    One of these days, I was thinking of 3D printing the door pulls because I think I can design the inside structure to reduce the weight. You could print in black resin and not have to cover it.
  2. [Fuel] If the dwell reads 0 then the ECU is bad or your...

    If the dwell reads 0 then the ECU is bad or your meter is not reading correct. The minimum dwell the Lambda can set if about 10 deg. Now since you get a buzz pressing the WOT that says your lambda...
  3. [Electrical] What is your voltage with no loads at idle and...

    What is your voltage with no loads at idle and above 2000 RPM? You can read that voltage from the lighter socket. Since no loads all 12 volt and ground connections should be about the same.
  4. [Electrical] As long as your problem is consistent, you can...

    As long as your problem is consistent, you can use a voltmeter with a longer test lead to find voltage drops. First would be to confirm the alternator is producing voltage (about 14.5 volts). So...

    Brake bleeders are the same. They pull air through the threads so you never get the "no bubbles".

    You set it so you don't get ice build up on the evaporator. So if your AC keeps cold and you are seeing condensation dripping then your probably good as is. If you seem to loose cooling and after...

    I was hoping that test of the deceleration valves would solve the problem. Anyway it reinforces that problem shows up when you see bad springs. I can loan you one of my idle ECUs if you pay for...

    Yes the ECU will think the engine is hot with that jumper. If it does not close than I would suspect the idle motor is damaged on the valve.

    The jumper lets the idle motor close to almost fully closed (about 0.1" still open). I don't know why the stock idle ECUs don't close it fully. Just watch is for about 30 seconds with the key...

    If the thermistor was not connected it would only close the the idle motor (just key on no start) about to 3/4 open. If the thermistor is below 5 Kohms then the idle motor will close almost all the...

    That is typical for the stock idle motor. The Volvo one is about twice that.

    Try shorting the thermistor wires and see if it closes. Thermistor has to be plugged into the ECU.

    Don't use a screwdriver to turn the idle motor valve. It's a soft metal and you could damage...

    Try increasing the curb idle screw adjustment. I set mine with a hot engine, turn it clockwise until the RPMs go above the 775 idle RPM then back it off about an 1/8 to 1/4 turn.

    When it goes...

    My guess would be something in the idle system is not working. Does your idle motor buzz? I would guess if it's now holding 775 RPM then it is intermittent.

    An old common problem with a random...

    The advance unit mounts on the ignition distributor and can rotate the internals to change the ignition timing.

    The solenoid is a "switch" for steering the vacuum to advance ignition timing or...

    There is no return spring in the idle motor so pulling the connector should not make it change. Maybe you have a marginal connection on the connector. Next test would be to move the wires...

    Just do a short circuit. The short circuit will do the same as a 5 Kohm resistor.

    Now it does adjust the start opening when starting the engine with the stock or my ECU so if you find hard...
  20. [Engine] Running the thermistor open will only let the...

    Running the thermistor open will only let the idle motor close very little. Quite a bit from fully closed. It's not a controlled RPM so it dependents on the other engine adjustments. Mine ran about...
  21. [Engine] There is a two pin connector on the engine...

    There is a two pin connector on the engine harness that has the orange wire in it. Also has a green wire in the other pin.

    You could also connect to the red/brown wire on the three pin bulkhead...

    With engine swaps and a lot of EFI the throttle bodies should become more available and priced less. In the past you could find them for less $100. If you can find a way to lock yours down to test,...

    That's what my car did for so many years and it turned out to be bad deceleration springs. So far if you look at the springs and see uneven coils you know it's bad but I wonder if good looking...

    I have been helping another owner with his idle problem and he got about the same resistance as you on the idle thermistor. But mine at 75 deg. F (cold) is 20.7 Kohm and 1.12 Kohm when my fans...

    I've always use the smaller size. Thick it's 75 in my D. Only thing with battery size would be how long it would run if the alternator died unless you have sub zero temps.
