I find it hard to smoothly accelerate from a stop with my V6 DSG. I have to be very careful how much pressure I apply to the gas to get a smooth take off...too easy to accelerate to fast or break the tires loose. Can this be reprogrammed?
View 3 RepliesHad brought this up before but it seems like the thread got black holed. After my car warms up, it feels quite a bit down on power and throttle response is a bit jerky. I just replaced the MAF and the coils hopping it would work, no codes on VAG Com. I was thinking maybe the green coolant temp sensor went out ? Car does backfire a bit when decelerating. Also the RPMs drop down a bit slower than normal lately.
Cam sensors are not loose.

I have a 1997 Honda Cr-V. Everything is great except, when I try to accelerate. From a stop, say, at a light, I cannot get it to accelerate smoothly. It feels like the engine gets bogged down. I almost have to feather the gas peddle just to get it to go. Once its gotten going and I am accelerating over about 15 or 20 mph everything it fine.
Also, when I've reached my intended speed and let go of the gas peddle, only to accelerate again, there is no problem.
My wife got a 2014 Tiguan (R-Line) yesterday. Nice car but throttle response is slow.
Wondered to know about APR Stage 1 tune on a Tiguan.
Title says it all come to a stop, step on throttle nothing, let off and step on it again it goes, does some one have to be killed before Ford knows there's a problem, it's happened to me 3 or 4 times in the last month, dealer checked said there's no codes so nothing wrong. OK I forgot the good info 2014 eco screw 4X4.
View 12 RepliesResetting Throttle Response. I came across this video, bored and just playing around, and tried it on my 2013.......and it works! Turn the ignition key to the run position, then slowly press the accelerator pedal to the floor. Then let the pedal up fast, then turn the ignition off. Do this 3 times, and on the last time, also turn the ignition off. I was amazed that that the lagging pedal response was almost completely gone!
View 4 RepliesExperiencing sluggish throttle response on the EFI Ecoboost? I have had several incidents where I'm needing to change lanes fast and the response is a dead second or two before the motor catches up to the throttle position. Then, it rockets forward at full throttle to catch up. By that time it's too late to change lanes and I have to be on the brakes hard to keep from rear ending the guy in front of me. I'm coming from a carburetored Toyota Tacoma that was far more responsive (minus the power) then this truck. I never felt hesitant to jump on it and go. Now I feel like my life depends on waiting until I have all day to change lanes, make a left turn or pass a slow moving vehicle on a two lane road. Is this something the dealer can adjust?
View 14 RepliesEco/Normal/Sport S/S+ Mode... the literature doesnt say much except it changes throttle response and power output. For the Sport modes it says that "The rear-wheel drive IS 350 F SPORT's Sport S+ mode also tightens the suspension..." Are the shocks somehow adjustable, or is this just marketing BS?
View 14 RepliesI want to get rid the delayed throttle response on my 01 B5.5 passat V6. I've heard of this "Sprint Booster" product, which seems like it works, although it kills your throttle modulation abilities. I was looking into the Unitronic chip, its supposedly gives 16HP .
View 21 RepliesFeel that VW has tuned down the throttle response of 2.5 I5. Well after having the car 2 weeks now, I don't hate the engine as much, and I don't think the issue I am having is with the engine it-self. In sport mode and tip mode it is much better, Once the car decides to give me what I want, it has plenty power. But in auto mode, It has to do with starting off from first gear at a stop. I really believe it has to be a software problem the way the throttle is mapped in the DBW. The problem is there is little throttle response off the line. Like I push the accelerator down halfway quickly, and the engine throttle opens maybe 1/8 and slowly goes to 1/2 like 5 seconds later. It's more of a drive-ability problem. It's like no other car i have ever driven. If I give half throttle, I expect the car to open to half throttle immediately, and not delay it. I really hope VW comes up with a fix for this, I'm sure it is just a programing problem. So am I the only one?
View 3 RepliesWhen the engine is cold, and up to about half way to 190 degrees on the temp gauge, the throttle seems to not want to open very far. Almost like there is a disconnect between your foot and the throttle. You get a little acceleration but no where as much as when the engine has warmed up. I have noticed this when the outside air temp is below 25 f or so. Is this some goofy emissions or "save the motor until its warm" thing?
View 12 RepliesI own a 2004 Passat- 1.8. I want to make my steering and throttle more responsive. The throttle is very slow responding, and the steering is very sloppy. I know this is supposed to be VW's Luxury car, but this would greatly enhance the performance and driveability of this car. How do I do this?
View 5 RepliesI purchased a 2014 3.6 SEL from a non VW dealer. They may have put regular gas in the car, I feel like it runs weird, feel a delayed throttle response and a little stutter before acceleration? or is it just me?
View 6 RepliesI am curious to see what you think. I had my car chipped by upsolute. For as long as I have had it and even when I took the chipping off, restoring my car to stock, i was getting pressure spikes, lousy throttle response and lousy gas mileage. For a while, I was going to the dealer every other week or so, trying to find out why my car was kicking into limp mode. Upsolute said it was the car and the dealership said it was the chipping.
Anyway last saturday I was inspecting my air filter and airbox (nice little pile of sand and a couple of leaves in there-I am sure that didn't work my mileage any). I moved the airbox a little and the hose which connects to the airbox underneath the air intake ductwork, fell off the airbox on its own. It was never clamped in place. I am told that is the hose that goes directly to the MAF Sensor.
My question, if all else is tight, do you think I have found the source of my over pressure and lousy gas mileage problems? The car certainly feels like it. I went and tightened up every hose connection I could find. My car feels like it has a new motor with a healthy growl to boot. Mileage appears to be up as well. What do you think? I thought about restoring my chipping but I wont do that.
One is that I have a very good extended warranty still in effect and don't want to risk losing it. They would love to hear the car is chipped. Then its good by policy. The other reason is that the guy who chipped it said he would put it back in but would not remove it if I am wrong. The dealership said they could not and would not restore my car to stock even though I cannot believe they don't have the tools around to do so.
So after owning my R for just over a week I've noticed that when I accelerate hard or let off the throttle the shifter seems to move quite a bit. Is this normal with the stock mounts or is it something I should have looked at? I know the stock mounts are rubber to aid in isolating the vibration of the engine but it seems like the shifter moves a little more than I would expect.
View 1 RepliesI took my car in for the 10,000 mile service on friday. The tech noted that there is an active TSB for the 1.8 TSI engine that addresses an issue with the turbo engaging just before the shift from first to second gear resulting in a non-progressive throttle response. I told him that I didn't seem to really notice that issue, but to go ahead an install the software update anyway. He did. I'm surprised at the difference. The throttle is much more progressive and I feel like I have better control of the throttle. I highly recommend this update. This may also explain why the 2015 Passats with the same engine have a higher MPG rating than the 2014s. If this update prevents the turbo from coming on unnecessarily then that would certainly save on gas.
View 21 Replies2010 Prius. There may be times when you attempt to accelerate from a stop on snow or ice where the throttle will not respond. The reason for this is that our hybrid vehicles have 100% of the electric engine's torque available at 0-1,500 RPM unlike our gas-only vehicles, where maximum torque is available around 4,000 rpm. If the Traction Control System detects wheel spin it will inhibit the throttle because if the tires were to spin and then suddenly gain traction, the torque would be so great that damage could occur to the transaxle.
View 19 RepliesI just have a 1999 ES300 that is having a strange issue. I realize this is a toyota forum, but the engines should all be the same.
When you accelerate from a stop at full throttle, the car feels very sluggish moving up the RPM range, and acts as though it is missing and stumbling the entire way up. If you do the same acceleration at lets say 70-80% throttle its much faster and much smoother (like the car is supposed to be). Works just fine until the car hits like 55mph, then power just cuts out.
If I'm revving the car in park or neutral its the same story. Works well at part throttle, but full throttle it misses as its revving up. To me this seems like 100% some kind of weird electrical issue. I'm having a tough time tracking it down though.
Things I have done:
1. At one point i had an VVTi OCV code for the rear bank, so I've replaced both OCV filters, and removed tested and replaced the RH OCV valve (they were both working to spec, but the rear one had a little more play in it).
2. No codes by OBDii scanning.
3. Cleaned MAF
4. Checked intake hoses for rips (there are none)
5. TPS seems to be working well based on OBDii diagnostics.
So of course the dealership isn't going to diagnose this since "the car's not supposed to be driven that way" - but I get a nasty rumbling noise when I accelerate from a dead stop with wide open throttle. It only lasts for the first few thousand RPMs in first gear, and after that it is gone.
I was guessing that it might be the transfer case or something like that, but it's really hard to tell. I do have AWD. I did not have any such problem in my previous GS, which was a 2007 (current is a 2010). It's worse when I accelerate around a corner, and it also makes a small noise when I'm going above 80ish mph, which of course the dealership isn't going to diagnose either.
A couple months ago i posted that i had some choppy acceleration. I didn't do anything about it because I was looking for my vag-com cable but couldn't find it. well, i still haven't found it but my problem is getting worse. I have an older version of vag-com 303 and i think that it only supports serial.
Let me also describe my problem and what i have done so far to try and remedy it: basically, when i start to accel from a stop it doesn't accel smooth and feels like it is about to go limp and then all of a sudden i get this burst of accel. it is much more noticeable when accel from a stop but it is also noticeable when pressing the throttle, just does not accel smooth and once in a while, i get this sudden burst of power. And the car has gone into some kind of limp mode twice so far.
Once with my wife and just the other day when i was on the freeway, i lost all power and the EPC light came on and the ESP round arrow thingy. i pulled over, shut off the car and 30 sec later i was able to start driving again and all the lights went out, but of course, choppy accel still persists. the other day when i was accel i heard a POW from underneath. and my wife tells me she has heard it once before. when i remove the cable from the MAF everything goes back to normal. i cleaned the existing MAF, and when that did not work i replaced the MAF and still the same problem.
It seems like the first thing in the morning when I pull out of the driveway my car acts like it not accelerating smoothly. It's kinda jerky and seems like it takes a second to get the gas. I mean I know some cars are a little jerky after not being driven for a day or so but she is brand new, only a few months old.
