Below is the procedure for setting specs on G-60 models. As you can see this is not for the DIY and you will most likely have to have a shop do it. So it's for your information and maybe Jan can add it to the FAQ's.

Corrado Basic Engine, Checks / Adjustments

Basic Engine Settings

1. Check and adjust the basic engine settings in the following order:
   1. Ignition timing
   2. Idle speed / CO content
2. Checking and adjusting conditions:
   1. Engine oil temperature must be at least 80 degrees C (176 degrees F) and
      radiatior fan must have operated at least once
   2. All electrical consumers switched OFF (radiator fan must not be running during checking or adjusting).
   3. Idle switch functioning properly
   4. Idle stabilization OK
   5. With ignition OFF, connect VW 1367 engine tester
   6. Install the voltage splitter test adaptor VAG 1473 in between the ignition coil and
      the VAG 1367 using the VAG 1594 adapter kit
   7. Connect SUN 105 CO tester (or EPA approved equivalent) to CO tap using Special Tool 6006-0019 or equivalent (high temperature silicon connecting hose)

(NOTE: Non-approved hose may dramatically alter CO readings.)

Ignition timing

1. Start the engine and let idle
2. Remove the blue connector at the coolant temperature sensor. The second sensor (black connector) is used for the coolant temperature gauge.
3. Check ignition timing at 2000 to 2500 RPM. Checking: 4 degrees to 8 degrees BTDC.
4. If adjustment is necessary, destroy tamper proof cap that covers the head of the distributor base clamp bolt.
5. Loosen distributor and rotate until specification is correct. Adjusting: 6 degrees +/-
   1 degree BTCD.
6. Reconnect blue connector at the coolant temperature sensor.
7. Raise the engine speed three time then let the engine return to idle.
8. Continue to idle speed setting.

(NOTE: It is not necessary to install a new tamper proof cap on the distributor base clamp bolt.)

Idle Speed / CO Content

1. Pull crankcase breather hose off pressure regulating valve and turn it so that only
   fresh air will be drawn in.
2. Let engine run at idle.
3. After approximately one minute disconnect the blue connector at the coolant temperature sender.
4. Raise the engine speed four times to over 3000 RPMs and then let the engine return
   to idle (This cancels the hot start idle increase function).
5. Adjust if necessary.
6. Remove tamper resistant plug over the CO screw, rotate both adjustment screws
   alternately.
   --- the idle speed is 800 +/- 30 RPMs --- and the CO is around 1.2 %
7. Reconnect the blue temperature sensor harness plug.
8. Raise the engine four more times to over 3000 RPMs and then let the engine return to idle.
9. Check to make sure that the CO did not go out of specs. --- If the CO is out of specs, check the oxygen sensor system.
10. With the settings correct shut off the engine and reconnect the crankcase breather
    hose.
11. Install a new tamper resistant plug over the CO adjustment screw.
