Replying to: sgoss (Jan 16, 2008 9:43 am) I pushed the clutch in and applied the brake in the usual gentle manner. Once I had come to a stop I noticed a couple new lights on the dash. I then realized the car had stalled. I started the car again, accelerated forward a little then hit the breaks, same thing, it stalled again! I then thought it might be due to excessive power draw (please note lights were not on, nor was defroster... just radio, AC to dehumidify, and wife's seat warmer). At this point I turned seat warmer off, likely largest draw. I then accelerated and hit the brakes, the rpm slowly came down as normal then dropped below the 300 rpm line and lugged but recovered (barely). Anyway, after that day I have now always nervously watched the Tachometer when clutch goes in or I stop. I have noticed the RPM going very low and lugging many a time but no stall. Now it has only been a few days since the stalling and I believe I know what the problem is! When you start the car the blue/cold engine light is on. If you drive away without allowing the car sufficient time to warm up (and the blue light go off) then the idle seems to run lower and recover from an RPM drop poorly. I believe this may be the computer learning the precise idle mixture requirements for idle (given atmospheric conditions). If you drive away too early it is not given adequate time to make the adjustments. Please let me know as I have ensure blue light goes out always since then and all lugging has even gone away completely.
