    Whenever I slow down and the rpm is under 1000, no pedals being pressed, the RPMs start to go up and down and at sometimes can hit close to 0 and the car feels like its jittering. At higher speed, the RPMs are normal and have no problem driving. I have a 2015 PIU with 120k miles. Do any of these...

    Need advice on 2006 Ford Explorer Eddie Bauer 4WD

    A few months ago my Explorer started hesitating at 45-50 mph. Below or above that it cruised fine. I took it to F last month to get it checked out when it seemed to get worse (hesitating more at lower speeds, especially uphill). They said it was the transmission. I took it to my transmission...

    Not a good buddy, rather a decent acquaintance. had me attempt to do plugs n' wires on his '01 explorer. With not insignificant effort, rusty motorcraft plugs, that likely ain't seen the light of day since clinton, and burned solid plug wires, were extracted with severe prejudice. To make an...

    On the 4.6 3v anyone ever run into the threads and hex piece breaking off, but everything else staying intact? Man I went 5/8 in changing plugs (73k miles). One broke the usual way and I got it out with the Lisle tool, but two look like they got undressed for the evening and took off their...

    Massive surging issue

    Hey all, I'm getting some crazy surge-like behavior from my new (~1500 miles) 2014 Explorer Sport. It feels like I'm hitting a rev limiter, and unlike anything I've read about on here. Other surging issues on here seem to deal with loss of power, and usually at a high speed/rpm. This is not...

    I will be replacing my spark plugs on my 2001 Explorer Sport (4.0 L - SOHC). The guy at Auto Zone say's to use the more expensive platinum plug's since that’s what came from the factory.
