Clean MAF wires and reduce timing to around 27-28.

Yep check fuel delivery also..
Check PCV or raise it so less oil is sucked up through inlet..
Oil in combustion chambers promotes detonation...
Also creates small carbon deposits in chambers which glow causing detonation...
Raising PCV higher away from inlet is often enough...
Acts like an oil separator...
