Prius (2004-09) :: Gas Pedal Too Hard For Acceleration After Spark Plug Change
I have a 2007 Prius with ~180000, which runs great. The mechanic shop I used for oil change suggest me to change spark plug because they are dirty. After the change, I found I cannot step on the gas pedal too hard for acceleration. The car will hesitate, choking or die if I try to accelerate too fast. But if I step on the gas pedal gently, and let it reach the desired speed in a slower way, it has no issue. I went back to the shop and they replaced with another set of 4 plugs, and no improvement. I checked air intake tube and it looks no leak, but really old. Other than that, the car runs great.

Got stuck in the sand pits today. While trying to get out by going forward and back. I always get the front end starts bouncing hard. I always let off. Is this wheel hop or axle wrap?
Whatever it's called. How do I minimize this. It's a shame to have all that power and not be able to lay it down.

Golf/GTI VI :: 2010 - Heavy And Sluggish In D Mode When Going From Full Stop To Acceleration
Just this past weekend my wife got her 2010 Golf Highline with the 6-speed tiptronic transmission. Just a quick question about the gas pedal. when it is on "D" it really feels heavy and sluggish when going from full stop to acceleration. the pedal feels so hard and when you step on it feels like its not going at all. but as soon as it goes on 3rd everything seems ok. and then we tried putting it into "S" (sports) mode and everything was really good and quick. but when on this mode you need to be really hard on the gas pedal for it to run smooth. so i guess my question is...is it really like that when driving in the "D" mode??

I bought a 2001 chevy malibu about a month and a half ago.when I test drove it,didnt notice any problems or leaks...after driving it for a 2 weeks...the brake pedal would drop to the floor while driving and then if I hit it again real quick it would be ok...this problem would happen now and then....we replaced the right front caliper thinking that it was sticking and bled all the brakes..There was air in the system..everything was fine for about two more weeks then while driving the pedal would get hard when applied and then drop again..not all the way to the floor,and it alternates that way..what are your thoughts? I don't have much money to fix this problem.

I've got a 2001 Excursion with the 7.3 and while out driving around on Friday I noticed that my brakes were gone and when I pushed the pedal it went straight to the floor. I pulled over and put in brake fluid (it was empty) and managed to get home. I have discovered that the brake line (it is metal) that runs from the front to the back is rusted out and the brake fluid is just pouring out of it. What is the part called? I spent about a half hour looking for that particular schematic on the ford parts web site but couldn't find any mention of that brake line. Here is a picture. There are 3 metal lines and one is leaking the brake fluid? Can I fix it in my driveway or should I have it towed somewhere?
View 4 RepliesElantra MD (2010-15) :: Road Vibrations In Pedal / Floor
Is it normal to experience road vibrations in the pedal and floor? I've owned my car for about a month now (it's a used 2011) and it has brand new tires on it, but the past week or two it seems these road vibrations have worsened.. it's like I can feel the texture of the road on my feet. If I reach a freshly paved area it goes away like magic.
Is this indicative of a problem that I could have the dealer investigate? Or is this a "characteristic" of this car? I came from a 97 Corolla, with the exact same tires on it, and it did not have this problem at all. Then again, it was also much much quieter going over bumps too...

My 20th Ann. Is jerking under acceleration. When I hit the gas pedal slightly hard it starts jerking. Every once in a while the CEL will flash on and off. I changed the spark plugs and coil packs, cleaned the MAF, and now I have no real direction where to go. Maybe it could be a vaccum problem...

View 19 RepliesPrius C :: Pedal Went All The Way To The Floor On Sudden Brake
2013 Prius c Two, bought brand new with 15 miles on it 5 weeks ago. A few times when driving, I noticed the brakes seemed weak, like they weren't stopping the car very well even at low speeds (My driving is mostly in town on residential streets, so I'm rarely going over 35 MPH. Even so, I'd have to really mash the pedal all the way to the floor to get the car to come to a complete stop, otherwise it would keep moving forward. Several times I ended up about 5-10 feet past the line, sticking the front bumper into cross traffic. Luckily no one hit me. I chalked it up to the quirks of a different car than the one I was used to, and figured if it kept happening I'd take it to the dealership.
On Monday, my wife was stopped at a red light. The light turned green and the car in front of her started to move forward. After a few hundred feet, he suddenly slammed on his brakes. She said her brake pedal went all the way to the floor, and the Prius didn't slow down at all. She hit him going about 25-30 MPH and totaled the Prius. She's an excellent driver and I've been with her before when she's had to panic-stop. She's never driven a car without ABS, so she is used to pushing the pedal hard and keeping her foot on it. She wouldn't even know how to "pump" the pedal. She swears the pedal just went all the way to the floor and the car didn't slow down at all.
Prius (2004-09) :: Brake Pedal Went To The Floor And Car Wouldn't Stop
I was going down the highway at 70mph and came up to a toll booth when the brake pedal went to the floor and the car wouldn't stop. I hit the pedal hard and the car stopped in a very jerky manner as if the abs was initiated. I looked at the dash and the ABS, (!), and brake lights were illuminated. I turned the car off and then on again and the lights were off and the brakes worked normally again.
The Toyota dealer in CT said the weak battery was causing an under-voltage at the stroke sensor and replaced the battery. They told me if I lost my brakes again (!) I should bring it back for a new stroke sensor. In hindsight, I should have just told them to go ahead and replace the sensor. Two days later, driving down Florida route 301 in the rain, a stoplight went from yellow to red in about 3 seconds so I hit the pedal hard. The back brakes immediately locked up, the front wheels kept rolling, the car swerved and slid through the red light intersection sideways.
I counter steered and slid between two cars at the other red light, on the wrong side of the road as I straightened out. The car swerved and slid sideways again in the other direction and then spun around so I finally wound up in the correct lane, and I drove off like nothing happened. I was doing maybe 35-40 at the time and it's a miracle no one got hurt. Again I look down and see the lights illuminated. I cycled the power switch as before, and again the problem went away.
About an hour later the problem came back and this time no amount of power cycling will clear it. Basically what I'm understanding now is that it's the regenerative side that doesn't work with the bad sensor. The hydraulics kick in at around the last 10% of the pedal so the car will still stop, but I have to floor the pedal and that makes the car think your trying to lock up the wheels so it initiates the ABS system which makes stopping jerky and unpredictable. BEWARE the stoke sensor!!! What a dangerous design!! The dealer has the car now...
Diesel - Ford - F250 :: Hard To Press Brake Pedal While Driving
My truck is experiencing a hard to press brake pedal. It comes and goes and does not seem to happen at any one time while driving. I know that my truck uses a vacuum pump and instantly replaced this as I figured that with the age of the truck it should be done. However even with a new vacuum pump it did nothing to correct my problem with a hard to press brake pedal. I inspected all the lines to ensure that they are holding pressure and replaced two of the three with new lines. Again it still did nothing to correct the issue. I do not have any leakage coming from the master cylinder and no hiding noise from the brake booster.

Elantra MD (2010-15) :: Loss Of Acceleration Suddenly While Still Pressing On Gas Pedal
My Hyundai Avante (2011 model 1.6) suddenly loses acceleration while my foot is still pressing on the gas pedal. Every time that happens I have to raise my foot from the gas pedal and press it again to make the car accelerate. This thing happens randomly, but mostly at speed lower than 80 Km/h
I tested the car on an empty road once; I didn't raise my foot from the gas pedal this time when the car lost acceleration. The car speed dropped to zero and the RPM gauge returned to idle (i.e. around 1000 RPM).
The check engine never light up during or even after this thing occurs. Here is the list of things the mechanic tried on my car:
1-Cleaned the body throttle
2- Tested the car with another used body throttle
2- Tested the car with another used gas pedal
3-Check the fuel pressure and injection
4- Checked the sparks
5- Tested the car onboard computer.
None of the above worked!!! Here is the strange thing my mechanic discovered, if he unplugs the cable of the Anti-lock braking system in the car. The problem never occurs.
I have been driving the car for two weeks, with the ABS system unplugged. The loss of acceleration problem never happens. I am not sure what the ABS has got to do with the car acceleration.
