1985 regal, v6 car with factory cruise. It works, kinda. Sometimes it pulses. It seems to directly coincide with the bouncing of the speedo needle. I can slap the dash make the needle jump and the cruise will momentarily drop out. It acts fine sometimes but usually after a while will end up pulsing like your pushing the gas and letting off quickly. The cruise light never goes off so the system is active the whole time, I'm sure I have the vacuum lines hooked up correctly, it wouldn't work at all otherwise, but I know it takes it's reading from the speedo cable... Will a bouncing needle/bad cable cause this?
I'm cornfused.
