Grounded the timing terminal, and grounded pin 10 of the self-diagnosis connector.


Only ground the one under the hood.


I would back the screw out half way and run it while (off- on proceedure)to let the computer get used to that... then try adjusting the screw.

Also make sure all grounds are good.
