2. Remove the intake hoses coming off the turbos, next to the throttle body. 3. BE VERY CARFULL FOR FOD (foreign object damage). 4. Start the car - The engine will run rough without the Air Flow meter registering air. - The computer will compensate with its best ?guess? on the air entering the system. 5. Blib the throttle several times to keep the engine running. 6. Hold your hand over the one of the hoses off the turbo. 7. Blip the throttle harder to spool the turbo a bit, the pressure should push your hand off. 8. Do this for both sides.
If you notice that the turbos fail to push your hand off then you have a frozen turbo that is not developing any boost.
