Ignition timing should be checked and adjusted whenever spark plugs are replaced or any distributor maintenance is performed. Ignition timing at 1000 RPM or less should be as follows: on 1989 1.3L/4-79 engines, 3-7°BTDC; on 1990-92 1.3L/4-79 engines, 0-2°; on 1.6L/4-97 engines, 1-5°.

the best way to test the egr is unplug the vac hose and put a vac pump and gauge on it and see if the egr moves in and out.
then u can check it for binding or sticking.
sometimes a chunk of carbon gets loose and gets stuck in the valve itself and therefor will need to be removed and the carbon cleaned out.
