Bucking on acceleration.

 

My 03 Chrysler Concorde would buck on acceleration, this in turn gave different false codes. Codes such as P0340 camposition sensor, P0344 Crank position sensor, also codes like P0032 where being detected. After replacing all said sensors and still having the same problem, I came across a post from a mechanic that said dont you find it strange that all your sensors failed about the same time. I was then directed to check and make sure the timing did not jump from all the bucking, it had the timing belt jumped 2 teeth. I reset the timing, went for a test drive and the car bucked again, which again made the timing jump. the only logical set to take after all this was the look in to fuel delivery. I the Concorde the fuel pump aslo has the filter, and pressure regulator built in. After this was replaced the car drove like new again.
