It's rather hard to believe no code has been set with the electronic Throttle Control dumping into limp mode (limiting rpm range or shutting off injectors completely). Basically this is an elaborate electronic gas pedal run by various sensors and computer and input from your gas pedal. There just has to be a code here, otherwise everyone working on the car is really going to be in the dark. There are so many possibilities to guess at. Perhaps the dealership will just have to resort to parts switching until it clears up if they can't pull a code.

You may have to insist that a factory technician be dispatched to the dealership to help them.

I didn't see any Technical Service Bulletins or Recalls related to this problem, sorry.

I had the same problem with my 06 LIncoln LS (32,000 miles). Eventually, I was able to get a code stored in the computer (after leaving it with the dealer twice as well!). It turned out to be the throttle and they are replacing it as we speak....Hope this helps.

Mr. Shiftright,

I'd like your thoughts, as I read your reply and thought it was most similar to what I am experiencing with my 2004 Lincoln LS V8. About a week ago, the "Check advancetrac" warning came on, along with the ABS light. Yesterday, the "ETC Engine failsafe mode" appeared. The Ford/Lincoln dealer did not give me the codes, but stated that the codes indicated needing a new throttle body. This will run $900 with parts and labor. I've read other threads where they fixed a similar problem with replacing the coils on the spark plugs, or the powerpacks on the plugs. interestingly, this all happened after several heavy recent rainffalls. I noticed others have seen issues after powerwashing the car or after heavy rains. Could my problem just be because of rain leaking? I also had water dripping on my left foot while driving, and water in my left front trunk area as well. Before I drop a grand at the dealer, could it be I need to replace the coils on the plugs before they install a new throttle body? Will this be less or more expensive than replacing the throttle body?

Anyone's help is appreciated. Thanks!
