250 miles and weird engine trouble.

New car, 250 miles and babied all the way. So, I go to pull onto a street and my car starts cutting out like there is no gas. It does it repeatedly while I start to hold up traffic. I finally get the car moving and get on the freeway. About one mile later, I get an engine warning light (engine service light) and the car goes into protection mode dropping max RPM to 4,500. I stumbled along at 50 mph for about 3 miles until I see an exit and pull off. I stopped the car and let it sit. I unscrewed and re-screwed the gas cap, got back in the car, and started it up. No problems since then, but definitely weird.

I talked with the dealer and they will check the car. The gas cap thing has been an issue with my 335 and seems to make everything good with the computer when you unscrew and re-tighten the cap. Anyway, I will let you all know what the dealer says next week.

CRAZY!

At least in my 335 I had enough power to get home. In the M3, you struggle to get off the freeway and onto a side road. It took all the car had to get off the freeway ramp at the light! Pretty embarrassing to be in >$70K car and not able to drive!!

Don't worry about it. It ooks like a software problem. Those issues usually gets fixed automatically after a restart. As for babing the car. Don't. You need to put come stress on the engine gor the piston rings to seal.
