Got an odd problem with the cruise control in a '95 850. I've read many posts about 850 cruise control problems, most dealing with a broken vacuum hose under the battery. I found and fixed that issue but my car's problem did not go away.

Here's what it does:

1. When the cruise control is set, the car's speed drops about 4, maybe 5 MPH, then the cruise holds at that speed. Example: if driving at 75 and set the CC, the car coasts until it gets down to about 71, then the cruise maintains speed. I believe it works fine maintaining the slower speed (getting this information second-hand from son who is driving the car to school).

2. When using the "slow down" function (button on end of turn signal pushed down), the car will slow as it should, but when the button is released it drops another 4-5 MPH and holds that speed. Pretty much the same as (1) above, except using the slow down function instead of the initial CC set function. In both cases, the cruise maintains a speed about 5 MPH below where it should.

3. "Resume speed" does not work. Can feel the gas pedal move when resume is "engaged", but within about a second the cruise disengages. Of specific interest, it does _not_ resume and hold a speed 5 MPH below the previous set speed. If resume is engaged repeatedly, each time the gas pedal moves as if trying to reset the cruise, but it quits trying after a second.

Hopes were high when I found the broken vacuum line under the battery tray - I thought I had an easy, cheap fix using a "textbook" brickboard solution. Unfortunately this one didn't go away quite so easily.

Any help appreciated,

Terry
