Passat (B7) :: Odd Throttle Response When Cold - Little Acceleration
Nov 25, 2014
When 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?

I 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?

Is it possible bad spark plugs and wires affect poor acceleration and bad throttle response.I have no error codes and the engine is rebuilded.Idling sound good.Difficult to start engine first time(seconds after-easy to run the engine).
Tyre size 195/65/15 winter?

My 2007 Chevy Impala with the 6-cyl engine is, overall, a nice car. One thing I just do not like about it, though, is the electronic throttle. There is a quite annoying lag between acceleration on the gas pedal and response from the car It isn't just my car, all the Impalas and other cars I test drove when shopping for the car are the same way. Even the 2007 Buick with the last year of the 3.8 L engine had a touch of lag time compared to the 1987 Olds Cierra I had with its 3.8 L engine and mechanical throttle. I'm no lead foot but when I want acceleration I want it now and not later. Guess I got spoiled from 20 years driving the '87 with its giddy up and go.
When making left turns without a traffic light, I have to allow a much wider open slot in oncoming traffic than I ever did since driving the 1973 Toyota Corolla with its four weak hamsters under the hood. I'm not the only person I've heard gripe about electronic throttle. I have to wonder what about drive by wire is superior to mechanical throttle if it slows down the throttle response so noticably???

Uneven throttle response during cold weather engine warm-up? When sub freezing weather arrived a few weeks ago my 2010 Prius developed uneven acceleration during engine warm-up. The car was purchased in October and it ha less than 3,000 miles.
Gradual depression of the accelerator results in a very small, tiny in fact, amount of increasing power to the wheels, not in proportion to the usual smooth and responsive amount of cold starts above freezing temperatures.
Continued depression leads to a point about halfway to the floor when the engine, which of course has been running all along, suddenly surges and the car takes off with a jolt of power. Not smooth, impossible to control well and unacceptable. Many would say this is unsafe.
My 2005 Prius never had, and my wife's 2007 does not have this issue. Could be a cold weather related accelerator defect as with the Camrys, but this is not mechanical sticking as was the case with the Camrys, its an electronics error like a faulty sensor or cold start injector.

I 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 .

Feel 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?

I 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?

I 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.

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?

I 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.

Well again my celly has died. I was driving down the road listening to some tunes when i noticed all of a sudden i had no throttle response and when I turned down the music my engine had cut out. Well i tried to start it back up and it was a no go. I tested for spark and I am getting nothing, I replaced the main relay and the distributor. I have new plug wires and NGK spark plugs in. This is my main source of transportation so any leads would be amazing. I have a 91 Celica ST with the 1.6 4AFE.

We love our Touareg, but one things plagues our truck. There is a terrible lag in throttle response. We press the pedal down some, nothing, press some more, little to nothing nothing (like it is starting to crawl), press some more and ZOOM - the truck takes off. Kinda hard to drive like that... Is this expected behavior or is there a programmer to fix it? We have an 06 V8 and have not had any luck finding one so far.

I am leaving from a meeting with my business partner and taking a left turn at about 10mph and very light throttle due to a rough road. All of the sudden I've got nothing. No throttle response and my car starts chugging bad. Then I see the EPC light on. I shut the car off as it sounds like I have only 2 cyls firing. start her back up and boom, normal again. No power loss, no lights, nothing. I immediately thought water pump. not the case though obviously. From what I can tell the EPC will come on for multi misfires. but for it to come on that suddenly for no apparent reason and then just be fine when I shut off and restart, I would assume this may be an ecu or coil issue.

Went to install my intake last night, got everything in and together, started up the car and it idled just fine. Backed it out of the garage, put it in drive and had no throttle response. I was only able to coast. I did some research and tried replacing the fuse, cleaning the battery terminals and took the K&N intake out and replaced it back to stock. Still no change and still have the check engine light on.

First ever failure with a Toyota. We limped home at 25mph this morning. No response with throttle pedal input, but the throttle body did operate in fail safe mode. Throttle pedal checks out with omhs check across the terminals per Toyota manual. I'm looking at having the car transported 45 miles to nearest dealer. I can change the tb out myself but not sure of the electronics. Does the computer have to be programed for a new tb?

I have been getting no throttle response intermittently. I will be driving usually at lower speeds and all of a sudden the engine with slow down and there will be no response to the throttle pedal. It will come back quickly. Also the ESC light sometimes comes on and yesterday I could not set the cruise control. Today it had this problem but the ESC light was off and cruise control worked.

I've noticed that my throttle response is pretty weak. Doesn't seem to just go when ya put the pedal down. I mean it goes but not as fast as i think it should. is this how it is on all our cars? kinda seems like it has a hesitation or something. Anything I could do about this?
