I need to know the original setting for the idle screw and how to reset the ecu. The car runs a little rough like its miss firing. It has a lot of bog in first and at 3000 rpm. Can you help me out.

To reset the ECM, remove 7.5 A BACKUP fuse in under hood fuse box, or remove the negative battery cable, for 10 seconds. The misfiring problem may be from a number of things; e.g. old spark plugs, rotor, distributor cap, and wires. You may even want to remove the ICM and coil and have AutoZone test them for free.

Here's how to adjust the idle rpm:
