From my Chilton's book:
Spark plug type: BRF-82
Gap: 0.044"
Electronic ignition, so info on setting points is not applicable.
Ignition timing: 6deg before TDC (both manual and auto tranns.)
Idle speed, Manual trans.: 800/500 RPM
Automatic trans: 600/500 RPM
Note--Lower speed is curb idle, with anti-stall solenoid disconnected. Also note that idle speed for automatic transmission cars is with the transmission in Drive (and rear wheels VERY WELL BLOCKED). If you have an automatic transmission car, the lower idle speed (solenoid off), is set with transmission in Neutral.
Good luck,
Joe
