I have a 2011 Chevy Impala. When accelerating from a stop it will frequently stutter then jerk forward. The first time this happened I thought someone had rear-ended me.
I've been to the dealer several times about this however they say they cannot isolate the cause. More importantly I can't seem to get the vehicle to repeat this problem when I've brought it to the dealership.
I have a 2002 Chevy Impala driving it in the city of Chicago. It's recently had the oil changed, and the transmission fluid flushed and filter replaced. This car was mine before I went off to school, and I meticulously maintained it for three years, and then my step sister inherited it. She drove it for two years, and then it sat in the driveway for a year and a half. It's got about 175,000 miles on it.
Problem: Every time I start to accelerate past 25mph and get around 2000rpms, the car starts to give out, sputter and jerk. It starts to drop off right when it should be shifting to second gear. When on the highway, even if I floor the gas peddle, it won't accelerate normally, but instead just crawls slowly to higher speeds.
It will eventually reach the higher speeds, but it takes about 5-10 minutes for it climb up from 25mph. I don't know enough about this level of car trouble to make a diagnosis myself, and would like an estimate of the cost for repairs. Also the car is getting around 19mpg on the highway, which I need to improve if I'm going to survive the $4.50/gal of Chicago gas. I'm hoping that fixing this problem will take care of that as well.
I'm getting some vibrations from my '06 2.0T. The car tries to jerk forward at a dead stop, RPMs jump about 100-200RPM. It kinda feels like stalling a manual transmission, only milder. The car is burning a bit more oil than it should.
Many claim it could be a faulty PCV Valve. Since I'm a little on the broke side and my car is out of warranty, what should I look for to tell if the valve or the hose is faulty?
I recently purchased a 2005 Camry XLE V6 (100K miles). Its in great condition and no issues except I am observing this:
-> When I come to stop (like at a stop sign), just before coming to complete stop, there is a slight forward jerk. When I come to stop slowly and smoothly, there is no problem.
the faster I come to stop the more severe is the jerk. I tried to search for answers on the web, one possibility is bad solenoid in the transmission.
I have an 03 vw Jetta 1.8t with around 100,000 miles and I recently ran into a problem with the car jolting, or slipping when I get on it hard. And also when I'm sitting at a stop light it will jerk forward like it wants to go. I've tried a few things like cv axels and some other things but I'm just hoping it's not the tranny.
View 9 RepliesI'm working on a 1999 Chevy Astro 4.3L with an occasional crank, no start condition. On any given day, this vehicle will start right up and run fine, although some days it will start right up and have a part-throttle stutter; not a dead miss, but a stutter when accelerating that sometimes goes away. When it has the stutter, disconnecting the MAP sensor will cause the stutter to go away completely. I replaced the MAP sensor, but nothing changed. Today, it's back to its crank, no start attitude problem. The basics check out fine: good, strong spark at the wires, 60-65 psi of fuel pressure, and I even pulled the plenum to verify fuel is firing from the injectors. Everything seems to be happening as it should except that it will not start and run. I even tried doing the Passlock relearn procedure on it, despite spark and fuel happening when it should, one or both of which would normally be eliminated by the security system, but to no avail. What could possibly cause this here-today-gone-tomorrow no-start condition?
View 5 RepliesI've noticed that when accelerating from a stop and turning onto an adjacent street to the left or right, there seems to be stuttering or shaking coming from the engine. I'm usually in ECO and only 1/3 of the way into the "engine half" zone on the HSI. It's not consistent but has become a bit of an annoyance.
View 19 RepliesI have a 2000 Corolla CE I bought recently that had 45K miles on it (it has a 4spd auto with O/D).
When accelerating from a stop, I usually take it very slow and I notice that there is a slight jerk most of the time.....it's sort of like I can feel the gears engage. This doesn't happen all the time and it doesn't seem to happen if I accelerate fast.
I did a transmission drain & fill with Royal Purple MaxATF (the drain & fill was only once).
1) Is this normal for this transmission? Also, is there a "pan drop" for this transmission? The mechanic only removed the drain bolt...he did not do the pan drop.
2) During my work commute, I'm in a lot of rush hour traffic where it moves for short distances at 5-10mph. It will shift from 1st to 2nd a lot of times...is better to just put the car in 1st (L) gear? My mechanic said no because it will heat up the transmission faster.
2003 F150 XLT 7700 4x4 5.4 Triton. While accelerating normally from a stop the transmission? shifts into 2nd with a heavy jerk. All other gears normal. It doesn't do this under hard acceleration or under very gentle and slow throttle application. Is this a COP issue, a transmission issue or just a driving style thing?
View 7 RepliesWhat can cause a car to jerk forward while accelerating? Other symptoms include loss of HP and MPG. Recently had spark plugs and wires changed. Regular maintenance. I am about to see my mechanic and ask him to check the fuel pressure.

Recently I've been noticing a gas smell after parking my car after the drive home from work, but engine performance and mileage efficiency didn't seem affected, and I found no visible evidence of leaking on the ground (nor in the engine, but I likely don't know the right places to look).
Today, with the engine running, I looked around the engine to see if I could locate any gas leakage -- I located the fuel pressure regulator (I think; a golf-ball sized acorn on the right of the engine with a hose coming in the top and a pipe coming out the bottom and going down and to the left) and didn't see any leaking during my brief test. I'll check it again after my drive home tonight.
One new thing I did discover, though; while in park, when I slowly pressed on the accelerator, there would be a point where the engine started losing power and going into a rev/slowdown cycle: about a second or two of revving, then a half second of slowing down. This was while cold and in park; I've not experienced this in normal driving.

Symptom, loss of horse power (from a stop and going uphill), surge or lunge forward when accelerating (misfire?), rough idle (occasional knock). Maintenance, regularly change all filters and fluids, recently had the m.a.f cleaned and changed air filter, spark plugs and wires, oil.
There have been times in the past year or so when the car would crank but not start. Especially when the car was hot. Wait a couple minutes and it would start. Also a couple of times the car would shake fairly hard when started, get up to speed and it was fine.
I have had people tell me anything from a clogged catalytic converter to bad fuel injectors or fuel pump.
Scanned the car last week. No codes showed up. Never had a Check Engine Light.
I forgot to mention that every once and a while the car will jerk when accelerating. I have a coworker who said his truck started to jerk forward and later would not start at all. Our mechanic said it was the fuel pump. I I will see what that does for him.
I have an '01 Impala, 3.8 engine with 200k miles. Whenever the engine idles, at a stop, or in a parking spot, the idle will drop, then the car will stall. It will start right back up, but unless you are actively pressing the accelerator, the same thing occurs. There's no sputtering or performance issues, and nothing to indicate that it's about to stall. I've replaced the IAC valve, AND the EGR valve. Still having the same issue.
View 5 RepliesI have a 2005 Impala with the 3.4 engine and 118,000 miles. About 2 years ago I had a code P0141 and since we didn't know for sure which oxygen sensor was out we replaced both of them. The P0141 code did not stop occurring after both sensors were changed. I read on an Impala forum that if you didn't replace the sensors with AC Delco the codes would continue so I didn't worry about it until my gas mileage starting going down recently. I ordered new AC Delco oxygen sensors and my husband replaced them Saturday, the old ones were sooted up pretty badly. Today a new code appeared, it is P0140, O2 sensor circuit no activity. What the problem might be now.
View 7 RepliesI purchased a 2011 Chevrolet Impala last year with 14,000. When the car reach 26,000 I begin to smell a very strong sulfur smell coming from the exhaust. I took the car to the local Chevrolet dealer and was told that the particles in the catalytic converter begin to break up at about 26,000 mile and the result is a sulfur smell.
I didn't believe that all Impalas had this problem. So I took it to the Chevrolet dealer in the next town where I personally know and trust the maintenance chief. He put his two best men on the car and could not find anything wrong. I was told to try another gas station which I did but it did not work. I now have 31,000 miles on the car and the smell is very strong coming into the passenger compartment when stopped.
I just bought a 2001 elantra. The car frequently will jerk or stutter while driving like the gas is bad or it is starved for something. When the stutter problem happens while driving the check engine light flashes but does not stay on. It usually only stutter 1 time but has as much as 3. The other day when I was in a drive thru waiting to order the car kinda sputtered during an idle then shut off the check engine light did not flash at this time. It restarted fine after that.
I pulled the codes and read them and I have 2. I am not sure if they are related to this problem. They were U0D00 and P0705. For the P0705 I cleaned the terminal but did not pull the negative on the battery the reset the computer. I reset the codes and the problem still is happening but no new codes are present. The code P0705 has not returned since.
While driving my 04 w12 a few months ago i noticed a "stutter" or brief jerk while driving. the next morning i had a "coolant level" warning. i took the car to a mechanic i use who diagnosed the problem as a broken coolant line involving the transmission cooler, with the result that coolant migrated to the atf. indication was that the tranny was toast, along with the atf cooler. I authorized a repair (not inexpensive), keeping costs down by installing a used tranny. since the car was "fixed" i still got a "jerk" usually in fourth gear, sometimes in third. i took the car back and was told that the tranny was flushed numerous times and the transmission was reflashed. i picked the car up yesterday, but i still get the "jerks", now usually in third gear.
View 3 RepliesAbout a week ago, my wife's Malibu (~130,000 mi) started exhibiting symptoms I would associate with a problem with the ignition system. It was idling rough, it felt like it was misfiring, and the check engine light started blinking when I was accelerating from stop up to 30-40 mph.
The timing was all weird because of the holiday, and so I didn't take it to get the engine codes pulled right away because I figured Id take care of it this week (we were traveling over the weekend).
My wife just called and said her car won't start at all. The car will try to turn over and she didn't describe anything consistent with a dead battery.
If I can't get it somewhere to get the codes pulled, what might be wrong? To summarize, it started idling roughly and maybe misfiring about a week ago, it sat for four or five days, and now it won't start.
I have a 2002 Pontiac Aztek with about 170,000 miles on it. About 3 weeks ago, it began having problems when I would hit the gas to speed up. It would hesitate, and then jerk forward and go. Then about 2 weeks ago, I was driving on the highway and the engine just suddenly stopped - as if I had turned off the key.
There was no warning, no sound, nothing. I kept hitting the gas the whole time and it started up again after a minute. I replaced the fuel filter and it ran well for a week. Then it happened again, but this time the engine completely turned off and I had to turn the key to restart the engine. The engine started with no problem.
I tried to drive to the mechanic, but the engine stopped & started again on the way, so I ended up having it towed. It is not driving roughly or idling roughly, it doesn't make any strange sounds and no warning lights come on. When the engine stops, all electrical components are still working (lights, radio, etc.). My mechanic appears to be stumped. What could be causing this?
I drive a 1999 Ford X V8, 189,000 miles and it's been a great car. Lately tho, and in particular when the temperature is above 90, it begins to miss, hesitate, then jerk forward all at once. Some times, when the accelerator is depressed, NOTHING happens. No response form engine at all. This can last three seconds of so, then the car will lurch forward. I have done a 180,000 mile complete tune up, a, fuel induction system service, replaced the Mass air flow sensor and checked all points, plugs, new air filter, etc. Still, the problem persists.
View 3 RepliesI have an 01 Buick Regal GS, 82k miles. When I baught the car it had 80k miles but had been sitting for a while. I put in a new battery and changed the oil as soon as I got it. When accelerating the RPMs will go up but the car won't accelerate as fast. The RPMs will drop and the car will jerk forward. And then accelerate better after it is warmed up a bit. I thought to give it some time and maybe it will go away. 2k miles later it is still doing it. What it could be?? I would like to see if I can fix it myself.
