Hi

when outside air is warm and the engine as well, it stalls when I brake hard or nearly stalls. It sometimes combines with the oil pressure light coming on...

is that bad? it is not good that is for sure...

cheers

 

anyone ? (ferris bueler teacher mode)

 

Do you have access to a hammer or scantool? I would look for error codes. I would also ask how old your DME relay is? Perhaps it should be replaced.

 

I have a RS America with a light weight flywheel that suffered this problem. What I have learned is that if power is cut off from the battery, the DME loses it's idle programming. Once the car is re-powered and started, the DME will re-learn the proper idle, but the engine needs to be warm when it re-learns the idle or you will have problems once the car does warm up. My tech told me the re-learning takes place in the first 20 minutes or so. Another solution is to use a Bosch hammer to place the DME in learn mode after the car is warmed up. It is a very frustrating problem.
