[QUOTE="mwolson, post: 13453714, member: 16006"] The PCM reads the VSS signal. If it sees that the car is not moving, it drops the RPMs very fast. If it sees that the car is moving, it does not drop the RPMs as fast. If the PCM is not seeing a VSS signal, it assumes the car is not moving. When it drops the RPMs too fast while the car is moving, the load from the power steering and brakes can kill the engine. So power up your Speedcal and this problem will go away. [/QUOTE]
