1991 GT w/ AOD will die when shift to Park.

Hello everyone,

Having an issue with my 1991 GT Conv w/ AOD. Car starts fine in the am, when cold. After I drive it and get ready to park and shift to P, it dies. It will start right up, then does it again. I give it some gas, then shift to D and its fine. Doesn't die when I'm at a stoplight or in N. Only when I to P.

Any thoughts?

You have to get it running a little better. On mine I turned the screw on my throttle body one turn at the cable. I would check for vacuum leaks.

So, it dies while in gear with foot on brake just before shifting to park, or it dies after putting it in park?

Clean the idle air controller and then perform the idle reset procedure.
