And the Miata's in the shop once more, same issue as last year's problem. I'm reaching that point where if someone totals my car, then I won't shed a tear for it. It's likely some sort of solenoid involving the throttle or something. At least the dealership has seen this car display an issue similar to this in the past and was able to fix it (now it seems like it was a temporary fix).
R33 goodness to offset the suck.
