Slight run down of what I've had going on the last couple weeks. So hopefully get a full detailed picture.
Got a check engine light 1.5 weeks ago that when it was scanned it showed for a O2 sensors. Been driving like that till I get my new exhaust. Earlier this week I had my battery volt meter go from about 14v to 19v as I was driving to work one afternoon. It lasted about 10 minutes then dropped back down to 14. Yesterday out driving and geocaching I turned my jeep off for a few minutes and when I turned the key, my jeep turned over weakly and bogged and died. I turned it off and then on again and this time I pushed on the gas and I kept the rpm up at 1k and after I let off the gas it went back to normal, Oddly though the check engine light disappeared?!?! So I put in reverse and backed out and as I let go of the gas to shift it just died on me. Just stopped running. Started it again and it was bogging again till I pushed on the gas then it settled itself. Took it to O'reillys and had it scanned and no codes were shown?!? Even my O2 sensor code was gone. Did a load test on the battery and it was great, did a test on the starter and alternator and both showed to be just fine. Now later in the evening, driving home my check engine light came back on.
My thoughts were the idle air control sensor as I've known idle issues from that before but the voltage spiking and check engine light disappearing and reappearing has me worried it might be more than just that. Is this just a case of coincidence with the other symptoms and a failing iac or does all this add up to something bigger?
