I thought I had said what was done(complete tune-up) Plugs,wires,caps ,rotors, and fuel filter, and I replaced the EGR pipe, cleaned the MAF, and put a new air filter in. Also I checked all the fuses in the car and under the hood, pulled the main relays that were important and cleaned them with contact cleaner and firmly pushed them back. Also every connector on the engine was unplugged and cleaned,also the ignitors. I also checked the coil wires to make sure the were tight. I've been working on cars for 30 years (I'm ASE certified , whatever that means) the engine does not miss CASE CLOSED, I can tell when a car misses under load, or has a poor/ruff idle. It runs perfect and always has (the PO used to drive it 600 miles on the weekends to play golf) An engine can't run perfectly with bad plugs,wires, fried caps and rotors ! The ECU repair is $100, it took a half an hour to remove it. We'll see.................... :)
