My neighbor just stopped by with this car. Has 177k on it, looks great, but.. runs fine when cold. After just a few minutes to warm up it starts to miss - really rough at idle - shakes the engine pretty good. Continues to miss under light acceleration - clears right up and runs great under hard acceleration. Feels like a gasser with a bad plug wire or something similar.

The "story" was that PO drove the car into about a foot of standing water 6 months ago...car kept running but has had this miss ever since. Sounds to me just like a dirty injector or even air in the fuel system. The dealer - I love this - proposed replacing the entire engine...!

I don't hear any unusual mechanical noises although I'm told the "diesel clacking" is a louder than it used to be. Hard for me to judge because my old 300D and SD have never been quiet!

Anyone more familiar with these newer cars have any suggestions. Any and all ideas are welcome!

Thanks!

Fred
