Hi Robert,

My 91 Carat cruise must be held in to accelerate.  It will not take a
"pulse" to bump the speed up by a 1 mph increment, like our 91 Park Ave
cruise.  As for the engage, I'd guess you may have a dirty contact in
the switch or column. I've never looked for this on my.  I did have a
aftermaket Dana cruise, and had to open the switch up a couple of times
in the 15 years I had the car, to clean the switch contacts, and then it
would engage instantly again
