While attempting to install new headlights, I removed the negative on the battery. After putting the negative back on to the battery, the system has reset and has not rebooted since then. The car is in minimal driving condition, performance has significantly dropped and the steering wheel locks while driving at high speeds, the engine knocks and shakes at high speeds, there is no more turbo boost and while flooring the gas pedal, the car is hesitant to increase speed.
During colder starts, the engine will take much longer than it should to start. Either it will try and crank until it does or it will crank and stall. Usually a few tries and it will clear up once the engine is warm. I think this might have to do with the intake valves being warn out prematurely. Many other SAAB owners in the same few years and mileage are having this problem.
Upon start, rough idle and misfires. Occasional stalling. Defect traced to metallurgical issues in the intake valves of the vehicle causing an improper seal when the engine is cold.
2007 SAAB 9-3 the vehicle stalls during hot and cold weather. Sometimes the vehicle runs "rough" the vehicle has then stalled in the middle of an intersection. The vehicle has been to the dealer six times for this problem. SAAB USA has been made aware of this problem and I advised them I want them to buy the vehicle back.
