Q: Car jerks and stalls 1994 Oldsmobile 98

asked by on August 24, 2016

My car has gone around 160,000 miles. When I drive it for about half an hour, it starts jerking and eventually stalls out. The dashboards shows the check engine light on. It will ocassionally start right away but there would be misfiring of the cylinder number one. Otherwise, I need to wait for a while and try restarting it when the engine is cooled down. I've had the codes read and the error code came up, indicating cam sensor issue. I went to a mechanic who had done may repairs, including cam sensor, air flow sensor, computer and timing chain replacement. Also, the harmonic balancer, ignition control module and gears have been changed too. The wiring is checked out as well. The car has no troubles overheating. What should I do?
