous old cable, just firmer as I was now using the original equipment return spring, the previous was like a biro spring...
    So tonight I thiought all was well untill I was going up hill at a steady pace, the rod was in top gear and on half throttle or so, as I backed off she stuck on again, (this puts the ****s up you in an auto) I pulled over and she came off with a couple of firm blips of the throttle. In the 3 times this has now happened its been on the same sort of 1/2 to 3/4 throttle.
    I cant seem to replicate this in the garage when fiddling with the throttle. Engine running or not.
    Engine and gearbox seem perfectly fine.

    ....Any help would be appreciated....thanks RR.

    Model A

    2.8 V6 automatic C3.

    Check you have an earth strap on the engine ...honest . I had that problem many years ago , it was using the throttle cable as an earth cable when starting and causing it to fray inside.

    Also check under the dash and make sure nothing is catching on the top of the accelerator. As it only happens when you are driving make sure you aren't pushing the carpet or something up to stop the pedal returning.

    thanks for reply kapri,

    No problems under dash., no fouling, etc.... the cable is new, just fitted last week. because I thought it was the problem,

    Am interested in the earth strap thing ?

    would there still be an earth stap problem when a new cable is fitted.

    could it be something loose or over tight in the carb itself.

    If your earth strap is there but broken when you start the car you will use the cable as the earth and that makes it heat up and can melt the cable or liner making it stick.
    When the car is running it will be using the cable for all engine earth functions as well hence not being able to replicate in garage ticking over.

    There shouldn't be any bind in a new carb . is it auto ? If so check smooth operation of kickdown cable to make sure that is returning ok and not bunching up on return and stopping the throttle.

    .
    Yes, the new cable would act as an earth ................ Imagine putting the inner cable across the battery terminals and that could be happening inside the out cable

    thanks for reply,

    What would happen if they were loose?
    Are they easy to get to?

    Can anything else bind in the carb?

    Ive been using this carb for about 2000 mls without any problems, untill now, this prob showed it self first on firm excelleration on a duel carrageway a few weeks ago and it didnt back off without hard quick pumping of the throttle.

    will check the earth staps for sure....amazing.

    does not have a kick down cable, just uses vacum.

    when you move throttle by hand its seems to move freely with or without engine running.

    Butterflys seem fine cant see or feel any binding, 4 screws seem fine and intact.

    I will look at earth tommorow.
