Engine Pings on Acceleration - Where do I start? 200 1990

Mark,

Here's an easy one for you.

Check your air box thermostat on a warm day.

If it's working, it should be closed on the pipe coming from the exhaust manifold.

If in doubt, just block the tin pipe with something, then make sure only cold air is being let in.

It happened to me that only hot air was being let into the engine, and I was getting pinging on hard acceleration. After blocking the heated air pipe with tin foil, my pinging is completely gone on 89 octane.

Also, I think as long as you are not getting pinging then use the cheapest clean gas available (coming from a gas station that is busy).

Cheers,
