    2007 Ford Expedition Engine popping loud, please help?

    Didn't think about the exhaust manifold studs. I will look at that this weekend. So everyone can see below here is what I have done this past weekend. It has not improved yet, but this far... Figured I needed to fix anything that tossed a code. The only codes were a number 2 misfire [get...

    2007 Ford Expedition Engine popping loud, please help?

    The #2 #5 plugs had to be replaced recently. I assume all plugs are wearing. I will swap a couple around to see if it chanced it first. I assume if the plugs are burnt or work it will cause spark knock/detonation

    I appreciate the help here. Would not have thought the O2 or Converter would cause such spark knock or detonation. Maybe replacing the O2 sensor will correct it.

    2007 Ford Expedition Engine popping loud, please help?

    So I ran codes, here is what it came up with as the only code. P0430 Generic. Catalyst System Efficiency Below Threshold (Bank 2) - Wouldn't that be an oxygen sensor on the passenger side? Not sure if that would have anything to do with my problem. Thoughts?

    2007 Ford Expedition Engine popping loud, please help?

    I purchased the plugs n coils from Ford. They are Motorcraft parts. I figured since these plugs were such a headache to replace, wanted to get the stock ones from Ford. The two I just replaced the boots looked great, but the spark plugs were pretty worn for sure. I have never had this...

    2007 Ford Expedition has a ghost somewhere.. Please help??

    When it acted up last week I did put it in N and tried to start as well. Nothing happened just as it was in park. I have my Voltmeter and will test the starter next time. The neutral safety switch was something I was looking at replacing. Also, I tried to find under the dash the linkage...
