    Gas Pedal Problem

    We have a 2004 Ford Focus LTD, auto tran. with 140,000 miles.

    The problem is with the accelerator. If we hit the brake, or even decelarate suddenly, the gas pedel goes unresponsive, just dead.

    If we stop the car, turn it off and restart we are back in business.

    I dont think it is a the linkage sticking. Is there a module that operates here? Any insightes appreciated.

    dead as in?
    not asking, why you have to have both gas and brake pedal pressed same time.
    you may have what they call drive by wire system. your pedal then has no mechanical link to throttle. throttle is controlled by ECM, based on its own will and gas pedal position from your foot. if you do (dealer will tell you) it's one of electronics gremlins in that system doing this.

    Hi: For those who may be interested, the suggestion was made that the throttle body may need cleaning.

    If you can't accelerate after a sudden brake event...I doubt it just needs a cleaning. That should be easy to do yourself anyway just to check. Throttle body cleaner from a parts store will at least clean the butterfly area.

    I think ukrbyk is probably right...you most likely have a drive by wire. I think a trip to the dealer for a scan and any possible recalls may be in order. This is probably more than a parts store scan could find.

    1.8L Focus C-Max and Focus Mk II versions use a drive-by-wire throttle to improve......

    dirty throttle body and sticky pintle valve show as sticky, stumbling gas pedal after overnight parking, on cold engine. very well familiar.

    Do you have a light on the dash that looks like a wrench? It means there is a problem with the gas peddle assim. easy to replace yourself. I had to do it on 2004. Exployer.

    From what I've heard of this system, there is actually 2 separate calculations made of the gas pedal position and if they vary by more than a set value, the system defaults to an inop status(orange wrench). Switching off ignition then restarting car resets it. I've had it happen 3x in 58k miles with my 2005 F150. I've logged complaints with the NTSB as a safety issue. What happens if you have this failure in rush hour traffic say on 285 loop around Atlanta with 18 wheelers bearing down on you? Needs to be a recall of these early drive by wire systems IMHO.

    GAstorms1, yeah, ANY problem on the "racetrack" would be devastating I had a problem with a 1993 F150 dual tanks. Transfer valve would not operate properly and kept pumping fuel from the back tank to the front tank. Front tank would eventually puke fuel out. NTSB issued a recall. My truck was not in the "list" on the recall. Tried as I could, I never got Ford to fix the problem. I even went to a dealer intentionally with the front tank puking fuel. "not on the list". Had to half fill front tank and fill back tank. So NTSB is as worthless as warts on a frog.
