Tune-Up Notes

NOTE: In order to comply with emission standards, specifications shown on engine compartment emission control tune-up decal must be used in all instances.

NOTE: The 1.6L engine is supplied with 2 different emission control systems. "System A" applies to all Federal models (except 5-speed). "System 8" applies to all other models.

CAUTION: Before making compression test, or cranking engine with a remote starter switch, disconnect ignition switch connector (pink wire) from H.E.I, system.

CAUTION: Do not remove spark plug wires with engine running. H.E.I, secondary voltage is higher than standard ignition systems and may inflict harmful electrical shock.

CAUTION: Damage to the H.E.I, electronic module and/or coil may result if "TACH" terminal is directly grounded.

ENGINE COMPRESSION

Compression Ratio
	1.6L	9.2:1
	1.8L	9.0:1
	2.0L	9.0:1
	2.5L	8.2:1
Compression Pressure
	1.6L	145 psi
	1.8L & 2.0L	100 psi (Minimum)
	2.5L	140 psi
Max. Variation Between Cylinders
	1.6L, 2.5L	20 psi
	All Others	30%

Test compression pressure with engine at normal operating temperature, all spark plugs removed and throttle and choke valves wide open. Crank engine through 6 compression strokes to make compression reading.
