Ikchris, I think you have it. My symptoms fit slightly-leaky injectors perfectly.
- When cold, the leaky injectors have had time to deplete pressure, and also some fuel evaporates from the cylinders over that long period. And you need extra fuel anyway, so it fires right up like normal.
- on a short stop when warm, they don't have timne to leak down, so it's not noticeable.
- But when they sit a couple hours or more, that's the killer.

Makes sense.

Any way to do an easy leakdown check of the system, to at least see if we're on the right track? Course it could be leaking back from the fuel distributor also. On GM car's a leakdown is simple, don't know so much about these CIS systems.

Hmm, wonder if you vould let it sit the proper time, nick the engine over without starting it, and pull plugs to look for wet electrodes?
