2000 Ford Expedition: jerking or lurching

Filed Jan 5, 2018 · Acceleration, Brakes · 251,000 miles · MN

Throttle feels like its sticking. The breaks feel like they get harder the longer you drive or use them. Its been extremely cold the last few weeks (air temp of -28f lows to -3f for highs). You let off the break from a stop sign or stop light and it will suddenly accerlerate by itself. Seems to happen anytime after 40mph, even if you slow back down to 10-15mph it will accelerate back up on its own, up to as fast as 65mph!) I need to downshift and ride brakes (which are hard as a rock!!!) to keep it from excelling though town and to try to keep the rpms at bay. When coming to a stop and turning its hard to steer and it makes jumpy/jerky movements forward when brakes are applied. When vehicle comes to a stop the rpms skyrocket until you shut down the engine. If you havn't given it enough time before you start it again, the engine and rpms soar up again. Things we've tried with no luck are, disengaging the cruise control, replacing the spring under hood where the throttle cable is. Thought maybe it was stretched and not depressing fully to alow deceleration. After that we replaced the throttle body itself. Again, no luck on test drive. You can hear a click/ping in the pedal and see it come up once truck is in park, give it time. Pedal seems to be partially depressed and there is play. Have tried to stick foot under the pedal to try and get it to disenge. Worked the first few times that's also why thought it was the spring. No longer works to do that. Can seem to hear a difference either in motor or trany, acting as if it's working harder when it seems to take control of itself. Started happening 12-24-17. Been to the shop many times with no answers as to why this is happening. It's very scary and dangerous! After reading about all the others this is happened to its hard to imagine that there hasn't been a recall or at the very least an answer yet!

While I pulled in a parking lot after freeway driving the throttle sticks. This only happens in lot temperatures. This makes the vehicle unsafe to drive. You have to push the brake extremely hard to stop and the moment you remove your foot from the brake the vehicle speeds up. When this happens on snow cover roads the ABS kicks in. When the ABS releases the brakes the vehicle jerks forward 2 to 3 feet. This is a major safety issue making the vehicle unsafe to drive. Ford has issues a tsb on the problem (tsb 01-21-5) suggesting a pvc repair kit. The problem is not being caused by a defective part, it is a defective design allowing moisture to enter the system from the pcv and ice up the throttle plate. This needs to be a recall.

The front sway bar linkage bolts rusted and broke on both sides. I only had 47k miles on my vehicle. I noticed the vehicle jerked after hitting pot holes almost being uncontrollable if I was not holding on the steering wheel with both hands.

While stopped at a stop light behind other vehicles, my vehicle suddenly accelerated pushing me into the vehicle in front of mine. Applying full pressure with both feet on the brake pedal, my vehicle continued to lurch forward into the vehicle in front of me and pushing it into another vehicle. I had to put my car into park and shut off the engine to get it to stop lurching forward. It must have lurched forward 3 or 4 times into the truck in front of me after making initial hit. We've noticed where the idle would increase in the past but nothing that seemed to be dangerous in any way. We had a 98 expidition that would increase in RPM's and lurch forward and had to take it to the dealer for repair. That driver in the truck in front of me complained of neck problems and had to be taken in an ambulance.

On 5/3/01, at approx. 2:40 pm, I was driving north on 10th(amsterdam) ave in manhattan in relatively light traffic at approx 20-25mph. As I crossed the intersection of amsterdam & 58th st, my vehicle suddenly began to accelerate uncontrollably toward a high rate of speed. Standing on the brake pedal with all my weight only managed to slow the vehicle to perhaps 30mph, with engine racing as if the gas pedal were pushed to the floor, when obviously there was no pressure being applied to it at all. As I crossed the intersection of 59th st, I managed to gently ease the gearshift lever into neutral. This combined with my continuous pressure on the brake brought the vehicle to nearly a stop, with the engine still racing. The instant forward motion ceased, the vehicle lurched into reverse, with the gearshift still in the neutral position. The vehicle then began traveling backwards, once again at the same high rate of acceleration. Still standing on the brake petal, I switched the ignition off. A split second second later, the right rear quarter of the vehicle slammed into an ambulance, at a speed of perhaps 30-35 MPH. From the beginning of the incident until the end, I travelled about 500 feet forward and 120 feet in reverse, continuously maintaining maximum pressure on the brake petal. My vehicle impacted the ambulance at the strongest part of its structure, the curved, steel reinforced front corner of the ambulance "box". Had the ambulance been 2 feet further back, the driver would have been killed instantly. There were 3 emt's in the front of the ambulance, and no passenger or personel in the rear. All of them saw exactly what I have described, and I am sure their statements about the movements of my vehicle will corroborate my description of the accident. I was extremely fortunate to impact a vehicle with enough mass to stop the momentum of my 2 1/2 ton SUV. Had I impacted smaller passenger vehicles or pedestrians, many people could have been killed.
