Will it ever end? Not looking good! Options

My car still idles like pure crap. Very inconsistent - high to low surging, super low, rich... you name it, this car's idle is ALL OVER THE PLACE. It's never the same condition. The car runs like a raped ape and goes good, but the idle sux complete ass. I used to be able to get some idle adjustment at the TB screw (I don't have the ECM screw), but today I set the fuel pressure correctly (was at 42 PSI) and now I have no control over the idle mix/speed. Maybe someone in the past tried to cover the problem by cranking up the fuel pressure. I'm not seeing the super rich condition now, but like I said... no control.

I've been through everything: replaced/fixed wiring, new ignition system, battery, cables, checked all the standard fare + what I've listed below, etc. This is getting ridiculous.


What I've replaced thus far:

1. Ignition: Coil, Cap, Rotor, Points, Condenser, Plugs, Wires (all Bosch except plugs).
2. Fuel/D-Jet: TS1, Fuel Filter, Vacuum Lines.

What I've checked, adjusted to spec, or tested to be good:

1. Ignition: Points, Timing, Trigger Points.
2. Fuel/D-Jet: MPS, TS2, Fuel Pressure Reg, Cold Start Valve, Aux Air Reg, Injectors, Fuel Lines, Fuel Pump, Throttle Body, Throttle Switch.
3. Engine: Timing, Compression, Valves.

You may also have a bad electrical connection to the ECU. Wires get old and crack. Dirt also plays havoc on connections. Make sure the connector on the ECU hac clean connections. Also make sure that there is a connection from the CHT (near cyl #3) to the ECU. This connection could be broken.

Don't give up! There is an answer and you will find it.

I'm ready to give up on this D-Jet system - pretty much at the point where I'm ready to switch to carbs.

I've done most every thing that has been suggested here at 914 World + studied Banders site constantly.

The car runs so rich - it's fuching ridiculous. I've got a guage hooked up and I never exceed 30 PSI - so I know it's not a kinked fuel line or the such. I've got brand new ground straps that are super clean + all the injector grouns are good & clean. I bypassed the Cold Start Valve (fuel line wise), checked the TS2 and replaced TS1. My running voltage at the BATT is 13.6 volts. Correct injectors, MPS tested and works fine. The ignition is ALL new and valves have been recently set.

The only thing that I can think that I haven't checked are the trigger points. Could they make the car run retardedly rich? The plumes of smoke will straight up gag you!
