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. |

Nope I can't get to the engine for all of the sh*t I have piled up. Maybe somebody else will know what I am talking about.

It's right there under the #1 runner where the 3 hoses seem to intersect. All I remember is there is also a small steel body with 2 ports down there also that the "Y" connects in with. See the green hoses from the intake boot and the air filter? That is the metal part and the rubber piece is there as well.
