Ok, here’s a good one. Bought the jku to tow behind rv. It runs great, good mileage, has 213 k miles, all stock, no hop ups.
All the issues started with an oil change at a quickie place. They used the wrong oil filter. Started throwing all kinds of codes. Replaced with the correct oil filter, took it to my local mechanic.
Replaced plugs, injectors, had rodent damage to harness with bad patch job, replaced factory harness, replaced with factory injector harness, replaced cat converter (both), replaced o2 sensors, replaced temp sensor, oil pressure sensor, throttle body , basically everything that need’s to be replaced.
Have a small leak at rear main seal, repairs coming soon. Here is the issue. The cats and o2 are still throwing codes. Cel light won’t go out. Disconnected battery, light goes out for awhile , comes back on. Tried to erase codes with JScan , no luck. O2sensors are working.
Jeep runs great, all recalls have been done. No coolant or oil leaks from engine. Just the rear main seal. No issues with the “ticking”.
Any one have any ideas? It’s driving me crazy. Please help. Thanks.
