My new car has been in and out of the shop for the past month (4 times). The check engine light keeps coming on and the dealer does not know how to fix it. The car does not also seem to be able to hold an idle speed. When my foot has the clutch completely depressed and my other foot on the brake, the engine idle just goes from 500 to 1000 and back down to 500 and the car shudders and almost stalls. There seems to be other Scion owners of this new car that are having the exact same issue (there are internet post on web forums dating back to June 2012) and Toyota/Scion does not act like they are aware of this issue at all. I am concerned that the car is going to stall or the engine surge when I am driving it. The car is at a Scion dealer for the 4 time and I was given no eta on when the car might be repaired.
