    P2198 and misfire on all driver's cylinders

    I'm wondering (after doing some digging) if it might be a plugged cat on that side. Seems that could cause misfires and a rich / hot O2 sensor.

    P2198 and misfire on all driver's cylinders

    2005, 100K on the clock. I've only owned it for the last 5K so I don't know if the plugs are originals or not. Based on all the other crap that has been wrong with it, I have no doubt that they are and need to be replaced. I just have a hard time understanding how *all* of them on the bank 2...

    P2198 and misfire on all driver's cylinders

    Sorry, 2005 Navi. Biggest POS and far and away worst vehicle I've ever owned. Nothing but problems problems problems. At this point I just want to get it running right and get rid of it. I firmly believe it is cursed.

    P2198 and misfire on all driver's cylinders

    Hey all, the latest gray hair from my Navigator. Running like shit, misfiring, reading codes P0300, 305, 306, 307, and 308. P2198 indicates an O2 sensor issue on bank 2. Before I tear into it, I'm thinking a bad O2 sensor could cause multiple misfires? I know a rich cylinder could hose an...

    2005 Navi - heat and A/C blows from ALL vents

    Haven't gotten to this yet, but thanks for all the suggestions and help. The POS decided to throw misfire codes on #7 & 8 the other day, so I'm sure I'm going to be replacing COPS. I swear this truck was built on a Monday....

    2005 Navi - heat and A/C blows from ALL vents

    Hey all, having a issue with my 2005 Navi. The heat blows hot, the A/C blows cold, but it all comes out of all the vents - defroster, dash vents, and floor, no matter what the auto climate is set to. I'm assuming there is a widget that directs the air to one vent or another, but I have no idea...

    Help me Obi-Wan Fordobi, you're my only hope - mirrors gone to the dark side...

    Funny part is, it does not always happen. Seems much more prevelant if I hit unlock twice, to open all the doors. If I'm just hitting the driver's door it's more like 50/50. I think once I have some time I'm going to pull the mirrors apart and give them a good cleaning. Found out that the...

    Help me Obi-Wan Fordobi, you're my only hope - mirrors gone to the dark side...

    Howdy all, hoping you might be able to help diagnose an issue with my '05 Navigator (not an Expedition, but hey it's close ;) ). The 'gator has memory and power fold mirrors that I'm guessing are identical to the one fitted to EB Expeditions. On my truck, they are misbehaving a bit...
