Replying to: aj86 (Jan 28, 2008 9:01 am) My 2004 300M Special shutdown on me when I was playing with it on a long trip. On a wide open desert highway in far West Texas I had an opportunity to see how fast the car would go. No traffic, just me and Special. It appeared to be chip limited at 127 mph. I coasted down to about 80 mph (the posted limit) when all the idiot lights came on and the engine simply shutdown. I quickly shifted it into neutral and started braking to get it slowed down to where I could handle it without power steering and get it on the shoulder. It would not restart at first. Then, after pulling the keys, checking under the hood, and trying again it did. It would not run over 2500 rpm! I still had another 200 miles to get home to El Paso. I turned it off and let it sit for about 15 minutes. When I restarted it, all the lights cleared and it ran fine. I made it all the way home, and put it in the shop the following day. I was told the crank sensor failed and it was replaced for $175.00. The reson it wouldn't run over 2500 rpm was it went into a "limp mode" until I shut it off and reset it. The technology is designed to protect the engine, but I wanted to know why the crank sensor would fail. Perhaps the computer got confused by the maximum speed...
