so, still experiencing chronic but unpredictable drop offs. happens locally and at highway speeds. it coincidentally occurred after that initial cruise test. just yesterday, i was on the highway and decided to test cruise. could not get it to engage. i tried repeatedly, but did not function. light showed up on the dash.
is this throttle pedal unit down near the gas pedal. need to look up location and any service that can be done to it.
