EXCESIVE SMOKING ON IDLE ONLY

Not much info - there were lots of 2.2 engines in 2006. Probably valve guides or valve seals are worn. Are there a lot of miles on the engine?

most likely valve stem seals failure or worn valve guides
the high vacuum in the manifold draws the oil down each time the inlet valve is opened

Pull your sparkplugs out and check for plugs soaked with oil.If you find any wet with oil then you have worn valve seals or valve guides my guess would be valve seals.

burning oil, worn piston ring, bad valve seals. if its smoking bad it should have a check engine light on. check codes that will tell you the problem.

More than likely you have worn engine valve guides and or seals.

CHECK YOUR PCV VALVE FIRST IT MITE BE STUCK IF OK THEN YOU HAVE BAD VALVE SEALS OR VALVE GUIDES OR BAD PISTON OIL RINGS BUT TRY PCV VALVE FIRST HOPE THIS HELPS

SMOKING BLUE YOU HAVE LOW COMPRESSION ENGINE BURNING OIL.YOU HAVE WORN VALVE GUIDES ALSO VALVE SEALS AND WORN PISTON RINGS.

most likely worn valve guides and probably dry cracked and fallen off valve stem seals you may get lucky with just replacing valve stem seals but may need guides installed in heads

color of smoke

Smoking on overrun is generally (almost always) worn valve guides. But a car with worn valve guides @ low mileage is odd. You might try a little heavier weight oil and maybe a switch to mineral oil rather than synthetic just to see if you can change the behavior. Don't worry about mixing the types, that's OK.

There is a test for worn valve guides. Hooking up a vacuum gauge to an unmetered vacuum source (after the throttle body), the gauge will show an oscillation of about 4 inches of vacuum (at idle). 15 inches is considered normal so from an oscillation 12 to 17 would indicate worn guides.

Good luck on your mission.
