The engine shuts off when using the left turn signal, when trying to restart all dash board lights flash and the fuel gauge sways from left to right, the drive lever locks in the locked position and the car will not start. After letting it set the dash lights continue to flash and won't start. If you turn the hazards on or set the parking brake the car will start but shuts down when driving.
When we first bought the car the check engine light came on and car would not start. Dealer finally found the problem. It was a sensor. Dealer replaced sensor. In March 2003 check engine light started coming on again. It stays on all the time. Some of the others come on to. Service engine soon ect. It has been less than a year since we had it fixed the first time. I think maybe it could be a defect.
