Has anyone had these problems? I bought a 2000 Jeep Cherokee Sport with the 4.0 I6 on 11/10/04
Check engine light has been on 12 times cylinder #3 misfire
Check engine light was on 4 times O2 sensors
1) check engine light comes on after idling for 30-60 minutes and sometimes just comes on during normal driving
2) idles rough especially when cold
3) sometimes dies after start up
4) sometimes hard to start
