Spark knock on throttle snap
A friend of mine just got his 94' camaro back together. He has done a comp-cam and that's about it. The car idles rough and will stall after some time. The main concern is related to timing though. When you snap the throttle at idle it has pinging bad and will pull out timing. What can cause this or have any ideas on diagnosing it. Replaced Opti-spark, checked cam timing just to be sure. Any suggestions would be greatly appreciated. Thanks
