95 H22A Problem

Car Sometime 'Spits & Sputters & Misfires" but not all the time, usually before the car is warmed up when it's cold and damp outside, but also acts
up occasionally when nice outside and after the car warms up. New Plugs, plug wires, distributor cap (Converted to external coil), EGR Blocking Plate & Cold Air Intake. The computer is throwing codes for EGR (Obviously) & 20 Electrical Load Detector. Any ideas where to look for this problem or what to try next??? Any help greatly appreciated.
