The car: 3800 supercharged Series II with stock Fiero cruise control
I noticed that my cruise control isn't working properly. Determined that the cruise servo isn't strong enough to open the throttle plate on the 3800. When I removed one of the 2 springs on the outside of the throttle plate, it opens easier and cruise works properly now.
I've tried a few different cruise servos and they all behave the same. Anyone else run into this issue? Is there a way to make the servo stronger? Or have other just removed one of the throttle plate springs?
Fiero cruise servo not strong enough

Not sure when the electric cruise was introduced, but if it looks anything like the servo that's on your car now, it's vacuum.
Have you checked your *servo* and vacuum reservoir for vacuum leaks?
Is your throttle body the stock 3800 piece? I can't believe that no one's had this issue before... I would have expected someone to have encountered it. That's why I'm really thinking that there's something wrong with your cruise system...
