    RPMS surging on acceleration

    Jerking when under 1000 RPM

    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...

    RPM fluctuations at idle. Normal?

    Since getting my scan tool, I’ve noticed that my rpm’s decrease and increase slightly in park, and in drive with the brake on. Does this happen to anyone else? It’s not a huge change, but they do move up and down by about 10 rpms every second. This was over the course of a minute:

    Vibration/Noise at specific RPM

    Hey guy, My 07 Explorer (4.6) has been making this new sound recently. Whenever I hit 3900-4100 RPM I get this Vibration that I can feel through the petals and a little while in my seat. Its a deeper tone but it does sound metallic. I can get it to happen in every gear so I'm not sure if its...

    High RPM / 3rd gear jerking

    My girlfriends 1994 ford explorer (130k miles) is having a problem that will not allow her car to pass a smog test.

    Drop in Rpm on startup

    Hey guys, Ever since last winter, I had an issue that whenever I would start my truck, the rpm would climb as usual, then drop suddenly and climb back up to what I consider to be a normal rpm range (1000-1500). This problem got worse when it got pretty cold like below freezing temperatures (I'm...

    I have a 2003 Explorer, with the 4.6 V8. When driving a steady pace, all is well. But when I get on it to pass someone, or put the truck in passing gear, and then I come to a complete stop at a light or whatnot, the truck's RPM's get so low that the truck shakes pretty hard for a few seconds...
