Re: 3.1 Engine hesitates after restart when hot

That's a good piece of advice, but it would be more effective to connect a fuel pressure gauge to monitor actual pressure. I've had TBIs do the same thing, and almost always fuel pressure was a problem. That vintage will probably require an adapter to be connected at the inline fuel filter in order to read fuel pressure, since there is often no test port provided from the factory.
