I'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 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 2007 Ford Fusion 4.0L AWD. One day I went to pass a slower car and accelerated rapidly, but the car responded with loss of power and shook to a stop and would not re fire. I took it to the dealership and they said two cylinders were not firing and a fuse was blown. I looked on the internet and some people said their coils go bad or plug wires. I asked the dealership if that was the cause and they said absolutely not, but it's the ECM. They replaced the ECM and 2 days later my CEL came on and I took it back to the dealership and they told me my catalytic converter was bad and I could drive it until I had the money to replace it. Then a couple days go by and I was passing a tractor on the highway, I slowed down to 45 mph to make the pass and as I began to accelerated I felt a thunk, then about a mile later it started cutting out and shaking. This time it would re fire but idle rough. I tried on/off 3 or 4 times then it idled o.k. I then took it back to the dealership and this time they said it's all 6 coils.
View 7 RepliesI have read that when accelerating from a full stop, it is better to accelerate briskly, but keeping the bar graph in the ECO zone, to cruising speed is better overall for gas mileage compared to accelerating slower and taking more time to reach cruising speed....
I have also heard that it is better to accelerate using the bar graph and making sure it only goes half an inch past the ECO display above it. This way uses less RPM.
My 2010 Prius engine shakes/vibrates when the engine is showing between 50-75 MPG on the gauge/meter on the dashboard. There is no vibration when coasting (100 MPG on the gauge/meter on dashboard) or when I am accelerating pretty modestly. Only when accelerating very softly. It started a month or so after I had my spark plugs replaced at 133K miles last June 2015. It has gotten progressively worse. It is especially noticeable once the engine is warm or the outside temperature is warm. During the winter months the vibration was there slightly, but not nearly as noticeable as it is becoming now that warmer weather is here.
View 19 RepliesSlightly shaking engine and rattling noise on acceleration,it happens when the car is hot and especially when the battery level is very low ,I guess is when as more load . If I accelerate and keep it steady at 20mph I can feel a constant vibration but goes away once accelerating more....like if you're driving on a rippled surface ....that is only when engine is on , doesn't happen on electric only.
The noise it sound like a tapping coming from the engine when slowly accelerating from 0 that goes away as soon I give more gas ,is annoying wile in the traffic.? Can the sparks plugs be the problem?they been changed 120k ago.....,I cleaned the egv pipe but problem still there. Like I said is only when the engine is up to running temperature.
I bought a used Certified Prius with 49k miles on it. I noticed when accelerating (and the display shows that I am using the ICE but not so much that it shoots up into the "Power" portion on the far right) that the there is a clicking noise coming from the front passenger side of the car.
It sounds very much like this:
I don't hear it when only the electric motor is running, and I don't hear it when I really punch it and the power meter is completely filled up. Its more when the power meter is in the middle of the display and the ICE kicks in and I am slowly accelerating.
My 2010 Prius has been making an odd noise intermittently while accelerating. I haven't been able to reproduce it for the mechanics (of course). The best description I have for the noise is this. It sounds like the click/rattle sound a car makes when it is stalling. Just sped up. This can happen at any time I accelerate (even at highway speeds) but it usually happens just after I start moving from a stop. When it occurs it feels like there is a drop in engine power and I either have to take my foot off the accelerator, or push down harder and power through.
View 10 RepliesSo lately I've been hearing what sounds like a slight lifter knock that develops at 1500 rpm to 2700 (I have ultragauge) when accelerating or maintain speed, and it only appears when the engine is at operating temp and disappears when rpm is below 1500 rpm and above 2500 rpm my oil is running at 3900 miles using Toyota synt 0W-20 and it looks pretty clean and at high mark of the dip stick.
View 3 RepliesI have noticed in certain circumstances that the engine seems to be in a resonance where it is shaking noticeably and getting worse not better. It happens in two situations.
One is after gliding and slowing to make a turn (with the engine off). As I am exiting the turn and hit the gas the car shakes a lot for about a second or two, then smooths out.
I have noticed, in my 2012 Elantra with 32,000 miles on it, that my car is shaking at idle. I'll be at a red light or stop sign and the vibration is SUPER annoying. I have had it tested at a Hyundai Dealership. They couldn't "replicate the problem" and nothing it wrong with my car.
I may be trading this car in for the Veloster Turbo. I'm tired of how slow this car is. I know I sacrificed speed for gas mileage, but I have a question, does the Veloster have this problem as well?
2005 Prius, 135,000. At 20 MPH on acceleration engine stutters, solution?
View 3 RepliesI bought a second hand 2005 prius (gen II) at 125k km. Soon after I got the car I got p0402 and p0505. After clearing the errors, I got back only p0420.
About a month later, my car started randomly shaking both when accelerating and at idle. This happened 2 or 3 times in the span of 2 weeks. The CEL and traction control light started flashing. I stopped the car and started again like absolutely nothing happened 10 seconds ago. (This time I got only p0301.)
Yesterday, the situation with the shaking was horrible and I got p0301. Naturally, average fuel usage went up a lot. Even at idle on the parking lot, I turn on the aircon so the engine would start - the feeling is like the car is going to collapse any second.
I have recently used a new gas station, so I thought possibly bad fuel. However, if it was bad fuel, i should have gotten all misfire mistakes, right (p0300~p0304)?
So if I am getting only p0301, the problem should be either the spark plug, injection coil, fuel injector etc. for cylinder 1. My car is currently at the mechanic's place, so all of the above are being checked as we speak.
However, what I am worried about is that this shaking / lights flashing drama is happening at random. If it was any of the above, shouldn't is just happen all the time? When I went to the mechanic yesterday, I barely made it there. He was busy, I waited for 20 minutes, then he wanted me to drive the car for a bit to see the problem. This time the car was working like a brand new car. Absolutely nothing happened. He probably thought I was crazy.
So yeah, he will closely inspect spark plugs, injection coils, fuel injectors etc. If all of them are fine, where should we look next? Head gasket leak perhaps?
I've been noticing a clicking noise when the rx comes to a complete stop and accelerating from a stop. Sounds like a sticky caliper but just wondering if it could be some other suspension issue ... RX350 ...
View 6 RepliesSo it's an issue I've noticed 3 times now this summer. The car has been driven for at least 5 minutes each time and should be past the warm up phase. If I'm sitting at a light, the gas engine just keeps running. I thought it might be some kind of computer error so I tried powering the car off and turned it back on. EV mode will stay on for about 30 seconds but then the gas engine turns on again. Battery is 3/4 full like normal with the AC on. I've tried putting the car in EV mode but it says "not available". Temps in Houston have been in the high 90's recently so I'm wondering if this is the result of an overheated battery or if it's something I need to be worried about and take in to the dealership?
View 17 RepliesI have a 2004 F-150 5.4 Liter 4X4 supercrew with 6" lift and 35" tires. The truck has 123K miles on it. I am the second owner of the truck. In early fall the truck started making what I can only describe as a mild and inconsistent "stutter" upon accelerating between 40-50 MPH. It does not do it all of the time and really depends on the speed at which you accelerate. Sometimes it will happen between 50-55 MPH but primarily it is between 40-50. If you accelerate quickly though at that speed, it rarely ever happens.
Anyways, I changed the fuel filter (pretty sure it was the original as it was nasty and had chunks falling out of it), flushed the fuel injector system at a shop, gassed it up and treated the tank with fuel treatment, and removed the AIRRAID air filter, cleaned it out (blew out with air, flushed with water, dried and re-oiled it). The truck had A LOT more power behind it, my fuel mileage increased and for about a day, this stuttering did not occur. It has now started up again.
My question is whether or not this could be caused by old spark plugs or is it a transmission issue? The truck runs great otherwise. We've looked at the plugs and they appear to be the original plugs. I bought the truck with about 100K on it and have put the rest of the miles on myself. I'm trying to figure out if it is an issue with the plugs or if it is related to the automatic transmission as I'm sure the fluid hasn't been changed in it either. I know I'm going to have to do both but want to know what is more likely the issue at hand.
I have a 2010 F150 Xlt super crew with a 4.6L. I've noticed lately when I start from a full stop the the truck has a small shutter or hesitation before it starts accelerating. Its barely noticable but it is there. What it could be? I had the tourque converter replaced just before my warranty was up, I've only put 30000 Km on it since. Was wondering if it could be the cause.
View 3 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 have a 1997 Ford F-150 XLT 4.6L 4x4 Auto and it's having an issue. My truck has recently developed a stutter when accelerating. It feels like a serious misfire and actually pulled a code for a misfire on cylinder 7 (although I haven't been able to get the code to appear again). The plugs are pretty new, I think I only have around 10k miles on them so i figured it might be the coil pack. I bought 2 new coil packs but only one was in stock so i replaced it on the drivers side bank (which controls cylinder 7) and it didn't fix my problem. When I first start the truck and drive it, it isn't very noticeable, but as I drive the truck for a few minutes, the stutter gets more violent. I will replace the other coil pack tomorrow, but I have my doubts it's the problem. It acts just like a bad coil pack.
View 9 RepliesI've been driving a 2014 base model GX for a little over year now. I noticed that when the vehicle is in drive and is stopped at a stop sign/light on a steep incline (i.e. front of vehicle is at significantly higher than rear), when accelerating away from the stop, the traction control system (?) will beep and make some noise for a second or two if the car rolls backward from the stop when the brake is released.
