I've been gone a long time... I just haven't been able to afford the gas or risk the broken parts to go off-roading in a while, so I've avoided sites like this that make me want to go more than I already do. :dunno:
That said, I'm stumped. My Jeep is giving me trouble and I can't figure out what the problem is, nor can I afford to just have a mechanic mess around until he finds the problem! Here's what has happened... The check engine came on, so I took it to autozone and had them read the code: O2 sensor is bad it says - which wasn't surprising since I had replaced the other one a year ago so I have been expecting to need to replace the other one. So I replaced it and the light didn't go off, so after a while I pulled the battery cable and reset the computer. 30 miles later, the light came back on so I had autozone read the code again - o2 sensor again, so the autozone guy used his code reader to reset the code. About 100 miles later, the light came on again - but after another 30 or 40 miles, the light went off on its own. It hasn't come back on in a few days. During this time, I have been getting around 10-12 mpg (city and highway mix, but always short trips, AC on nearly all the time - historically I would expect to be getting ~15-16mpg) and it sometimes bogs down as though I were suddenly towing a lot of weight. This is almost always at half-throttle or less and opens up if I hit the gas, but occasionally even full-throttle feels awfully sluggish. This isn't all the time, and I haven't discovered a pattern to it, so I can't reproduce it at will. It doesn't just show up under throttle though - sometimes while idling it will get very rough and start idling very slowly (less than 500 rpm - it dropped to around 250-300 a few times when the AC compressor kicked in.) I don't want to take it to my mechanic until I can reproduce it so he can see for himself what's going on - but right now the only consistent symptom is bad gas mileage.
I can't afford to keep driving with mileage this bad, but I can't afford to fix things that aren't broken. I'm not a very good mechanic, but I can do most basic maintenance. I would really appreciate any help you might be able to give.
My Jeep has nearly 88k miles, with about 30k on the spark plugs. I think all other relevant info can still be found in my signature, though I'm sure I have failed to mention something important. I'm really stumped - I have done a quick search but I haven't found anything similar. I do tend to miss the helpful threads though, so forgive me if this is common!
TIA
