Hi guys,
Stock internals, headers and exhaust 1993 L05 in my Caprice.
The car has been running like Cr@p, did all the tune up stuff, no Joy.
checked timing, it was correct at 0 W/spark control unplugged.
Then I reconnected, reved the motor and noticed that the spark was being retarded almost to the point that I couldn't see the mark! (timing mark moves almost back to the powers teering pump)
Prior to running poorly, I had to run high octane to keep from pinging.
What gives, Knock sensor?
