I suppose it could be the air temp thingie, but your ecu works when
warm.

Quite possible - or perhaps justa  cleaning of the little screens under
the fuel connections on it.

> *cold start valve needs replacing

probably not.

> *1 or more flaky injectors/seals

replace those seals anyway, but probably not this.

What about the temp sender for the ECU?  I think its a multi function
unit on that car, four pin thing under the upper radiator hose flange?
