I have been having a problem with my car when it is stopped at a red light while running. When I am stopped, the car will idle roughly and will jerk back and forth. I have replaced the camshaft position sensor because I thought this was the problem at first. I just put the new camshaft position sensor in and now when I am in park and put car in reverse, the car idles and turns off. Did this twice. Could this be due to a bad/failing crankshaft positioning sensor? Or something else?

What other things have you checked? Have you changed the air filter and fuel filter? They can cause rough/erratic idle if they get clogged. What made you think it could be the cam position sensor? Any codes?

Two weeks ago I got an oil change and they changed the filters. Yes, I am received couple engine codes: P0011, P0013, P0014, P0016.

Being that all of those codes are cam and crank sensor related, I think that you probably need the timing chain itself replaced. From my research, this combination of codes generally points to the chain being worn out.
