HERE ABOUT A MONTH AGO MY CAR STARTED SMOKING. ITS FINE AT IDLE I GIVE IT GAS AND IT WILL BLOW OUT A BIG PUFF OF BLUE SMOKE IT ALSO SMELLS LIKE ITS BURNT....ONLY TIME IT SMOKES IS WHEN YOU HAVE BEEN SITTING AND TRY TO TAKE OFF. I DIDNT SMOKE AT ALL WHEN I TOOK IT OUT OF THE 02 GT. BUT IM THINKING I MIGHT HAVE GOTTEN IT HOT AND MESSED SOMTHING UP BECAUSE I DIDNT TAPE 2ND SENSOR UPON SWAP AND IT OVER HEATED ON ME IN THE OREILYS PARKING LOT ...ANY SUGGESTIONS GUYS ? ALL HELP IS GREATLY APPRECIATED !

blue smoke means burnt oil. Check your spark plugs and see how they look. Likely is the piston rings depending on mileage.

Valve seals can do this: High manifold vacuum leads to high vacuum in the ports which pulls oil through leaky seals. It gets burned en masse when the throttle is cracked and things start moving.

If you think the motor was hurt by overheating, do a compression test and, if you can, a leakdown test to see if a head gasket's been compromised.

Boost would be the last thing I would think of for any car that's smoking.
