AIR IN THE GAS TALK

SOURCE: car not running right

check the catalytic converter to see if it has restricted flow, i have had the same problem in the past with a car, it would start and idle great, i could rev the car up but the minute i put it in gear it wanted to die, and my cat was clogged

Have you checked your alternator?

SOURCE: loses power while in drive.

To what degree do you lose power and in what way? Do you loose over-drive or does it loose power and speed (on the streets, highway, or at any speed). From your discription it does sound like either a fuel flow/pressure issue or a clogged cat.
