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!
