Alan,
Thank you for the suggestions - will keep them in mind as I move forward.
The car doesn't come close to failing - it just occasionally runs wierdly under
certain specific circumstances.
BTW - today I filled it with Arco Premium (vs Unocal regular), which tested at
5% alcohol.
Will report back to the list if it runs better with the Premium gas.
