Is my timing off? Or is my pcm going out

Cam code does not mean it is a camshaft sensor code, you can a low compression on one cylinder or even a bad headgasket which will cause a rough idle and it will code a camshaft sensor code.

"A code told you to"... Trouble codes are just a hint as to where to start diagnosis so the CAUSE of the problem can be found..... Does not mean to start replacing parts!.. Most everyone just assumes so!!!!
