gas pedal doesn't always work
Yesterday, while driving in town the gas pedal stopped working unless you pushed all the way down. I pulled over and turned off the car and then it worked fine. Turns out my wife said this has happened before, thanks for telling me!! I have no malfunction warnings. Can someone help? Thanks

It may be a defective accelerator pedal. On thing you might try is the electronic throttle re-sync:
1. Make sure everything in the car is turned off and closed.
2. Turn the key to position 2 so all the dash lights are illuminated.
3. Press the accelerator fully to the floor, depressing the "kick-down" button.
4. Hold he pedal for 5 seconds and continue to hold it down.
5. Turn the ignition switch back one click to position 1.
6. Release the accelerator pedal, but leave key position 1.
7. Sit quietly and wait for about two minutes - do NOT open or turn anything on.
8. Listen for a "click" or "ping" noise form the dash.
9. Start the engine and drive the car for at least five minutes.

Thanks Rodney. I'll give that a try today. If it doesn't work, can I replace the pedal myself? I bought this car 2 years ago with 18k miles from an old lady. It's now got 38k and I'm seeing a lot of repairs. new motor mounts, windsheild washer pump, leaking grommet on tranny, bad srs wiring under the seat, window regulator loose, 2 sets of valve cover gaskets Is this normal?

Yes, the pedal assembly is a fairly easy DIY. As for the other issues, those are all fairly common. Use genuine MBZ valve cover gaskets - aftermarkets are too thin.

Sorry it took me so long to respond but your suggestion to reprogram the pedal worked like a charm. The click in the dash took all of 2 minutes and was very very faint. Thanks for your help.
