Thanks for the response.

1. Coolant temp sensor checks out good. Ran the engine long enough to get it partially warm ( worried about the catalytic converter) resistance was 700 ohms. Seems to be about right for the estimated engine temp of around 100deg. Started engine with sensor disconnected. Ran richer/worse.

2. AMM - ??????? Got a response from Art B. with a test I haven't tried. AMM is a remanned unit about a year old.

3. Checked vacuum line. Nop gas. Idle changes momenarily when vacuum unhooked. Tapped in pressure gauge and fuel pressure is in the correct range.

Thanks for trying. let me know if you have any more ideas.
