Ford - Contour :: 1999 - Jerking While Driving Accelerating Slowing Down
Jul 23, 2012
I was driving the car yesterday and was getting on the highway ramp and stepped on the gas and car went crazy. It started to accelerate and decelerate by itself. I had no control of the car whatsoever. When driving at 0 to 40mph no problem so far, but anything over this car will jerk, like it's changing gears by itself, 'going fast and slow.'What is this? Do I need a fuel filter, or plugs or what? I don't know when the last time I changed anything the car mileage is 135,000

Almost everytime I drive the car for more than 2 consecutive it acts as if it drops a cylinder..running rough. The next day it will run fine until 2 hours go by...and so on. I have changed plugs wires and coil pack.... 4 cylinder .. automatic

About a month ago my Lumina (1999 LTZ 3.8L 85,000 miles) started jerking a little bit while slowing down almost like I was hitting the brake too hard and after 2 days of it the car would shut off while braking toward a stop sign or while idling and would to this without the jerk, no warning. I replaced the throttle position sensor hoping this would fix the problem, it did nothing. Soon after this the engine would jerk really bad while driving and shut off even during acceleration, the service engine soon light came on during this time. I took it to a local mechanic who said the error code was for a faulty mass air flow sensor, so that was replaced. This made things a lot better, no more dying or jerking while driving but there was a new problem.
When starting the engine cold no issues, when starting the engine warm after sitting 20-30 minutes it would shake and the RPMs would fluctuate by 300-400, but once I put it in drive and started going it would drive smooth. The service engine light came back on so I brought it back to the mechanic. This time they said the fuel pump wasn't pumping enough fuel (low pressure?) and it needed to be replaced so I did that but it created a new problem. When I would start the car cold the RPMs would jump way up to 2000 then down to 0 or it would jump to 2000 then down to 500 then up to 1500 then down and so on until I put it in drive.
So I brought it back again and they replaced a gasket around the fuel pump, put a new idle control sensor (i think?) and told me to turn the key to on, listen for the pump to stop pumping fuel and then start the car, I have never had to do that before all these problems. This worked fine for about 2 weeks and now I am back to the car shaking while starting it warm like it did before the new fuel pump and the service engine light just came back on. But again, once I start driving it runs nice and smooth like there are no problems.

I drive 07'es350 and I have felt jerks while driving usually when accelerating or slowing down from speed. Did check with dealer before for transmission after analysis by technician he said it is perfect, recently read on internet and saw fuel filter can be an issue but when called the dealer he said filter is in gas tank and it is lifelong. Not sure what kind of diagnosis I should do to find the issue.

I have a 4 cylinder 2000 Ford Contour 133k miles
I've only driven the car for about 2 months, Ive never had an issue with it until yesterday other than an occasional hard shift when driving the car hard. Yesterday when I dropped the car in drive it wouldn't pull at all, I sat in my apartments parking lot continually revving the car high in drive but it wont do anything, its like the car is in neutral. Reverse works and I can drive by manually shifting from first to second and then putting the car in drive, but if I put it into drive before reaching 3rd gear it jumps back to neutral.
I checked the linkage, and the lever it connects to on the transmission; when put into drive the position of the lever coincides with the neutral position. I called a few local transmission shops and they diagnosed is as a broken sprag, but from reading online it seems like it could be a clogged transmission filter or a faulty transmission range sensor. Prior to this issue I would sometimes here a whistle coming from under the hood when driving, I didn't know until today that a whistle is indicative of a vacuum leak, but wouldn't it throw on my check engine light? I have checked my transmission fluid, its at the correct level and is a nice cherry red, it doesn't have any bad or burnt odor.

I have owned a 2007 2nd Gen Prius for about a month in a half. I love my Prius although I purchased it with high miles (just under 200K) I felt a little adventurous and took it on a rather lengthy trip from Ohio to Nebraska and then to South Dakota and back home) a few weeks ago and I've noticed a few things since.
Before this trip I could let my car coast down slight grades or hills with no issue. The car just coasted like normal which save gas of course. Well now on slight hills it feels as if the car is down shifting. It actually slows itself down slightly. On steeper grades it will still coast but up until a few weeks ago I could literally coast on a slight grade. Not so anymore.
Also when I accelerate now sometimes when I lift my foot off the accelerator it bucks or jerks. It's not very violent but noticeable. I didn't experience any of these issues before the trip. I was wondering if the rocky back gravel roads of Nebraska could be a contributing factor in any of this or perhaps the steep hills of Rapid City South Dakota (SD was when I first noticed the reduction in coasting)
I've been in to see the Toyota Service department In my area and of course they told me that, "Those Prii just drive like that". I refuse to accept that since I am very sensitive to changes in drivability in any vehicle that I own and I know that my Prius operates and feels differently than it did before.

Mostly occurs at high speeds and climbing hills. Could it be a transmission problem? Or a fuel pump?

Just purchased a 2001 Ford F150 super crew lariat v8 4.6/5.4 2v OAD at 156k miles, iv had no problems with it until I drove over the pass and after 2hours of driving my truck started to jerk when I accelerate between about 40-60mph. I don't experience any other problems over 60 it runs smoothly and in town under 40 it also runs smoothly, no check engine light. The next day is still continues to make a jerking motion, which feels like from the rear.

Car started to jerk when 30mph and up. I changed the fuel filter and oil. Car was ok for a couple of days, however it started to make lound sounds, needing a muffler. i took it to the shop and it needed a flex pipe. All was well for a day, than the car had trouble staying started. It would drive fine, but when you are stationary at a light or stop sign the car wanted to stop. Took it to the shop and the guy said it need a pvc pipe/hose.
The guy told me that the pipe had rotted and it was at the back end of the engine. Car was good for several days, however it now started back jerking at 30mph and up. It will not do it all the time but sometime. It's like the cruise control is going on off. You can step on the gas, but the car will not go any faster, 'just stay the same speed.' When speed is drop it will be ok, but will jerk for a period of time and then stop.

I have a 99 Ford Contour that sporadically refuses to start. The engine will turn over (is that the right term?), but it won't "catch," for lack of a better way to put it. It seems to happen more frequently when the gas gauge is at 1/4 of a tank or below. A dealership told me it was the fuel pump need repair (more than the car is worth), but a second opinion from an independent garage says it might not be the fuel pump.
(Though they don't know what is causing the issue because, of course, it never behaves the same when the mechanic drives it). The second issue, which may or may not be related, is the vibration in the car. It happens only if I turn on the AC or heat. And I do mean shake - it's very noticeable and loud. The motor mount has been checked and that's not the issue.

I have a 2005 F150 S Crew and have been maintaining it regularly. I started having a jerking while accelerating lightly or in between shifting then the overdrive light comes on and then flashes trans fault on dash. I took it to the local tranny shop who fixed the problem however about a year later it started doing it again. What the problem could be before I have to spend another bucks?

In stop and go traffic , it happened twice today, I slow down almost to a stop and accelerate, the RPM goes way above 5000, it seems it holds in gear 1 or 2 can't be sure and does not want to shift. I had to shift using paddle shifter. Is this a real problem or am I doing something wrong. ?

My 2005 Accent began making an odd clicking sound about two years ago when I would decrease my speed, not using the brakes. It wasn't loud, just annoying. It went on for some time until my car went into the shop to have the alternator replaced. I explained the noise to the mechanic and they checked it out. They explained they added some type of cleaning fluid somewhere under the hood, and the sound was gone. I was thrilled.
Last year, the sound returned again. Annoyed, I began saving to bring it in to the shop again. In Feb 2013, I had my timing belt and water pump replaced because my mileage of course called for it. The mechanic said he could not hear the clicking sound I was reporting (I really didn't see how.)
Two months later in April, my car decided to die on me and after 5 months I just recently got it up and running again. My differential and transmission were both completely rebuilt. Also, my CV axles have both been replaced. Now that I have my car back, the clicking sound is louder than before and also now happens when I accelerate as well. The faster I go, the faster the clicking gets until it eventually stops. When I slow down, the clicking starts again until I hit my brakes.
I want to take my car and get this noise silenced once and for all since they didn't hear it when my transmission was done last month. What fluid may have been added to what part 2 years ago when this was handled initially?

I just bought a new Accent. It seems to slow it's self down at low speed when not accelerating. In other words, it does'nt coast freely. Could this be a sticking brake caliper or a transaxle problem? Could it be related to the slippery road condtions feature on/off?

This is in regards to my daughters 2009 I4 Sonata. In cold weather, like we are having now in Chicago. After the car is sitting all day or overnight, it will jerk (nice technical term) when accelerating until the car warms up. What is the problem is and how to resolve it?

Are the mounts on the engine not tight enough? It feels rather strange. My dad's Ford Explorer doesn't do that. I feel like I'm driving a car with a manual transmission that needs to have dogbone bushings and mounts upgraded. How do I bring this to dealership's attention without appear like a complete loony? They like to give the "Could not duplicate" response when there is an obvious symptom.

I recently had several parts replaced on my 02 Dodge Intrepid within the last few months, including the brake lines, motor, gas lines, sensors, spark plugs, and a few rusted parts that were busted while the motor was being replaced. I have had my car back for a week after most recently getting the gas line replaced. (My gas line froze the same day I got it back after getting the motor fixed!)I haven't had an issues until Saturday morning my engine light came on.
I drove it throughout the day no problems, then I stopped at a red light and had trouble accelerating when I went to turn, my car then jerked forward and and ran seemingly normal, but the problem continued every time I stopped or slowed down. After 5 minutes or less of this I parked my car and called my mechanic. After a half hr I restarted my car and circled the parking lot with no issue and headed to a friends nearby. The stalled accelerating and jerking began again until I couldn't accelerating at all without waiting and restarting my car, and then finally there was no moving it at all.
I had it towed this morning and was told I had no transmission fluid. After replacing the fluid my car was driven to my house without an issue, so im assuming I didn't blow my trans? Several hours later, I went to start my car and there was a large amount of red fluid under the front of the car by the bumper and it wont move once again. Obviously I have a leak, but I don't know if the leak was the cause of the initial problem or if the problem caused the leak.

I have a 2009 honda accord, v6, auto, 46k. It has recently started to chug, most of the time, not always. I feel it in the gas pedal. Kind of a jerking, hesitation chug while accelerating. It only chugs between 20-40 mph, disappears after that. Someone suggested a spark plug problem, but I can't imagine it's that since it disappears after 40mph. Could it be a transmission problem?

My daughter's 2004 Camry V6 has been hesitating when starting from a stationary position or when accelerating after slowing down. Dealer has been having hard time identifying cause but thinks it is an oxygen sensor. Had one sensor replaced last fall when light came on. Tech Rep says there are four sensors. At least one is bad but the other two sensors may also be bad. Is there really four oxygen sensors in the 2004 Camry? Would this cause the hesitation when accelerating?

Like the title says my truck has been stalling while driving. Accelerating or cruising it dies for a second, two at the most, and then just keeps chugging along again.
I thought i'd fixed the problem last year when I did injector O-rings and 50 cented my UVCH. It hadn't done it since, until two days ago. Started out with a two good solid stalls while gently accelerating up hill. I had thought maybe my fuel pickup foot had finely given up the ghost because I was below a quarter tank. But I filled her up full, and then she did it again about 50 miles of driving later.
I didn't catch the first four stalls on my torque app, because I'd just recently decided to stop logging every trip, with the thinking that it had been half a year problem free, why keep logging waiting for something that isn't going to happen. I did catch the 5th stall on the torque log. But I'm having trouble trying to figure out where it happened in a 30 min log.
First question where would yall start in tracking this thing down? Next what data actually should be logged? I think I've got some extra stuff in my logs that isn't necessary, and is maybe bogging down the system. I get one data point per second resolution on my logs. Are there ways to improve the resolution, will getting rid of some PIDs work?
Lastly I need to attack this thing smartly, without throwing time and money at unneeded parts. I had surgery and I've been out of work for 3 months and I'm looking at another 6 before I'm making money again, and there is no unemployment for the self employed. Also I only get 3-4 light weight upright hours a day to work, exceed that and I'm back on the couch battling swelling for a week.
Also is there anything I can do while driving to "flag" the stalls so I can find them more easily in the logs?
