    My last hope on my rough idle

    Hello everyone, as the title states this forum is my last resort before I fork over the cash to a real mechanic. (video link at the bottom if you care to see it) First, the issue - the vehicle has a rough idle that gets worse as the weather cools, (the engine temp doesn't affect it) at its...

    Rough idle stall

    Just bought a 2014 limited expedition drove fine during test drive and for 24 hrs afterwards. The next day started rumbling and shaking like a cam phaser issue (killed my 09 I had) no rattle. Scanned the codes came back cam sensor issues (p0015,p0025,p0365,p00369) . Replaced the sensor topped...

    2003 5.4 2 valve rough idle, hesitation when stepping into it and low power no codew

    I have an 03 expy with the 5.4 that has a rough idle, low power (0-30 in 20 seconds) and no codes I replaced the oxygen sensors, MAF sensor and the throttle position sensor. Could this be timing or is it IAC? Is it something else?

    IAT Sensor Trouble

    I got the PO113 code with the rough, idle/lean condition and rough acceleration symptoms a few days ago. This came after changing my defective PCV which smoothed things out considerably. The code is accompanied by several misfire codes that change cylyinders at random (Mode6 shows random counts...

    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...

    My 2014 Expedition has just developed its first engine problem after almost 96,000 miles. I guess I should feel lucky...but not so much. :-) I had an oil change and 99 point check done at a local Ford dealer on July 11, and all was OK. That was followed by some suspension work and an idler...

    Catalytic Converter Replacement

    After dealing with a ton of no-start, misfire, and excessive rich conditions, I believe my passenger side catalytic converter is done for. My 05 Expedition EB 5.4L 3V 4x4 takes some time to start. It cranks for a good 5 seconds when cold starting and has a rough idle in drive gears and...
