I own a 1994 430E and had trouble with deceleration. The car is drivable for about a mile before it seems to lose ability to hold speed, it then decelerates completely.

The diagnostic said Electronic Throttle Body Actuator and Cruise Control Module. Numbers are 1245453632 and 0001419425 - I believe they're part numbers.

We can't afford to have both parts replaced.
- Does the car need the cruise control module even though we don't use the cruise control?
- Anyone know which part it could be by the description of the problem?
- Would it operate fine without the Cruise Control Module if only the Electronic Throttle Body Actuator was replaced?
-Is there any way to discern which part needs replacing? Thanks!
