Lexus GX 2004-09 :: 2005 GX470 Shaking While Driving When Accelerating Above 20 - 25 MPH

I have a 2005 GX470 with about 50K miles. Over the last few weeks it started exhibiting a weird problem. When accelerating above 20-25 MPH it starts shaking. Not the steering wheel. The entire car is shaking as if driving over rocks. It is pretty annoying, and I am now concerned as it seems to have gotten somewhat worse than before.

Tires are rebalanced and rotated, so i dont thing it is that. My wife is freaking out, as she is driving it with 2 small kids.

Kia - Sedona :: 2004 - Front Wheels Are Slightly Out Of Balance When Accelerating

109K and runs great except for when accelerating from start to any speed. The front end acts likes the front wheels are slightly out of balance. Once you stop accelerating all is fine. Tires have plenty of tread and no I haven't rotated them to the rear which I might do?

Kia - Sedona :: 2005 - Overheating / Leaky Head Gasket Or Air Pocket?

I've been having trouble with the cooling system of my 2005 Kia Sedona (about 90,000 miles) and a couple months back I had the system flushed, coolant added and thermostat replace. Not long after this the overheating started up again. After the first five minutes of driving, the thermostat starts creeping up above the half way mark and within about ten minutes it hits the H. My vents also don't blow heat. After ten minutes the heat SOMETIMES suddenly kicks in after the needle hits H, but it's kind of inconsistent and sometimes I get no heat even after hitting H and sometimes I get a little heat and then it goes away. I only drive it 15 minutes each way so am not sure what would happen if I kept driving.

Anyway, I took it back to the shop and they did a pressure test and said they thought it was a leaky head gasket and that they couldn't do the repair and I should take it to a Kia dealer. I picked it up and on my way home I noticed I was getting heat from the vents immediately and the thermostat stayed at the halfway mark. No overheating. Is it possible they are wrong and the pressure test knocked some air out of the system and that the test actually fixed the problem? Can a pressure test give a false result?

Golf IV R32 :: Shaking While Accelerating Above 50 Mph

I just bought my first R32 a few weeks ago, 100% stock and spotless with 75k miles on it, after about a week, the car started shaking when coasting (immediately after removing foot from the accelerator) around and above 50 mph. When it first started it was pulling to the left and shaking in the wheel, i went and had an alignment done and it seemed to only dull the shaking, the tires were alittle worn so i went and got all new tires and it has taken the shaking and pull completely out of the steering wheel, now only the car itself shakes, not while accelerating, only when i take my foot off the accelerator. I've been told everything from motor mounts to spark plugs

Toyota :: Shaking While Accelerating Especially Within Range Of 45-75 Miles Per Hour

I have a question regarding my shaking car (Toyota Avensis Diesel 2.0 1999) while accelerating.

The shaking occurs when I accelerate, especially within the range of 45-75 miles per hour (70-120km/h). It's at it's worst around 60 mph. Whenever I release the gas pedal it stops. It also stops whenever I go faster than 75 mph. When I drive at a constant speed between 45-75 mph, the car stills shakes, but a bit less than when I accelerate. It doesn't seem like there is any specific location from where the shaking originates. It's all over, but there's no shaking of the steering wheel itself. The tyres are ok. After some suggestions I recently put some injection cleaner into a full tank, but with no results.

Honda - Accord :: Shaking Beginning At 55mph When Accelerating

I recently purchased 4 brand new michelin tires. They are approximately 3 months old now. Beginning a couple weeks ago, my car started shaking profusely at 60mph when accelerating. When I let off the gas, it would stop. I went and got a tire balance thinking that was the problem... but it's still happening, and now it starts at about 55mph. I have no clicking sounds when turning the wheel, and my car runs great besides this! What this could be?

Prius (2010-12) :: Stutter Or Shaking From Engine When Accelerating From A Stop

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.

Accent MC (2006-11) :: Front End Shaking While Accelerating At Lower Speeds

My 2007 Hyundai Accent gs shakes really bad while I am accelerating at lower speeds. I thought the front driver's side tire was loose or possibly had an air bubble, but could find no evidence of such. The rim and the tie rod looks fine, but it is shaking bad. It pretty much stops shaking when i reach higher speeds (60+mph), but when I am stopped and need to accelerate or turn it gets frightening.

Toyota - Camry - Vibration - Corolla :: Shaking When Driving Especially Around 35 - 45 Mph On Accelerating

Two cars, a Toyota Camry and a Corolla, are shaking when driving them, esp. around 35-45 mph when accelerating. This started right after a historic snow storm in Virginia that brought 24" of snow and temperatures in the teens and a bit lower. Nothing appears to be wrong with any of the tires. The shaking feels like the car as a whole; it does not really come through the steering wheel. We`ve only driven each car once since the storm.

I`m thinking this may be from all the moisture and cold. Does this sound reasonable? Do you think it might work its way out, or do we have serious problems with two different cars on our hands?

Ford F-150 (2004-2008) :: 2006 5.4L - Shaking When Slightly Accelerating

Ok, I have a 2006 Ford f-150 5.4L engine. it has 88000 miles on it. Here recently it has started acting up on me. It starts shaking violently when I slightly accelerate going up hills at any speed. On level ground it doesn't do it. Going down hill it doesn't do it. When stopped it doesn't idle rough.

It does this shaking when I barely press the gas. When it starts I either let off the gas or I push the gas to the floor and it stops. What is going on? This is the first Ford I have ever known. I don't know anything about these vehicles. I have read it might be the coils and plugs but then people have told me it might be the torque converter.

Ford :: 2007 - While Accelerating Loss Power And Shaking At Stop - Won't Fire Again?

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.

Ford Super Duty (1999-2016) :: Shaking When Accelerating Or Braking From About 40 - 60 MPH

Truck is a stock 2001 f250 7.3 with 205,000 miles. When accelerating or braking from about 40-60mph it starts to shake a little bit. When braking it shakes a lot more from 60 down to 40. But the faster you speed up the less it shakes when taking off. Looked at everything underneath is tight, and it has stock a stock steering stabilizer. Would a new stabilizer fix this you think?

Prius (2004-09) :: Gen II Car Started Randomly Shaking Both When Accelerating And At Idle / Code P0301

I 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?

Ford - F150 :: 2005 - Shaking When AC Is On?

I have a 2005 f150, when my AC is on (it's summer in the south so yes it's on constantly) my truck shakes. The best way to describe it: you know when you're at an idle, and the vehicle wants to stall out and it has that shake to it? That's what my truck does when the AC is on, I mostly feel it when there is no gas applied. Also my AC makes a horrid sound when idling (like a loud pop now and then) and unless I'm driving, it won't blow cool air.Why?! Simple fix or time for a new AC?
