I have 02’ 4.7ltr with 265,000 miles.
I recently had 2 codes come up. P1682 and P308. I have a partially clogged cat which I’m waiting for funds to replace them all.
I’m wondering if the back pressure from the exhaust caused my P308?
Anyway, I picked up the codes on the way to work one morning, on the same day on the way home the Jeep was working on overheating, but I was able to catch it and bring the temp back to normal with running the heat full bore. I had a couple of errands I had to do before going home the Jeep felt like it ran fine but I kept the heater running the whole time.
I’m not too worried about the P1682. The voltage gauge said the alternator was charging fine. I will have to run by Autozone to get it tested or just buy a spare so when it goes I slap the new one in and get wherever I was going. I have currently stopped driving the Jeep at least until I can get it fixed.
There is no water in the oil, So I’m not sure if it’s a blown head gasket. The last time I got a miss fire code it was a head gasket on the driver’s side, but the engine also hydro-locked (dead give away). With the overheating I just figured that might be the issue.
Any ideas where to start once the cats are replaced?
