Timing Issue? I wish I could get this thing to stop pinging!
OK, fixed several problems only to uncover more, now after new plugs and an adjustable vac can my truck PINGS under various conditions.
I have my initial timing down to 10 degrees and have eliminated all but a few situations, namely hard accelerating out of a turn. Partial and WOT throttle under load (going up hill) no longer ping but if you goose hard it coming out of a turn it will ping, but if you accelerate moderately and build to full throttle it is OK...
I really wish I could get it back to how it behaved with the *wrong* plugs in regards to not pinging...
I was thinking about lighter mech adv weights in my dizzy and playing with spring combos and adding vac adv to tune my curve, as it is I am all in around 2000 RPM - and right now my total mechanical advance is 15 degrees
