Hehehe! Palit mekaniko na nga muna ako eh. Mejo bisi lang last week kaya di naasilkaso. Bukas, papuntahin ko na bagong mekaniko.

Just found the specs for the 4AFE ignition coil.

Ignition Coil
5. INSPECT PRIMARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between
positive (+) and negative (–) terminals.
Primary coil resistance (Cold):
1.1 ~ 1.7 at –10 ~ +40°C (14 ~ 104°F)
If the resistance is not as specified, replace the ignition
coil.
6. INSPECT SECONDARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between the
positive (+) and high–tension terminals.
Secondary coil resistance (Cold):
9 ~ 15 k at –10 ~ +40°C (14 ~ 104°F)
If the resistance is not as specified, replace the ignition coil.

Check ko yung sakin. Baka nga ignition coil.

Thanks!

Sometimes it passes the resistance check but fails miserably on spark test. The coil should be able to snap a bluish white spark from 3 inches to ground when tested. If the spark happens around the coil, the insulation had been breached
