Had a flat battery due to leaving the ignition on, then got a low rough Idle. Recently sometimes if you stopped quickly the engine would cut out. Been twice to dealer for rough idle. Ist time replaced front engine mount. 2nd time they replaced all engine mounts. Fault still present. Sent to a local mechanic who replaced the alternator and performed a throttle body clean after that did not work - drove away $695 less money with the same problem. The next mechanic said to replace automatic transmission $2500 approx. Their neighbour said to see me before going any further.

Started the vehicle, very rough idle - shaking vehicle. Scan tool showed 573 to 854 idle rpm.
