false knock??
I'm trying to track down the cause of spark retard-15 degrees at times...
Noticed I'm getting up to 4 degrees of retard in neutral while lightly revving motor with long and short fuel trims right at 128 (Not running lean)Does that mean its a false knock or possibly a bad knock sensor?
