My 2002 Jeep Liberty is running extremely rich and both short term fuel trims are showing 99.2 with no codes
2002 JEEP LIBERTY
It barely idles and is burning fuel worse a gas hog v8. I've scanned it with absolutely no luck. Any help would be greatly appreciated thanks
have the same problem?

Probable causes of an engine running rich are as follows:
1. Excessive fuel pressure can be cause by restricted fuel return line
2. Defective Oxygen Sensors.
3. Leaking injectors and fuel pressure regulator.
4. Coolant temperature sensor out of calibration.
5. Restricted air intake system

I found out Monday that it's only running on two cylinders. Fuel pressure is 55 pounds at idle. Map kpa is around 80
