Hi, we are back, we put in new injectors, new fuel filter, new distributer cap and rotor, new plugs and plug wires and finally another MAF and the car was running super great, now several eeks later it is running very rough at idle and almost quits with the AC running. When we rev it up it appears to be running smooth, Where do we go from here

When your car engine runs rough while on idle it means that there is a misfiring of one or more cylinders. A lot of reasons why an engine cylinder misfires and is very difficult to test but the most common causes are bad spark plugs/wires, a vacuum leak or burned and out of adjustments of one or more valves.

you might try just turning the idle up a little. There should be a little screw at the end of the throttle cable.
