For the last couple of weeks, I *think* my STS has been having very short glitches while driving at a steady speed with the cruise control on. It's not a miss, and it's very short - half a second maybe, a "fluctuation in the force". I could be imagining it. It seems to happen every few minutes, especially if I start up or down an incline. There's no Check Engine light, and it seems to run fine most of the time. The only other thing I've noticed is less mileage - 22-23 mpg at cruise compared to like 28-30 in the 2 loaner DeVilles I've had recently, at similar speeds.
Can anyone think of an explanation? Am I just crazy? I know the dealer would just say "could not duplicate customer's concern".
