Re: Strange detonation problem
1. User higher octane gas.
2. Check your distributor parts for wear.
3. Check the timing gears/chain for wear.
4. Recheck the vacuum advance for wear.
5. Is the EGR connected?
6. Has the carbon in the cylinders been cleaned out?
7. Is the gas mixture running lean?
8. Do you downshift when it pings?
9. Pinging ain't good in this condition.. it's not a simple timing issue.
