I was helping my dad's friend with a problem with his lo47 pajero on 4g54 engine.
He complaint about lack of power.
I check the ignition and it was a mile off at beyond 10degree after tdc.
I reset the ignition to 7btdc and was surprised that the engine backfires so i retune to 5 btdc and let him have a go.he said no improvement and the engine is idling badly and it still backfire.
So,i set it at 7 after tdc and the engine becomes smoth.
This time i went with him for a test drive.i can feel the power is back.
I was waiting for the engine to knock as its not the correct ignition setting but to my surprise the engine did not knock.
Not even when he rev it high.
I there something i miss?
