Q: Engine Missing on 2006 Ford Explorer

I have a 2006 Ford Explorer, when I'm driving down the road at 50-60 mph the truck hesitates. When I go up hills it hesitates, when I go to give it gas to pass someone it hesitates. We have done a complete tune-up, plugs, wires, oil, oil filter, fuel filter and it's still doing it. It is getting worse everyday that I drive it.

start with a basic compression test. possible injector issues if you replaced all the ignition parts.

i heard the same thing mines doing it also first they told me a throttle position sensor replaced still doing it now tomorrow am replacing the EGR valve i'll let you know if its fixs it
Thanks...I replaced all the plugs and wires 2 weeks ago and it's still missing. Not as bad, but it's still doing it. My light isn't on so everyone is acting like they can't tell me what's wrong with it cause my light isn't on.
Had the same hesitiation/miss problem on 06 Explorer with V8. Dealer diagnoses as two bad coil packs (cyl 1 and 5). Estimated $500. I paid the diagnostic fee, purchased coil pack from Autozone ($40 each) and inistalled in abotu 10 minutes. Problem solved.
I had the same problem and they replaced the transmission first.....under extended warranty and then it was miss firing which they finally resolved. Very fustrating!
mine doing the same. have changed throttle body assembly. this cured it for a week then it started back. trying maf sensor now...freaky stuff. dealer is baffled.has anyone fixed this yet? it happens at 2300rpm in overdrive every time pulling a grade uphill..all the components run off a voltage reading. I think its apparent that a lot is going on at that rpm. Its the rpm most folks drive at on highways. it is the same time overdrive locks in. It really isnt a miss per say more of a flat spot where the computer hesitates on what to do shift or dont shift. excellerate or not? anyone got a clue? And there is no engine codes showing !!!!!!
