2005 v50 mixture adaptation error
 

i keep getting this code coming back saying mixture adaptation error detected.
the car has 95,000 km, and every time i scan it i get a different second code but the adaptation code keeps coming back.
the second codes i have been geting are camshaft timing bank 1 intake mechanical fault, tank leakage detector leak detected, ignition failure recognition misfire detected, and outside temp sensor signal faulty. each time i scanned the car and then reset the codes i got the first code i listed and then one of the other codes. strange eh.

any ideas?
