So my buddy has had some issues recently with his 08 coupe, for a few weeks its been idling rough and throwing a p0335 code. At first he was able to jostle the wires on the positive battery terminal and it went away but today it won't stay running more than a few seconds and is showing P0335, p2101, p0113, p0223, p0123, p2135. Any ideas.

 

Plot twist. Changed out crank position sensor and that fixed it. Glad thats all it was.
