2001 4.0L Auto,
So the other day I thought I felt a slight stumble and the CEL comes on but Jeep continues to run fine. Throws P1391 code. I check wires and plugs on cps, cks and computer all appear fine. I unplug computer to reset cel. Today it stumbles again and it feels like its running on three cylinders cel comes on again, while driving I turn off ignition and turn back on and we are back to normal, does this again a mimute later right before I pull in the driveway.
When I pull in I immediately get codes; P0353, P0352, P0351 and P1391.
I'm planning on changing both sensors tomorrow, I been reading about this all afternoon and every issue seems slightly different.
Is changing both the wise choice?
