2. Connect ignition coil No. 1 and spark plug No. 1 with suitable
high-tension wire as shown, and attach timing light clamp to this
wire.
3. Check ignition timing.
Idle Mixture Ratio AdjustmentABS00E4E
PREPARATION
1. Make sure that the following parts are in good order.
–Battery
–Ignition system
–Engine oil and coolant levels
–Fuses
–ECM harness connector
–Va c u u m h o s e s
–Air intake system
(Oil filler cap, oil level gauge, etc.)
