like the title says, it rolls up and down 6 miles per hour. No matter what speed I set the cruise for, it rises 4 mph, then drops six, rises six, falls six. Do I have a bad cruise servo, or what's up?
Thx for any help-Jason

 

Please help!

 

Any recent work done to the car? Can you check the vac line to the tank and the tank itselft for any leaks.

 

Front axles were just replaced, but no engine work...
I'm an idiot... What tank are you referring to?
Thx.Jason

 

The tank is by the actuator....left/drivers side fender.
