Golf VI 2.5 automatic... I seemed to notice a dead spot in the throttle when taking off from a light. You press the gas, nothing seems to happen. To start from a stop sign, you have to really give the car some juice to get going, which ends up being too much throttle and sucks gas. In other words, very difficult to take off at a moderate pace from a stop. Seems like all or nothing.
View 13 RepliesI have a 1987 ford f150 with a EFI throttle bodied 5.0L (302), and I have taken it to a mechanic multiple times because for one it has a dead spot in the throttle and it dies when you let off the gas at a stop light or sign. But the mechanic said he checked everything he knew to check and found nothing wrong with it. I also had my cousin read the computer previous to this and we couldn't pull the codes from it.
View 2 RepliesWhere to find this wiring diagram? I was getting hesitation in my throttle and the EPC light kept going on.. So I did some looking and found that 2 wires pulled out of the plug in the cowl harness... There are like 5 plugs under there, and these 2 wires were pulled clean.. So I cant tell which one goes to which... I know its definitely part of the 4 wires going to my pedal...
View 2 RepliesI have a 2011 GTI which has about 46k miles on it. The car is stock other than some VagCom stuff. Over the last few months I have noticed a worsening problem which is getting bad enough to start being annoying. Under very light throttle such as cruising along or rolling off the throttle to shift, the car has a slight miss, almost like it's surging. It happens in any gear, typically around 1500 - 2200 rpm, and I first noticed it actually on the highway using cruise. It seems to happen most before the car gets nice and warm. It has not thrown a CEL, but I have scanned it and found some misfire codes, although I believe those to be from a really rough cold start which sporadically happens maybe once every six months (last time a couple weeks ago).
I have it booked into the dealer but I can't get there for a couple weeks. I don't think it's coil or injector related because it runs fine under high load and high rpm. Fuel filter has maybe 2500 miles on it, always use Shell 91. I really think it's probably carbon buildup but I am hoping the dealer doesn't just give it the old "cannot replicate" since the car is not triggering a CIL yet. It's pretty obvious when you drive it though that something is off. If they play that game I'll probably just go ahead and do it myself.
Having throttle hesitation problems. This is the 3rd time I have had it in for this problem and they can't figure out what is wrong. The vehicle moves slightly forward from a stop and then goes dead for a few seconds then seems to recover and go.
View 11 RepliesSo among the other annoyances my 92 Ranger 4.0 auto has it has a hesitation before it starts spinning the tires under full throttle from a dead stop. It's the 4.0 automatic. I thought it would have more power than it actually does being use to a 2.5 auto. But this 92 4.0 runs and drives good. I've gotten it tuned up with new motorcraft wires, plugs, new coil, fuel filter, fuel pump assembly, fuel pressure regulator, air filter, idle air valve, new O2 sensor, new Dynomax muffler. I can't find any vacuum leaks. The engine idles slightly rough after you start it up from it sitting for a few hours, but quickly smooths out as soon as you start driving it.
This one here has no EGR. Transmission feels good, may have even been replaced by previous owner before we got it. It shifts good and the fluid is clean and the transmission is the cleanest part under the whole truck. No way of knowing for sure. The truck currently has 111,000 miles and I did all that stuff when we got it at 101,000 miles. So what could it be? I'm thinking a lazy injector or could it be the catalytic converter? Or could it be the throttle body? I know I once had a BBK throttle body on it and it made the world of difference in off the line power but it kept throwing too rich/lean condition and a TPS code so I had to return it. It sucks because it did wake up the motor. I returned it and since then the Check Engine Light hasn't come back on.
When I first got my car it had a flat spot while driving hard at higher rpms. Almost as if something were actually holding the car back, it would pull nice up to that spot and then just almost die off. I eventually got unitronic flash and it seemed better but it was still doing it. Later companies started coming out with dsg flashes and this seemed to be the remedy but I now have hpa dsg flash and it still does it from time to to time. Could this be a faulty coilpack, or an issue with the intake manifold valve that changes over at higher rpms?
View 4 RepliesGot a problem with my R. 134k miles. About 4 months ago I had similar problems and was told it was a bad MAF. Of course wasn't covered by my warranty, so I decided to just give it a good cleaning and car ran fine up till now. Just started doing the same thing today. Doesn't want to idle, taking off is really hesitant then it just goes. Trans seems like it is struggling to find the correct gear sometimes when coming to a stop or taking off, sometimes jerks hard, maybe throttle position sensor, or idle control? Once you are moving it drives fine, only very low speeds and idling are the problem. Trying to avoid going to the dealership. What this could be? MAF need cleaned again or just replaced?
View 4 RepliesSo this morning when I started my car to warm up everything was fine. I went inside to make some coffee and I heard my idle change slightly and didn't think to much about it but when I got in I could feel my car shaking a little bit then when I pulled off my road there was a little hesitation in first gear taking off and when I would shift I would get a little rev hang between gears. So I've realized when idling its slightly fluctuating between 6-7 hundred rpm. I have no loss of power and it has not hesitated since the first take off. I'm thinking its something to deal with air. I checked my airbox and realized the bolt closest to the battery wasn't threaded so I fixed that and tried looking for any leaks but haven't found anything.
View 4 RepliesHave any other PP 6MT owners experienced strange throttle hesitation while shifting with a APR 1.2 HO tune? I know what turbo lag feels like, but it is almost as if the throttle position is not being read for 1-2 seconds after shifting.
No matter how hard/fast I shift, I can't get the tires to chirp, even shifting at high RPM. When I watch my speedo after shifting, the needle does not move at all until the delay ends, and of course it moves fast when the boost builds. But for 1-1.5 seconds after shifting, with the pedal to the floor, I would expect some acceleration, even not at full boost.
Even when not shifting, and going from no throttle to medium/full throttle, there is a delay with no acceleration and no significant noise/rev build.
I don't remember this being as pronounced before I was tuned. Also, I had GFB DV+ installed about the same time, but I would expect the DV+ to make this better, not worse.
I finally decided to take my car in to the dealership for this random split second hesitation that mostly happens in first gear. I have 8600 miles on the car and it has done it since the day I bought it. I thought it might have been compressor related from running the AC. I have tried driving with no AC and ESP off and it still does it.
So I take it in and they decided to let the new guy work on my car. I take him on a ride (AC and ESP off) and sure enough it does it nice and strong for him to feel it. I was happy so we went back to the dealership and they gave me a 2.slow rental and I was on my way. 24 hours later they call and tell me, "Ron we believe it might be your throttle body so we're waiting on the regional master tech to get his opinion before we put a $750 part on your car".
I'm like "ok, whatever you say, just call me tomorrow with an update because I don't want it back till it's fixed". They call me the next day to inform me that my brake light switch was faulty ($10.25), they replaced my wiper blades, adjusted my wiper arms and the car was ready to be picked up.
Now that I have it back I can say driving it now that it's acting normal is an adjustment. My mind expect that hiccup but it doesn't happen, at least not most of the time. I'm not completely convinced that this hesitation is gone because I think I felt it happen once yesterday. Time will tell... In the mean time it is 95% cured.
What are the symptoms of a bad o2 sensor, 2.0.. My son is having some problems with his car hesitating when he gets into the throttle and the only codes we are getting shows bad O2 sensor pre cat.
View 2 RepliesI'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?

Car is a 20th, 1.8t 6-speed.
I noticed something the other day that is happening occasionally on acceleration. At partial throttle, usually pulling away from a light or stop sign, I get this weird hesitation. It only happens at partial throttle and usually only in first, sometimes in second. As the RPMs increase up to around 3k, it's as if I lose power for a second. You can feel the car stop accelerating for a second, then it begins to pull again.
If it's under heavy acceleration it never happens. It doesn't feel like the clutch slipping, more like the motor hesitating, but there's no noises or missing or anything like that. The RPMs don't jump up or anything. It's like for a second it's making no power, then it comes back.
I decided to take out the throttle body and clean it with throttle body cleaner that I got from autozone, after I put everything back, I started my car and the motor was shaking and smoking a lot out the muffler and just would not be drivable at all. the RPM was just going up and down and hesitating bad. later I took off the spark plugs and they were very much burnt black at the tips and that is probably not normal right? but I replaced them with NGK BKR7E spark plugs and it still gave me the problem.
View 13 Replies I have been experiencing this one for quite a while now. The car is a 2003 GTI VR6 24v. It is stock other than a 3" hole in the bottom of the airbox to pull in cooler air.
When I am sitting in traffic, and in 1st or 2nd gear, keeping a consistent speed (10-15mph) and application of the throttle (not moving my foot at all), the car sometimes just decelerates/hesitates/bucks a little by itself, and kind of feels like it is hiccuping or not getting enough air or something.
At high rpm, or in any gear above 2nd, I don't feel the hesitation and the engine runs great and pulls hard. No MIL lights on the dash, and no other problems with it.
Is this normal for manual VW's? Or maybe the hesitation coming from the engine not getting a consistent airflow from the hole in the airbox?
So,I have a mk4 GTI vr6 . I've got an idle that moves about 25 rmps up and down. As well as the throttle hesitation between 2.000 and 3500 rpms only at mid throttle. Has a kinda new maf. That I cleaned. clean THrottle body kinda new coil pack and wires , new plugs. Tried a lot it all worked but it's still there.
View 11 RepliesI don't put many miles on my car, so even though I'm going on 2 years my 2010 GTI (6 speed manual) only has 11k miles on it. Over the last few months I have notice that when starting out in first gear on a hill, as I let the clutch out I will sometimes (not always) hear a squealing noise that isn't insanely loud but definitely noticeable and sounds like a cross between chewbacca and an elephant. It goes away once the clutch is fully let out and I start moving. Over the last couple days I've noticed a hesitation in the throttle occasionally, as if the power is just dying. But, the rpms don't suddenly rev up when this happens (as I would expect if the clutch were slipping). It just feels like the power is dying and hitting the gas has no effect -- the car just slows down. Happened today in 4th gear going about 45 mph -- car just started to slow. 5-10 seconds later it recovered.
Could this all be due to my clutch? If so, can it be adjusted or does it require a new clutch? It's under warranty. Problem is it's intermittent and I just know I'll drive all the way out to the dealer and it won't do it on command. I am APR stage 1. But I don't drive hard at all.
My GTI is the first FWD car I've had since 1985, so the issue that I'm having may be just me adapting to a front drive platform. Here's what's happening: when I nail the throttle in 3rd or 4th gear, on or about 4K rpm or above, the car feels as if it's hesitating slightly as the revs climb.
It accelerates fiercely (I have the JB1, and I had the Neuspeed Power Module before it, and it's reacted the same way with each mod), and it's almost as if the front end of the car is lifting and struggling for traction (although the traction control light doesn't come on).
Is what I'm experiencing normal FWD behavior? Is it the beginning of torque steer? I only notice this at full throttle--not noticeable at all at partial throttle. Also, it doesn't happen consistently. My car is a performance package manual.
This is kinda hard to describe but here it goes. I have a 2012 Turbo with 33K miles which I have owned since new.
Like I said, it is hard to explain but it seems like the steering wheel has a dead spot when driving. Feels like you have a magnet between the steering wheel and the column. As you are driving, it seems like you overcompensate trying to keep the car in a straight line. Asked the techs at the dealer twice already and they say this is normal for being electric.
Gotta tell you, on long rides feels like I just flew an old C-47 (DC-3) for ten hours straight!
Over the past few months my '13 350 occasionally seems to hesitate when starting from a light, in a parking spot, in general no/low speed maneuvers. It doesn't do it every time, and it's not a hesitation with engine bucking, backfire, or noise. It just feels like the power takes a few seconds to come on when I hit the pedal. Sometimes. It has been interesting a few times on highway on-ramps...
At first I thought it was my accelerator technique, using the wrong foot angle, but I've been careful to apply the pedal correctly. Since it doesn't feel like the classic engine miss I was wondering if there are any other things to consider, such as transmission (hopefully a software update or something else simple) or anything else.
