It's not an 'acceleration' controller it's an Idle air controller (
iac).
If you have an autronic then the factory reset wouldn't apply anyway.
I must of missed the bit where you mentioned the Autronic?....Ah you didn't! details would be nicde if you want people to help you.
But for a stock
ecu using the check memory & clear memory connectors under the dash to help the
ecu forget bad habits is the best method to stabilise the idle.
