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.
Saturn - Hesitation :: 2003 L300 Slightly Kicks When Pressing Gas Pedal At Low Speed
I have an occasional issue when pressing the gas pedal while stopped or at low speed the car hesitates and slightly kicks. It doesn't seem to happen at high speeds. The auto mechanic I took it to said he is getting a read that it might be the thermostat. My temperature gauge has not moved above normal. The auto guy says they need to start with the thermostat and see where we are with the problem at hand afterward. This does not make sense to me. Maybe the electronic read is right and the thermostat needs replacing, but how can this affect my occasional hesitation problem?

2001 F150 V8 4.6 Liter... I've been experiencing hesitation when first pressing the gas, stall at idle, RPM fluctuating between 1000 and 500 at idle and loss of acceleration. Had the truck read at autopart store and received a P0402 error and misfire is cylinder 8.
At this point, I've changed the the plug, COP, EGR valve, EGR Valve Solenoid and DPFE sensor and still have the exact same symptoms. I've also changed the plug for cylinders 5,6 & 7 as well. The check engine light is on, went off briefly after changing DPFE sensor, but back within a day.
Given the fact the error code is P0402 and some of the threads I've read, I thought the issue was centered around the EGR system, but I've replaced many of the components.
Elantra XD (2001-06) :: On Pressing Pedal RPMs Jump But Car Does Not Accelerate When In Motion
I have manual shift and the clutch is worn out. when in motion if I press the pedal the rpms jump but the car does not accelerate. only way to accelerate is to press very gently.
Q: do I always need to change the flywheel, which is expensive or changing just the clutch will do??
Ford Brakes/Suspension :: After Pressing Pedal Resistance Became Really Soft And Brakes Very Sensitive
I have a 2004 Ford Expedition and today on the freeway I had to step on the brakes pretty hard to avoid an accident. After pressing, the pedal resistance became really soft and the brakes worked, but were very sensitive (a lot of pedal movement to brake). I had this happen some time ago and I did a complete system flush and no problems since then, but it has to do with how hard I hit the brakes. What could be wrong????? BTW - I never noticed the anti-lock brake pedal pulse at all during this event. I'm not even sure it is working at this point. No dash lights to indicate an error of any sort.

I have a 2001 Elantra with 126k miles. For months it's been randomly hesitating, meaning I'll be riding along and suddenly the gas pedal will do nothing...then about 3 seconds later, VROOOM, the gas pedal will start working again. Recently, it's started stalling as well.
I've already replaced the MAP sensor, input speed sensor, throttle position sensor, spark plugs, wires, and coil pack. Nothing has worked, but it is getting progressively worse (it stalls more frequently, and the gas pedal becomes suddenly unresponsive more often).
GTI 337/20th Anniversary :: 2003 - Zero Resistance When Clutch Pedal Pushed
My clutch has been feeling very strange lately, and has had a mind of its own. I have looked underneath myself, and have even taken it in to two transmission speacialists and they can't figure it out. The master cylinder isn't leaking, and the slave cylinder is fine as well.
Here's what is going on with my clutch...
- I will push in the pedal, and there will be ZERO resistance until about 1 inch from hitting the floor, then all the pressure is there, and I am able to shift. However, sometimes I won't even be able to put it into gear because the clutch won't engage.
- Then I will pump the pedal, and slowly I will gain a little more room on the draw of the clutch, and it will feel fine. All the way to the point where a few days later it will be driving like new.
- Then it will start feeling funky again a few days later and the cycle starts over.
I drive a 2003 GTI 20th AE.
Golf IV / Jetta IV :: 2003 - Clutch Pedal Went Straight To The Floor With No Resistance?
So last evening, I went to start my car and the clutch pedal went straight to the floor with no resistance. Car started and was extremely hard to get into every gear. Felt like the only thing pushing the clutch pedal back up was the spring underneath the pedal itself. Clutch pedal was 100% just the day before. Got the clutch line bled (vacuum bleeder) and it worked fine again.
Any clue as to what could caused this overnight?
Its a AWP 1.8t jetta with ASR.. I believe I came across something about a revision in the hydraulic line but I'm not sure.
Golf/GTI VII :: Hesitation / Acceleration Delay When Push The Gas Pedal
I am a first time owner of a 2015 VW Golf TSI and TDI, previously drove an Acura RSX.
I am noticing on both cars, more so in the TSI, that off a dead stop, when I push the gas pedal there is a hesitation/acceleration delay that I am not used to.
Is this normal? I just want to make sure that nothing is wrong with my cars as I am not well versed in this stuff.
Also, if it is normal, what is the cause behind this? and can it be modified to remove this lag?
Ford 7.3L Power Stroke (1999-2003) :: Resistance Of Accelerator Pedal At Around 1000 RPMs
If I could determine the resistance of the accelerator pedal at around 1000 rpms, couldn't I rig up that resistance and switch it on in the accelerator pedal circuit to make the truck go to high idle? Any flaws in my thinking?

When I so this its like pressing in the clutch and revving it but my car is an automatic. During the upshift and downshift there is no jerking or hard shifting so I would assume this is OK? And is full throttling your car every few days bad or good?

It's a 2003 Mountaineer with a mechanical throttle not drive by wire. For about two weeks while idling in park or in gear but stopped in the drive-thru, the engine revs upwards of 1200-2100 rpm. Runs fine normally, no check engine light, no misfire and doesn't matter if the A/C is on or not.

My car is misfiring, as in acceleration 90% sputters until I lay the pedal to the ground, which obviously isn't good for my gas. What do I do? I can't find anything online and I don't want to be throwing money into things that don't work.
View 4 RepliesElantra GD (2013+) :: Wavy Acceleration Feel And Hesitation
My car has the wavy acceleration feel and sometimes hesitates a bit. It is way worse when the a/c is on. I wonder if this is a octane or spark plug issue. On my old cruze 1.4t the gap was wrong from the factory. It came with all four gaped under .022 but the manual called for .028. Everyone gaped to .035 with great results. Checking the spark plugs?

I have 03 f250 v10. just replaced the engine and got everything all connected and started it up and it idles great...the problem is that when you press the gas pedal it starts to drive but then it looses power and acts like its missing. cant get it to go 30 mph. While keeping it floored eventually it gets up to 2000 rpm and then starts to pick up speed.

It'll do okay when I am not flooring it, but when I do floor it there's a pretty noticeable lag and then VROM it'll take off like a bullet... This car has a manually operated throttle control, are there any adjustments I can make to make the truck more responsive? 2.4L 4Cyl....

View 1 RepliesSanta FE SM (2001-06) :: Slight Hesitation During Acceleration Suddenly
Last night i noticed a slight hesitation during acceleration. Today i had driven around in town for awhile and did not notice any hesitation. When i got onto the interstate I pushed down the peddle to pass someone and it did nothing, I let off the gas and back on and the car bucked pretty bad. All the way home it has issues when I pressed on the gas but did fine at cruising speed. I would think a fuel filter would have been a slow progression issue so I am thinking maybe it is a sensor. I sprayed carb cleaner around vacuum hoses today and did not notice any surge so I think I eliminated a vacuum issue.
