Ford Transmission :: 2006 Expedition - Surging Very Slightly While Cruising Under Very Low Throttle
My 2006 expedition surges very slightly while cruising under very low throttle. Usually most noticeable at 60-65 mph with no headwind.
Took it in and had my mechanic check it out. He confirmed the slight surge and said it felt like the torque converter was locking and unlocking. No codes or pending codes were found related to the power train.
Abs light is on for a bad rear wheel speed sensor. Code for right rear. Checking the sensor showed 3 ohms for right, 5 ohms left ( left is less than a year old on a new wheel bearing.)
Initial thought was the bad sensor is giving bad input confusing the pcm/tcm. But the condition remains with the sensor unplugged.
Driving down the road watching the tach, it does appear that the converter is not staying locked. Condition goes away with more throttle. Motor runs smoothly otherwise with no indications of misfire. Plugs have 50k miles on them, as does the transmission fluid. Fluid is red and smells fine. Never gotten hotter than 210 by the gauge in the pressure port.
Why would it lock/unlock at very low throttle, but lock tight with more throttle? Tps flaking out? Throttle body motor getting twitchy? Can I pull my popup to the hills this weekend?
Sonata NF (2006-10) :: Hard Shifts Under Light To Medium Throttle
I have a 2009 V6 Ltd with about 15k miles. It has always seemed to shift a little too hard from 1st to 2nd and from 2nd to 3rd under light to medium throttle. Does this sound like a transmission ill that can be fixed by adjustments?

I have a '01 7.3 Excursion 2WD. 220,000 miles. It has a 4" exhaust, K&N filter and Edge Reprogrammer set on emission illegal. It gets the best fuel economy and moves out very well for 8000 lbs. Recently, I started to feel a surge while making light throttle acceleration. For example, round a corner at 35 and try to gently resume the 45 Speed limit. It begins to accelerate and then cuts out or surges, sometimes several times. If I lay into it, it responds fine. I have serviced the air filter, the fuel filter, use synthetic Amsoil. I did notice a slight improvement after the service. Less frequent cutting out or surging. I also was in an area where Bio diesel is readily available. I added almost a full tank of B10 Bio and it seemed to work. Changed the fuel filter just after.
It has been cold for NC. This morning it was +14 when I started the truck. It seemed to finally catch on maybe 2 cylinders with lots o' white/ blue smoke. It cleared out in a few minutes and seemed to be hitting on all 8, or at least 7. Once it warmed up, it's fine. But I had the codes p0672, p0674, p0676, p0678. My question is: Is there a common thread in the fact that it appears that I lost 4 glow plugs on the same bank?
One arm chair quarter back's response to the surging, is that the under valve cover injector wiring harness may be breaking down, especially since the truck has 220,000 and the valve covers have never been off. I have a fresh turbo with the good wheel sitting ready. I have just been too lazy to swap it out. Would a fresh set of injectors be a wise choice, when I swap over?
Passat (B5) :: Engine Check Light On And Throttle Start Surging - Water In Tank?
Coming back from Busch Gardens today. Filled up at a Shell. Got on the road and within minutes got a check engine light and the throttle started surging like when you have water in the tank (know from past experience-don't ask). Is the check engine light what would come on if I had water in the tank?
I was able to make it home after adding one bottle of dry-gas but the car is still doing it...major loss of power during mid-level throttle. I was able to keep the engine light from coming on if I was very careful with the throttle and kept the revs around 3K or higher.
Hate to take it to the stealership if not necessary. Burned 1/4 tank of gas on the way home. Should I add a second bottle of dry-gas and top off the tank with fresh gas before taking it in? Don't want to damage injectors or?
Sonata NF (2006-10) :: Mid Range Surging At 50 MPH
I recently bought a 2006 sonata with the 2.4 & automatic. It has 56k miles but is out of warranty (CDN). A lot of times at 50 mph it has a very noticeable surge where the car is not sure what gear it wants to be in (feels like torque converter locking & unlocking). At 60 mph plus it's fine & the tranny shifts smoothly. The fluid is nice & red with no burning smell.

When coming to a stop in my 2007 Hyundai Sonata GLS with a 2.4 4 cyl engine all of a sudden you get something that acts like the car is jerking or surging or rough idling or something. Hard to tell exactly which but if I put it in neutral and rev the engine a little it smooths out. Only happens when coming to a stop. What caused it?

Last Thrusday, my wife couldn't start my Sonata 2010 with 30,350 miles on it. It just clicked and sounded like a dead battery. She had to get a jump start through Hyundai road side service.
I change the battery yesterday (it only had 225 cranking amps) and immediately strange things started happening: lights flickering, engine surging, hard starting, not starting just clicking, gauge lights blink strangely at startup and when switching off ignition, not remembering odometer settings (I set my odo for MPG).
Sonata NF (2006-10) :: Check Engine Light Came On While Driving - P0110 Code
I have a 2006 Sonata, 6 cylendar. Today, the Check Engine light came on while driving home from work (note: there was no difference in performance of the car).
I went to the nearest Auto Zone to pull the code. The code reader came back with P0110. The guy at Auto Zone ran it through their computer and Hyundai didn't even come up in the list of code definitions for P0110. However, for all the other makes and models, this code is for the IAT.
The guy at Auto Zone, just for fun, tried to look up an air intake sensor for a Hyundai Sonata, 2006, and was told that this car does not come equipped with an IAT sensor. What caused the Check Engine light to come on and what do I need to have repaired?
Sonata NF (2006-10) :: Battery And Driver Seat Belt Light Come On While Driving
I replaced my battery yesterday because it died; today while driving the driver seat belt light and battery light came on at the same time. What might be causing this problem? I drive a 2007 Sonata Limited. It was the alternator.

I have a 2008 Sonata Diesel version, and I am getting the engine management light on. All the times i have scanned it, it says - Insufficient air flow to EGR Valve. This gets automatically reset in a day. Now the weird thing - This is happening only if I drive in and around Heathrow airport I have done 100s of miles elsewhere and this problem never occurs. But if I just drive 20 miles to Heathrow, my engine management light always comes on which resets in a day.
I am really confused on what is happening here.

View 9 RepliesSonata NF (2006-10) :: 2009 Auto Throttle Hesitation From Standstill
My Sonata has developed a hesitation when accelerating from a standstill. Sometimes the symptom is worse. I haven't identified any correlation of this symptom with any other scenarios.
Symptom : When at a stand-still, lightly pressing on the gas pedal doesn't result in corresponding slow acceleration, it is only after a certain threshold (of throttle application) has passed that power from the engine is transmitted to the wheels. When this occurs, the result is a jerky start.
In other words, trying to feather the gas pedal to allow a gradual and smooth acceleration from stand-still is not possible when this issue occurs.
I believe the 09' Sonata has a drive by wire throttle correct? If so, could this be a computer calibration issue?
Golf IV / Jetta IV :: Throttle Body Not Working And Car Is Surging
I have a customer that has a 2.0 mk4 with 260000 miles on it..about 20k miles ago we had 6 codes saying throttle body was not working and car was surging, so we ordered a vdo tb, installed it reset tb and it ran fine for 7 months and 20k miles. Again car is surging, so i tried a tb reset. tb was under guarantee so we took advantage and replaced it/reset it and it threw a code within 5 min of driving and hesitating/surging. He is original owner? possible ecu getting sleepy?

I've noticed this when driving for a while now but was never really sure what was causing it. It was usually in 2nd gear and the car would sorta surge on and off boost almost. yesterday i found out that it only occurred when i gave my car partial throttle. It would build boost, let off, build again etc. Full throttle and it was not a problem at all. My car is an 04.5 GLI chipped / 3" exhaust etc etc and would like to know what I can do with this problem.

2009 Limited, 3.3L, 65000 miles.
Car starts, check engine light and ESC light come on. The car has no throttle/pedal response. It will not go above idle speed and it doesn't matter how much the fuel pedal is pressed. So we've turned around and returned to where we started.
The first time I let the car sit for five minutes and started it. No problems for four weeks. Yesterday, we tried that four times and that didn't work. I disconnected the battery for five minutes and the car works normally again.
Sonata NF (2006-10) :: Rhythmic Humming Noise If Give Slight Throttle At Around 50 Mph
09 i4 AUTO 47K miles ... When the car is running at around 50mph and if I give it very slight throttle (enough only to keep speed constant), I would hear this rhythmic humming noise. The hum rhythm has a frequency of about 1/2 second each. It is very muffled, almost like exhaust noise or tire noise. However, if I downshift to 4th gear, keep the same speed, and apply the throttle in the same way, the noise doesn't occur.
