1986 240dl cruise control sticking wide open even in park

I have a 98 86 volvo 240 dl in extremely good condition.
I turned the car on and the motor revved up past the red line. I found if the cruise control was off it would not rev up at all.
I took it to my mechanic with original volvo manual and he could not figure it out
I replace idle control valve, called my self checking hoses and proper vacuum sources but cant figure it out.
I think when shop replaced my accelerator cable and ac compressor etc they hooked up a vacuum or some wire wrong.
I am very desperate as I cant find any help on this issue.
also when I drive it and turn the cruise on it accelerates fast. If I step on brake or turn off cruise the car drives fine.
PLEASE HELP if you have an ideas of vacuum hose routing check, improper wiring or defective part ideas. THANK YOU

Sounds like something is hanging up. Accelerator cable? Check that it is moving freely through the firewall and the cable wheel etc.

This is the AWD/FWD forum. Your best bet for an informed answer is to post this in the RWD forum where all the 240 experts reside...:)
