1997 Acura CL that when warmed up then restarts when cool

SOURCE: Stalls when engne warms up

Your ECT (Engine Coolant Temp) sensor is bad. What's happening is at cold start it richens up the fuel mixture and as it warms up the ECM thinks it's still cold and essentially the "choke" is still on. Also check your coolant level. If you don't have enough coolant in you engine/radiator, the ECT doesn't know what to do so it thinks it's cold.

Most likely air flow metre. Had same problem analysed and replaced and runs perfectly. Not cheap!
