Hey all,
Have an issue with the cruise control. When I turn it on and hit set, the accelerator jams on full as if the car is loosing speed. There isn't a lot of info on how to start fault finding the issue so any pointers would be good.
The breaklight switch cancels cruise still and everything seems to be in working order, but to be honest I dont know where to start. Do the VL's have magnets on the drive shaft or would it be an electronic component? I saw somewhere that a spring can fail or a vacuum hose but everything appears to be working and connected.
I have a second Auto computer, but that hasn't made any difference.

its a berlina, march 87, RB30E
if that helps at all.

Thanks
