84 Diesel Suburban Cruise Control Problem
I'm New to These Forums So Please Bear With Me.
I have a 1984 3/4 Ton 4x4 Silverado Suburban with a 6.2L Diesel. The Cruise Control in it works only once in a while and when it does work it can't hold the speed steady. (Ex: if you set it to 65mph, it will drop as low as 57mph then throttle up to almost 75mph and then back down to 57 again, etc).
I checked the Vacuum pump and it seems to be working just fine.
Anyone one know what the problem here might be?
