    Random rough idle. Goes away with a little revving

    Anyone know what causes this? 2012 Expy. I'll be driving and suddenly the engine will drop in revs and idle really rough. Shakes a lot. It will immediately go away if I rev the engine a little. It doesn't happen often, but it seems like it's always when I pull into a driveway. I'm...

    Lunge/hesitation at low RPM caused by TPS?

    I had the motor swapped in my 2012 expy about 6 months ago. Shortly after the swap, I've noticed a sort of "lunge" and also hesitation when accelerating with light throttle from a stop through at least the first three gears - always between ~1300 - ~1700 rpm. I'll lightly press the throttle to...

    Manual gear selection

    Just had a rebuilt engine put in my 2012 Ford expedition. Trans only has 60,000 miles on it. I noticed that now, when I put the the trans manually into "3", it stays in 3rd no matter what. Whether I'm at a complete stop or mash on the gas pedal, it will not down shift. I need a sanity check -...

    Will not downshift while manually in 3rd

    Just had a rebuilt engine put in my 2012 Ford expedition. Trans only has 60,000 miles on it. I noticed that now, when I put the the trans manually into "3", it stays in 3rd no matter what. Whether I'm at a complete stop or mash on the gas pedal, it will not down shift. I'm almost certain...

    Multiple misfire after fill up - coincidence?

    2012 EL - my wife filled up the car at Costco and, within a few minutes/miles after driving away, the car start shaking like crazy. I drove out to see what was going on. Sounded and ran horrible. Initially, code showed a pending misfire on cylinder 3. I got it home and ran it a little more to...

    Shop claiming transmission "clunk" is the differential

    I recently put a used transmission in my 2012 Expedition EL. The transmission came from a reputable place (LKQ) and had less than 50,000 miles on it. Not long after it was put in, I started to notice that there was an occasional "clunk" from the transmission as I was slowing down, right when...

    Chasing a vibration

    2012 XLT EL Yeah, it's me again! So, I've been chasing a highway vibration on this vehicle for the last 6 months. I can feel it start ~60 and it gets worse the faster I go. I'll feel it through the whole car, the steering wheel, sometimes both at the same time, sometimes only one or the...

    Tranny stuck in 3rd - now i'm stuck in pocatello

    I went to start up my 2012 ford expedition today and the battery didn't have enough oomf to get it going (the battery is getting a little weak and I left my dash cam on for a few days while it sat). So, I grabbed a battery charger that has a setting for cranking the car. I got it started with...

    A/C Refill questions

    I'm planning doing a full recharge on the ac system in my 2012 XLT (back story on the vehicle below). Since I'll be pulling full vacuum and sucking everything out, should I add some PAG oil back in? If so, what kind and how much? I purchased it earlier this year and have been slowly but...

    4wd actuators or vacuum line?

    2012 Expedition - I've been noticing a clicking/grinding noise from my front passenger wheel (especially when turning) and, after watching a few videos, have successfully diagnosed it as the 4wd being partially engaged. While diagnosing, I found the it wasn't just the passenger side doing it...

    p2626 after 02 sensor replacement

    A few weeks ago, I got a p0155 (which is 02 Sensor Heater Circuit Malfunction Bank 2, Sensor 1), out of my '12 Expedition with approximately 230,000 miles. So, I replaced both upstream 02 sensors (good grief...what a pain that is :boxed:). Over the course of about a week, the problem was...

    Torque App Transmission Temp PID

    Has anyone successfully got their Torque app to give them transmission temps on their 2012 Expedition? The default options that show up in the gauge menu return no data. As I've been perusing the internet the last few days, it is my understanding that a custom PID and equation is required...

    2012 - Time for a transmission

    I bought a 2012 EL 4x4 from my friend who is a wholesaler. He got it at auction pretty cheap ($4200). It's got high mileage (229,000) and, as expected, has needed a little love but otherwise seems to be a killer deal. The transmission is on the way out so I'm going to swap it with a low...

    What is this body part called??!!

    I keep searching for replacement parts for the plastic panels/molding/whatever that the expeditions have on the doors and cannot find them. All my searches give me fender flares and other parts. Right here: https://www.dropbox.com/s/9v3nwxdly6uxflr/expedition.PNG What is the name of those...

    Buyer recommendations?

    I'm going to be buying an expedition in the next month or two. Most likely, I will be getting 2003-2004 model, but if I can find one in my price range, I will go 2005-2006. What kind of things should I look for that would be signs of a bad/good buy on these years? I'm mostly looking for...
