Having problems with your 1990 Jeep Cherokee Limited ?
Stalls when engne warms up
\015 Runs and idles fine on cold start. will run well for about five minutes, then begins to sputter then stalls. Hard to restart, or sometimes will not start untill it cools down.\015
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.
