    Revealing pictures of an NSS

    If you've ever wondered(and who hasn't?) what a Neutral Safety Switch looks like on the inside, here's an example from my wife's 2005 F150 5.4. I replaced it because of a couple of times when she was out and the truck wouldn't start in Park, only in Neutral. This is my all-time least favorite...

    Door Ajar sensors

    I'm going in circles chasing an issue in my 1999 5.4. Even after a hard reset, the scanner consistently shows B1318-Battery Voltage Low and B1323-Door Ajar Warning Lamp circuit failure. The battery is new, alternator is fine, and the lamps always turn on and off as expected so I removed the...

    1999 5.4 - first time using smoke machine

    So I got an Ancel S3000 smoke machine(thanks Hamfisted) and have tried it out a couple of times. Yikes! My 1999 doesn't have any codes but this device smoked out a few problems that need to be dealt with now. I tested at the brake booster hose, oil filler neck, coolant reservoir, exhaust pipe...

    Suspicious: shop replaced hub assembly, now says bearings need replacing

    This concerns my F150 but I'm posting here because I'm familiar with many of the responders in this forum and it's a generic question. Last April, the local dealership performed a brake service - machined the rotors, replaced pads, etc. They also said the left front hub assembly was bad and...

    Cleaning throttle body to EGR valve passageway

    Picture of 5.4 throttle body before cleaning it 22k miles ago. The TB-EGR passageway has never been cleaned and I'm assuming it looks as messy or worse. So, even though there's no codes or other trouble indicated, would you clean it anyway?

    A Yellow '99

    One day's accumulation of pine tree pollen. Can't be good for the finish but rinsing it off just makes it stick better so I've been using my ShopVac blower.

    Keyless keypad failure w/ picture

    My 1999's keyless keypad quit working several years ago but I quickly replaced it last week. Thought it might be useful to somebody to see what caused it to fail.

    1999 - Can crack be fixed without welding?

    My 1999 developed a stress crack in the area where the driver side liftgate strut connects to the frame. Over the last year+, I've contacted almost every shop in the area that mentions welding and none are interested in the job. So, how to get the liftgate functional again? Could I fasten a...

    1999 5.4 - not bad u-joint?

    It's hard to describe a sound with words and I don't think this forum allows video attachments so here's a YT link. rear u-joint Going into gear, my 1999 5.4 has been making a grinding noise that I couldn't ignore any longer. After researching for a while through the usual sources, my...

    How to interpret 1999 scanner data?

    My scanner's on-board monitoring report is formatted like this. OBD2 was young in 1999 so is this info even relevant? If so, where can I match the numbers to a name?

    New member, restoring 1999 Expedition, Aiken, SC, USA

    Hi, I'd like to properly introduce myself to the forum and maybe participate in some of the discussions. A decade or so ago, for economic reasons, I began maintaining my 1999 Expedition EB 5.4 and my wife's 2005 F-150 FX4 5.4. There were a lot of things I didn't know but I can say now that...

    1999 Expedition 5.4 EB crack where liftgate strut connects to body

    A few days ago, I noticed what looks like a stress crack where the left liftgate strut attaches to the body. I would appreciate a response from anyone who knows what it means and what to do about it. Is it cosmetic or structural? Can I ignore it or do I need to panic?

    Is it No Code for my 1999?

    My 1999 EB 5.4 is burning a lot of oil and starting to run rough and I'm wondering if it's worth putting any more money into it. Wondering because I don't really know what I'm looking at other than heavy oil residue around the valve covers and other nearby locations. The entire area behind the...
