200 Jeep Cherokee Running rough and Multiple codes HELP
Ok... Long story Hope you can Help...
2000 Jeep Cherokee Sport 4.0 A/T
Recently my jeep randomly started to run rough... No engine codes or anything. It was also having issues starting but found that to be the fuel pump (replaced). narrowed it down ans noticed it would run fine when cold but as soon as it hits operating temp it starts to run rough and sometimes stall (no power). I did get one code once and it was P1391 . Replaced Cam sensor, Crank sensor and code did not return but problem is still there. One more thing noticed was there is s ticking coming from the back passenger side when temp is reached (not sure it has anything to do with it). Today I started it after it sat for a week and it really was running rough then smoothed out and when temp reached everything went south. wouldn't Idle and stalled engine light came on and the following codes came up, P0352, P0353, P0135, P0155, P01391... I have replaced the cam sensor with three new sensors and no fix? Any suggestions?
Thanks in advance

Get new spark plugs. If the first two codes dont go away you need a new coil pack. If you dont want the coil on plug you can use the dodge viper coil and use wires. Its much cheaper. When mine fails ill be doing that.
The next two codes are for o2 sensors. Bank 1 sensor 1 and Bank 2 Sensor 1. Those are the top two sensors. I would change all four. The NTK factory ones are about 30 each on rockauto.
Maybe the crank/cam sensor is faulty. I would change all that other stuff first and reset then deal with this.
That ticking noise is coming from this thing.

Actually the symptoms don't seem like faulty cam and/or crankshaft position sensors. They are more like marginal O2 sensors, particularly the two upstream units. Change those and report back. Just out of curiosity, are you losing any coolant from the reservoir bottle?
