Yep. I've actually theorized for a while now that the tendency for Metros to go into open loop easily, and run excessively rich when they do, is a major factor in why they tend to burn exhaust valves.

I discovered the open/closed loop discrepancy early on in my experimentation with P&G. Our Metro has 254,000 original miles...and it still has good compression.
