Ford F-150 (2009-2014) :: Vibration In Gas Pedal Happens Under Acceleration?
Every once in a while, I'll feel a vibration in the gas pedal. It happens under acceleration, and typically if I'm pushing down and it has not downshifted yet. Then once it downshifts the vibration is less noticeable.
I know there have been issues with the Electronic Throttle Control on these drive-by-wire trucks, particularly on the Super Duty trucks.
Pontiac - Grandam :: Gas Pedal Vibration During Acceleration Post Engine Work
The car is a 2000 Pontiac Grand Am, 3.4 L V6, 223K miles.
I had a major coolant leak and my normal repair shop couldn't handle it due to lack of equipment. So to a local dealership I went. The following is the assessment and work performed. "Cylinder head gasket leaking coolant. 12.80 Pressure tested coolant system and found the rear bank cylinder head gasket leaking coolant down the front of the engine. Replaced both head gaskets as well as intake, front engine cover gasket, valve cover gaskets and upper plenum gasket required for repair. Topped with coolant and performed LOF. Cleaned engine compartment area and road tested. Verified condition corrected".
When driving the car off the lot after the repair, I nearly stopped and went back in to complain. The gas pedal was vibrating on acceleration and its never done that before. I figured I'd drive it around for a while and see if it shook out and it didn't. I did drive back to the dealer the same day and rode with the mechanic who agreed that the vibration is there but didn't realize it was new. He went step by step through the repair with me. All work was done from the top of the engine down so the transmission and CV joints were never touched. The only idea the mechanic had was there is a small crack in the shielding on the throttle cable along with rust. I'm tempted to replace this anyways from a safety standpoint but could this cracked housing/rusted cable be causing the vibration? During the course of the repair, this is the only part that was touched that is related to the throttle. The throttle itself is fine.
The vibration only occurs when accelerating from a complete stop. It evens out once a speed over 40 mph is reached. It does not seem to be dependent on the AC compressor running.
Tiguan :: 2009 Transmission - Getting Vibration Upon Acceleration
So i have a 09 tiguan with 112000 kms. and lately i have been having problems with the transmission. i am getting a vibration upon acceleration and it acts up with its shifting like switching gears every once and a while like its hunting for a correct gear. this problem has been getting steadily worse. Is there anything i should know about these transmissions that is common to go on them that would cause this. the car is not beat on and i tried to get vw to do a filter and fluid change but they refused to stating it is a sealed unit and the do not touch it.
Is this a software issue (i highly doubt it) as i did a tb reset and it made it a bit better. i am at a loss with this car it is costing me a fortune. One last thing i had the prnd letters light up solid one time a while ago upon starting but it only did it once and never did it again. I am pretty sure this says there is a fault if i am not correct.
Ford F-150 (2009-2014) :: Vibration In Floor Board And Gas Pedal
I recently had a leveling kit installed on my 2014 f150 super crew 4wd. When I picked it up, I heard a humming in the front end that ended up being a bad iwe actuator. I took it to the ford dealer and they replaced it. No more humming, but now I have a very annoying vibration in my gas pedal that can also be felt in the floor board and gas pedal. I've had it aligned. I thought it might be my front driveshaft so I put it in neutral while driving and vibration is the same. It gets worse when I get up around 70mph. I also feel small jerks in the gas pedal at these speeds along with the vibration. It vibrates worse under heavy acceleration as well. Cause I can't wait to set my cruise every time I drive it bothers me that much. Only has 10,000 miles on it.

This vibration with sound on my brake pedal started after i change my stock intake to takeda. Well, Not all the time this thing happen, only when im in this kind of situation:
Pressing and hold my brake pedal at full stop and the gear is set to Drive, then, when the RPM goes down to below 900, the vibration with sound started, and it only disappear when i release my brake or when the RPM goes up automatically.
But, this only happened with this kind of situation when my car already heated up (like driving it more than 10 mins) and the temperature is at stable level.
While my car is just started driving, or its not already heated up, no vibration is happening.
Corolla / Matrix 2009-13 :: 2011 - Vibration On Brake Pedal While In Stop
2011 Corolla LE. Recently I upgraded the air intake, look at the picture
Shortly after that both me and my wife noticed that the brake pedal vibrates while car is In stop on lights. The vibration is only on the pedal and if you press it hard you suppress it. But when you feet is pressing light in the air it's very noticeable.
She also thinks that during above scenario RPMs go from about 1000k to 900 so are dropping. To be honest I did not notice that and not sure if this is normal or not. Other than that the car runs great and sounds much nicer bit loud but I like it.
Ford F-150 (2009-2014) :: Vibration In Gas Pedal / Floor / Steering Wheel
2009 FX4... Every once in a while, I'll feel a vibration in the gas pedal. It happens under acceleration, and typically if I'm pushing down and it has not downshifted yet. Then once it downshifts the vibration is less noticeable.
I have had the mechtronic unit replaced due to harsh shifting and the vibration was there before and after that was replaced. The drive shaft was also replaced due to a click/clinking noise and the vibration was there before and after as well. The harsh shifting and clinking noise was fixed with those repairs, but the vibration is still there. I notice it more when I am towing.
Avalon 2005-12 :: 2008 XLS Gas Pedal Vibration And Whole Car Shudders
My 2008 XLS has 172,000kms on it and has been having a vibration problem. Specifically, the gas pedal vibrates and the whole car shudders when it is between 55-80 km/h and in 6th gear. The shudder/vibration occurs when the car has to drop a gear to accelerate. After it downshifts, the vibration is gone. It has been happening for the past few months. The vibration did go away for a while after I changed the brakes. So, not sure what could be going on there!
View 1 RepliesFord F-150 (2004-2008) :: Slight Delay When Press Down The Pedal And Acceleration Actually Happens
I've been noticing over the past couple years that sometimes when I accelerate, there's a slight delay between the time I press my foot down on the pedal and when acceleration actually happens. From reading other threads it would seem that the most common fix is to re-flash the ECU. I bought a DiabloSport Predator tuner along with a CAI a while back to improve performance/gas mileage and I was wondering if there's a way I can use the tuner to re-flash.
If not, do most ford repair shops already carry these? I don't want to buy a flash programmer. Also, if the shop does carry this type of an item, what is the average cost to get it re-flashed?
I own an '04 F150 XLT 5.4l.
Ford - Explorer :: 2009 4x4 - Low Growl Hum Noise And Vibration Felt On Gas Pedal When Accelerating At About 40 MPH
I'm the original owner at 50k miles with Ford ESP warranty. Drive-train still under original warranty. I started noticing a low growl hum noise and vibration felt on gas pedal when accelerating at about 40 MPH. At first I thought it was the road or tires.
Then a few weeks later on a slight hill the growl-low hum was accompanied with a much more noticeable/louder growl/grinding noise in a heartbeat like rhythm. Took it to dealer and they first said it was the transmission. It was replaced.
Then they said the noise was from the rear differential/axle. It was rebuilt, oiled and sealed. Taking it back today for another drive with the mechanic to show them again the problem persist. What it may be? Also, my MPG has dropped significantly from an average of 18 to 13. This is while driving on 4x4 Auto.
Subaru - Acceleration - Noises :: 2009 - Forester Generating High Pitch Whistles When Gas Pedal Is Pressed
Right before Xmas our 09 Forester was hit while parked on the street. The whole front end of our car got wrecked. Was still driveable but we needed a new radiator, AC compressor, fenders, bumper, hood, lights, etc...over 5K worth of work.
As soon as we picked it up we noticed that when you press on the gas the car makes a high pitched whistling noise, almost like the noise when you'd try to tune in an old transistor radio. It only happens when the car is driving and the gas is pressed, not when parked or in neutral.
I know we should have probably brought it right back to the shop that day but I really did not like the shop at all and they are not at all convenient to where I live. I've read it could be a loose cat converter. I checked the air intake housing and that is secure.
Ford F-150 (2004-2008) :: Vibration On Acceleration That Seems To Come From Drive Shaft
2007 XLS Crew Cab 2wd. 60K miles When going through the 35 to 60 mile per hour range there is a vibration that seems to come from the drive shaft. Let off the gas and it goes away. After 60 mph it seems to be gone. I am thinking Trans support, motor support? One of the postings on this sight made me wonder about the transmission. By the way, I just bought this truck used and love it. Can I run flex fuel in the 4.6L engine?

View 6 RepliesHyundai - Elantra :: 2008 - Constant Sound And Mild Vibration On The Pedal
I have a 2008 elantra. It has 71600 miles on it. New brakes, & tires. 2 tires were changed year and 2 more the previous year. I have been hearing a constant sound and starting to feel a mild vibration on the pedal. First I went to a mechanic and he said I need to change the belts. Got that done, no respite. Next went to another, he said i probably need to get the wheel alignment done as the tires seem 'cupped' on the inside.
Went to the dealership, they looked at it said the same abt needing wheel alignment and asked me to change the timing belt!. Still same sound. Went to Sams club to look at the tires & they said check the brakes, tires are fine, it cannot wear out so soon and its not covered under warranty. Brakes got checked out as fine. Went back to Sams again and was told to check Suspension and Struts this time. Went to a mechanic and he gave me an all clear this morning! I am going on a road trip and don't want to be in an accident!
Ford F-150 (2004-2008) :: AFE Stage 2 - Loud Hum And Vibration When Step On Pedal
I just installed an AFE stage 2 on my 04 f150. I was driving down the freeway and I decided to step on it and it made a loud hum sound and it had a vibration I could feel through the pedal. It was so loud and aggressive I pulled off the road to see if something came apart. Everything looked ok and all my bolts and such are tight. Is this normal?

View 11 RepliesLexus IS 2014+ :: Buzzing / Vibration Feel From Gas Pedal?
2015 Lexus IS 350 AWD.
Any time I've been driving for 10-15 minutes, my foot starts to feel like pins and needles because of a buzzing/vibration feel from the gas pedal. If someone were to drive in stop and go traffic for 5 minutes, they wouldn't notice it. However, it takes me 30 minutes on a highway to get to work and my foot is on the gas pedal the entire time. However, within several minutes of having my foot on the pedal, I get this sensation as described above and it gets so annoying that I almost don't want to have my foot on the gas pedal any more.
I did change my tires when I first got my car with Michelin tires but kept the stock rims. I did this so I can save the run flat tires for when I return my vehicle after the lease is done. I highly doubt its from the tires as there are no vibrations or other feelings in the steering wheel or seat. The car is otherwise smooth.
However, I feel like there are these buzzing vibrations in the foot well of this vehicle. What it could be? I know these gas pedals are metal but I find it hard to believe that would be the reason.
Lexus RX 2010-15 :: 2011 RX350 - Slight Vibration In Gas Pedal
I have a 2011 RX350 and like car for the most part. Something strange I have noticed is that the gas pedal seams to have some little vibration when I am pressing it smoothly. My foot is constant on the gas pedal maybe 1/4 of the way down and it doesn't feel smooth like other vehicles. I have a 2014 lex IS250 and it doesn't have that vibration. Also had a 2004 RX330 and it did not have that vibration. It is a slight vibration that ruins the luxury driving experience.
View 4 RepliesFord F-150 (2004-2008) :: Engine Vibration / Miss At Idle - Slight Hesitation During Acceleration
I posted a while back about my 04 5.4 having an issue at idle. I did all the normal things like replace coil, spark plug, etc etc. No change to the issue. It still acts as though it's misfiring on a cylinder and I get codes P0306 and P0316. Finally took it to ford and had a diagnostic check ran. Everything on the top end was in working order. The tech even put a known working coil on 6 and nothing changed. I was told that it's either an intake or valve issue on that cylinder. But no definite answer to problem.
Fast forward to yesterday. I got a wild hair at lunch and went out and started truck. Pulled injector plug off of 6. No change to the way it was running. I did the same for 5, 7, 8, 1, and 2. All of which made a big difference in the way it ran. It was obviously misfiring with no fuel to cylinder. This gave me the idea to swap 5 and 6 when I got home to see if the issue followed the injector from 6. I did NOT. I pulled the plug on 5 and got the obvious change in the way it ran. So there is definitely something going on at cylinder 6 that I cannot figure out.
PCM, bad intake, bad valve? I'm not rich so a trip to ford for repair is gonna have to wait. Truck seems to run fine when driving except for slight hesitation during acceleration.
