Vehicle idle would rise and drop, sometimes would stall out. Very rough idle; worse with A/C running. Dealer cleaned throttle-body and intake manifold AND charged approx. $100 to install "driveability upgrade" to engine control software. The throttle-body fuel injection system is obviously sub-standard if it needed all this cleaning, and the software patch, (disguised as an upgrade), should have been free.
