Passat (B5) :: Hesitation When Accelerating From A Stop / At Half Throttle Car Bogs Down

I have a '99 passat 1.8t Tiptronic. 106,000 miles. Recently I've been getting a bad hesitation when accelerating from a stop. At half throttle the car kinda bogs down and hesitates then as the rpms get higher it seems to clear out and accelerate smoother. At the same time the car doesn't have the same sack it used to. I checked he plugs, found them very fouled. Replaced them and the problem got a little better, but definitely still there. There has to be a reason the plugs fouled. There is no CEL so I don't really know what to check first.

Prius (Gen 2) :: Rattle Noise When Accelerating Mid Throttle

My good ole trusty Prius is still running good, change the oil every month (3000-5000 miles) and still drinks oil and a little over half a quart every 1000 miles.. No big deal. Well over the last 20,000 miles I started to notice this off rattle, noise when accelerating mid throttle mostly when up hill. I thought it may have been the timing chain after changing the water pump, spark plugs and using all sorts of fuel additives, but no change.

After time it's only gotten worse, my works buys my fuel (regular 87) but one day I bought my self a tank of super premium, and hey!!! It sounded great, quiet, powerful.

My question is.. Is this because of a worn timing chain making the knock sensor do this, is this because of carbon in the engine? What should I know? I really need to fix this.

Camry :: Throttle Body Valve Was Stuck Open

About, one month ago my car shut off while driving(pretty scary at the time). I pulled of the road and attempted to start it again. Everything looked good there, but as I was making my way home from work it started to act funny. It would not acknowledge me depressing the accelerator. When I got home, I ate supper, then went to have a look.

The car would turn on, but not acknowledge me pressing the accelerator at all, It did however go up to 30 mph at a snails pace as if it was coasting down a hill. I plugged in my code reader, and it read that the Throttle Body Valve was stuck open. I took it off and tore into to it a bit. I noticed the gears inside the TB itself were corroded and the butterfly valve was locked up.

I replaced the part, and tried to turn my car on with the new TB. All the dash lights are in working order, however upon turning the ignition to crank the engine, the whole car system shuts down. No lights no nothing, besides the car door open sound. The car will remain like this regardless of the key position until I have reset the batter(take off the terminals and put them back on) to which the process repeats itself.

The code reader says no codes are stored because I obviously reset the battery. So now am at a standstill.I believe the old TB froze up, because I had to run in through 3 ft standing water during a storm, and then deployed shortly after(I'm in the service) for a few months while letting the car sit.

Civic - Honda :: 1998 - Throttle Getting Stuck Open

We have a 98 Honda Civic that recently developed a problem with the throttle getting stuck open. With the engine off, the throttle will return to the idle position. However, with the engine is running, when the accelerator pedal is pressed, the engine revs increase, but then do not decrease when the pedal is let off. The same thing happens when the throttle is manually opened (not using the cable) with the engine running. The valve for the air intake doe not seem particularly dirty. I cleaned the spring assembly which I initially thought was the problem. The car is sitting the the driveway with both of us moderately terrified of driving it?

Golf/GTI VI :: Throttle Delay When Accelerating From A Stop And Early Shift Into 6th Gear

I recently purchased a 2012 Golf Sportline 2.5 auto. I also currently own a 2006 Jetta and 2008 Rabbit both 2.5 automatics. Both older cars run and drive great with this engine and tranny combination for me. However with the 2012 I really notice a throttle delay when accelerating from a stop and a very early shift into 6th gear when in the gear selector is in drive mode causing engine lugging. Shifts into 6'th at 60 kph doing 1100 RPM.

This I find is very annoying compared to my other two VW's which have better throttle response and shift a little later into 6'th allowing the engine to turn at 1400 RPM allowing for better acceleration without having to kick it down a gear.

I have taken it back to the dealer hoping for a ECM flash update but nothing is available from VW and my vehicle ECM has all other current settings and updates. I ve looked into aftermarket solutions such as the Sprint Booster which allows for a more responsive pedal but based on my other VW's my 2012 should not preform like this.

Santa FE SM (2001-06) :: High Oil Consumption / Throttle Sticky When Accelerating From Lower RPM

2003 Santa Fe, about 142,500 miles, 2.4L, 5-Speed Manual. It appears that oil consumption is 1 quart per 2500 miles.

No leaks present that I can see, no smell, no visible "smoke" from exhaust. I change my oil every 3K, so this doesn't seem too bad for the age and mileage.

Other issue: Throttle seems "sticky", especially when accelerating from lower RPM (under about 1700). I notice this especially when accelerating out of a corner in 2nd gear: If I'm attempting to climb a hill, she'll begin to hesitate as if the throttle isn't responding properly. I'm thinking it's more me, as I've recently gone from driving a 2000 VW Passat V6 to this Santa Fe with less horsepower moving a heavier vehicle. If I keep the RPMs above 2000 or just give the throttle a good press, she'll (usually) not "buck" or hesitate. Is there something I can check for? I've never really experienced this on other 4-cylinders, but those I4's have always been small cars.

Santa FE SM (2001-06) :: Accelerator / Idle / Throttle Stuck Fully

I was driving along nicely, then faced with a climb up the hill, I floored it ... the throttle stuck fully and the revs up to 5000 RPM and the governor kicked in, zoom ... hmmm zoom hmmm .. I was lucky cuz I shut off the engine and was able to coast back down to my driveway. No code reader, I decided "how hard can that be" since it happened once before and then worked ok for 6 months ... maybe a linkage, etc

A friend looked at it and tried the old process of elimition ... unplugging the MAss Air Flow connector ... trying it ... then the TPS on the throttle body. He suspected one or both. So I replaced them... happy to get the sucker started without revving uncontrollably. But the pedal was sticky, the idle speed too high and when you press the brake pedal ( and nothing else ) the car stalls, putt putt putt kerplunk. Starts up again tho. but impossible to drive like this. So I gets me a code reader .. follow the directions and this is what I get now

P0441 Evaporative Emission system Incorrect Purge Flow ( this is an easy one even for me ... the engine light came on last time I fueled up - gas cap was not turned enough ) no brainer

P0122 Throttle / Pedal Position Sensor A Circuit Low Input

P0101 MAss or Volume Air Flow Circuit Range / PErformance

P0222 Throttle / Pedal Position Sensor B Circuit Low Input

P2119 Throttle Actuator Control Throttle Body Range / PErformance

P2112 Throttle Actuator Control System Stuck Closed

P2422 Evaporative Emission System Vent Valve Stuck Closed

Puzzling since whatever broke started working again spontaneously last time. I figure, it cannot be all the above at the same time .. perhaps one of the early sensors?

Ford 7.3L Power Stroke (1999-2003) :: Alternator Light Comes On While Accelerating And Goes Off During No Throttle While Cold

Background: '01 Excursion 7.3 4WD, 264,xxx miles, batteries less than three years old, new alternator [URL] .... , using an Edge Insight for digital readings.

Problem: I replaced the alternator about three weeks ago, first week all normal. Second week alt/battery idiot light comes on, then to add more frustration it is consistently inconsistent in its reading.

The volts (upon starting) jump around 11.6 - 12.1 when first starting. The light comes on while accelerating and goes off during no throttle while cold.

After warm-up the light will come on intermittently even though the reading is 13.0>, but never during off throttle.

It seems to do this more when cold but it does not completely stop when it's warm. Yes, I don't think that should be a factor but it is a reality .

I'm thinking it's a bad voltage regulator.

Ford Super Duty (1999-2016) :: Buck Or Chug At Like Quarter Throttle While Accelerating

So running into an issue with boost numbers. Factory gauge reads between 20-30lbs on throttle, but I have a SCT x4 and it only reads 3lbs and at idle it only reads .25-.89 somewhere around that range. Are these numbers accurate?

Also, it has developed a sort of buck or chug at like quarter throttle while accelerating, it's sluggish leaving stop signs etc. and it sounds like the waste gate or blow off it holding on even after I let off of the throttle.

Santa Fe (CM - 2007-12) :: 2008 - Accelerator Pedal Stuck Open At Full Throttle

I have a 2008 Santa Fe Limited and am having a major problem. On 3 different occasions, the accelerator pedal has stuck open at full throttle. At first I dismissed the problem as a fluke or the floormat and pedal getting stuck together.

This week while on vacation with my family in Myrtle Beach, SC, I was pulling onto a 4 lane and had to "punch it" from a dead stop to get up to speed with the other vehicles. When I got up to the desired speed I let off of the accelerator pedal and to my dismay the vehicle kept going. I told my family to hold on and immediately hit the brake and safely pulled into the median while the vehicle was still surging. With my foot on the brake my wife put it in neutral and the engine sounded like it was going to blow up. I checked to see if the floormat and accelerator pedal was stuck together somehow and they were not touching. I do not know if it was me freeing up the pedal with my foot or if the vehicle some how on it's own finally reved back down to normal RPM's.

In essence my family and I were in a runaway vehicle and luckily the braking system was strong enough to safely stop us while at full throttle.

This was a scary experience for my wife and I and a horrifying experience for my children. It was the exact situation Toyota had a couple of years ago with the accelerator sticking on their Prius models.

Is the accelerator system a mechanical one with a throttle cable going to the throttle body or is everything computerized. I do not know if it is a mechanical or computer problem.

Ford F-150 (2004-2008) :: Truck Shut Off While Driving / Throttle Actuator Stuck Closed

I am usually on 6.0 site and don't know much about a 5.4 gasser, hope to get some tech info. My buddy was driving to my house yesterday and his 06 F-150 with a 5.4 liter just shut off while driving. He got it restarted on first try, all engine vitals normal. I sent him to Advance Auto Parts and they pulled codes; P-2112 and P-2104 and throttle actuator stuck closed. Engine is running fine and he has driven it about 100 miles since yesterday with no problems. 06 F-150 5.4 liter 58,000 miles.

Ford Ranger / B-Series :: Throttle Stuck Open Causing Truck To Move Forward When In 1st Gear

Have a 99 Ranger XLT, 4 cyl, manual transmission with 191K miles. Was running good as ever last night but went to start it this morning and throttle's stuck open, causing truck to move forward when in 1st gear. Even with clutch in, near impossible to get vehicle in or out of gear. Managed to get it into reverse, but truck was having none of it. What is the cause or causes of my trouble? Or how much the repairs might cost? I'm on the road so no chance of doing this myself.

Lexus GS 2006-11 :: 2008 GS460 Stuck In 1st Gear For About 10 - 15 Seconds When Accelerating From A Stop

2008 GS460 ... When accelerating from a stop sign/stop light it get's stuck in 1st gear for about 10 - 15 seconds before it shift to second gear. I notice this as the engine rev's high and is not shifting. Shifter is in Automatic and not manual mode. Happened at least 4 times in the past 2 weeks. Dealership is unable to replicate the issue and transmission checks out fine. Guess I have to wait until transmission get's stuck in gear before I can bring it back in.

Passat (B5) :: Delayed Throttle Response

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 .

Passat (B5) :: How To Reset The Throttle Sensor

so i went to a car show yesterday and left my hood open! i was walking around and when i came back to my car to leave i started it and i had cel, my asr light was on and my engine felt light it was misfiring on all 4 cyl. so im looking at everything under the hood and notice that some funny guy unplugged my throttle wire! ok no big deal! plugged it in, turned it back on and all i had was a cel! i cleared it and it was fine till i started driving home! i though it was a boost leak but i was only boosting at a peak of 9 psi! driving there it was a normal 11. i know its not a boost leak becuz i had one last week and did a BLT! could unhooking my throttle body and starting up be causing it not to go to WOT??? if so how can i reset the throttle sensor?

Passat (B7) :: Delay In Throttle Response?

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?

Passat (B7) :: Odd Throttle Response When Cold - Little Acceleration

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?

Passat (B6) :: Hard Jerk Around 4k Rpm With Heavy Throttle

I have a 07 20T and today when I went to pass someone on the highway I punched the throttle and the car rev'd up and it started to jerk really hard as if it was not catching the next gear. So I let off the gas and everything went back to normal. Under normal driving the car drives normal and fine, its only when you give it some hard throttle and when it hits high rpm's it jerks, it feels like the car wants to stall. I have 30k miles on it.
