Hi People please help.
I have an 2001 b4 liberty stock car no mods, It keeps throwing the cam sensor code when i turn the a/c on and runs rough. Also on start up idles rough for a couple of seconds then runs fine , we have replace cam and crank sensors and its still doing it.
Any ideas
Thanks Dave

Don't use the aircon?
But seriously are there any stored codes? or was there any stored codes?
You should check for leaks around intake at the throttle body. As well check your MAF/AFM not sure which one the B4 has. As well check the IACV.
Has the O2 sensor ever been changed?

Check the ground points on the engine. The electrical load of the air con clutch could be playing funnies with the ground wire of the cam sensing

And also check the main engine harness doesn't have any water/moisture in them
