My '05 chevy cavalier keeps intermittently losing hold of the cruise speed I have set. I can go for 10 miles, then suddenly it will let the gas pedal up; I can re-set it, then 2 miles later it lets up again. What could be the problem - sensor? vacuum line? ---

One thing to check is the brake light switch on the brake pedal. If that is set to close, just a road bump may give an intermittent ‘on’ which will put the cruise control in standby. Hope that is what it is. ---

I also suspect the brake light switdh ---

Thank you so much. I forgot to mention that it seemed to cut off after going over bumps - I guess I didn’t think that could be an issue, I will definitely check the brake light switch, sounds like this could be the problem. You guys are great! Thanks again. ---

Besides the brake switch, check the brake lights, especially the center mounted one. I was having intermittent issues with the cruise on my 93 Caprice before it stopped working entirely. The center brake light had burned out disabling the cruise control. Ed B.
