Recently my Concorde has gotten into the habit of stalling 10 minutes into driving. This is usually followed by 5 minutes of failed atempts to restart and has even stalled soon after getting it started again. Once it has started again, there is usually that rotten egg smell and check engine light. It will also shake/stutter while diving down the road, almost feels like I am driving a manual transmission and have trouble shifting gears around 40 mph. One of the trouble codes is P0440 and the second was for a cam sensor (not sure of exact code). I have replaced the gas cap as many mechanics have recommended but this code keeps coming up. Any suggestions or ideas as to what is causing it to stall?
