    1997 4.6L issues HELP with ideas please

    I had the same symptoms that you’re describing with my 99 5.4. I’m not sure if the 4.6 has it or not but my 5.4 has a vacuum line from the PC valve to the rear of the intake. The rubber coupling connecting it to the intake deteriorates and the engine runs horrible if it even runs at all. It is a...

    Transmission will NOT stop leaking.

    Maybe the other half is just feeling like messing with you and every now and then goes out and dumps a quart under there to get a good laugh at your expense. Surely you’ve done something in the past to deserve this. LOL

    Can a fuel pump go bad after Expedition sitting for 6 months?

    What do you mean by it begins to turn over? Does it spit and sputter a little or does it actually fire off and run for a couple seconds? If it is a fuel problem, it should fire off and run briefly when you spray starting fluid into it. Are you spraying the ether directly into the throttle body...

    Brakes VERY soft despite bleeding and new MC

    It probably would. The gravel road track works every time so I don’t worry about it too much. I was just replying to the original post to let him know that this trip might work for him too seeing as nothing else seems to have worked. Thanks

    Brakes VERY soft despite bleeding and new MC

    I have had this problem with my 99 5.4 XLT after I bled the brakes. What I did after much googling was took it out onto a gravel road and slammed the brakes on at 10 mph, then at 20 mph , again at 30 mph, 40 mph , and finally at 50 mph the abs kicked in and started working. Up until then they...

    Brakes VERY soft despite bleeding and new MC

    When did the problem First show up? Was it fine and then you did work on it or did you do work on it and then the problem arose?

    White Smoke after IAC cleaning

    I hope that’s all it is. It took me a lonnnnnggggg time to figure it out. I thought it was a blown head gasket. And compression readings were all over the place. Let me know how it turns out.

    White Smoke after IAC cleaning

    You didn’t mention the year and Engine which would be helpful. Does your throttle body have a disk about the diameter of a quarter protruding from the passenger side that the pcv hose mounts to along with a small coolant line coming into the front and Another attaching to the rear? Can you look...

    1999 5.4l Expedition PCV help

    I have a 99 expy with the 5.4L and I have had to change that PCV line setup. When it develops a leak at the rear of the throttle body you'll get a code ( sorry, I don't remember the number) and engine idle will be very rough if it runs at all. My guess as to why someone would have capped it...

    Intake manifold gasket?

    When it was running was it blowing steam out of the exhaust? The reason I ask is because I have a 99 5.4 L that I thought had blown a head gasket. It has the aluminum plenum ( upper portion of the intake manifold ) and a plastic lower portion. After replacing the heads, gaskets and the intake...

    Clicking Rattling mirror

    I had the same problem on my 99 XLT. If I remember right from the insides of one that I saw at a junkyard, there are some small plastic tab type fasteners that hold the pieces of the mirror case together in there that cause this annoying problem when they get broken. I have no idea how to fix...
