Cruise Control Gremlin

[rj7630]

The cruise control on my 91B automatic works reasonably well. But when I am in the 60-65 mph area and set the speed, it likes to accelerate another 5 - 8 mph. So if I want to cruise at 65, I need to first slow to about 60 and set the speed. It then adds another 5-8 to that. If I am going 55 - 60 or 65-70 then it only speeds up a couple of mph. It's just that 60 - 65 that gives it big problems.
My previous 91 had this same issue. Is this just part of the 164 experience or is there something to check out?

Do you just tap the set button? On mine if I set it with a tap it stays where I want it. If I push and hold it too long it will accelerate as you say.

Might be the first sign of a speedometer sending unit going bad. I had one do that several years ago. It got so I couldn't use the cruise control at all, then the speedometer stopped working. When I replaced the sending unit everything started orking again.

I tend to push the set button vs a tap. I'll give that a try and see what happens. The sending unit might be an issue as well. I noticed a copuple of weeks ago while cruising down the freeway that the speedmoeter was dropping down into the 40mph range. It quickly recovered and I haven't noticed any problems since, but cetainly something wasn't quite right.
