Passat (B6) :: 2006 Engine Will Give Surge Of Power And Then Kind Of Slow Down
Jul 2, 2013
I just bought a 2006 Passat 2.0T FSI about 3 weeks ago, love the car so far. My only concern is within the last week i have started to have a little bit of a lack of power. The engine will give a surge of power and then kind of slow down for a minute then a surge of power and then slow down. Also the other day i started it up and it had a little bit of a rough idle until it warmed up, don't know if these are related. Has right around 91K miles right now.

My 06 suburban is causing problems. Every time I come up to a stop sign or intersection and slow down then give it some gas it seems to stall. I then have to take my foot off the gas and wait a second and then slowly give it gas again. The engine isn't stalling though . I had it in to midas and they cleaned/ washed out the throttle area ?

7.3 2001 model starts ok at 32-35 F. Feels a bit sluggish / slow response on the road. Reach a hill after 3-4 miles. Engine temp then beginning to go above low level mark. 100 meters up the hill, going around 30 mph there is a sudden surge in the throttle although my pedal is steady. Going back a few minutes later, on flat ground at bottom of hill and with no accelerator pressure, the engine suddenly stalls. Starts fine again after I stop. The same history actually repeated on two separate days recdently on the same hill. CPS is recently replaced. Had some jerking before that, but not the behavior explained above. Current CPS is Delphi light grey. Recent fuel filter change and oil change as well

My Wife has a 2006 Chevy Malibu Maxx Lt, we recently had a series of factory safety recalls performed. Now we have a message coming up saying "POWER STEERING" and the steering wheel is tight and kind of jerky. We didn't have this much trouble before we had the recalls done.

I dont know if this is related but my ignition switch went a few weeks ago, I got the part in the mail this week and was planning on changing it today, but a few days ago my 99 Passat v6 started bucking, kinda like it did when i needed motor mounts...but my engine is really weak and rough. I opened the hood and saw that my air filter hose was disconnected right after the MAF (or at least i think its the MAF).... I don't know how long its been sucking up dirty air. but does that sound like they are related? a friend of mine said if i can see the butterfly valve in the air hose, open it up and spray a can of carb cleaner in it, put the filter back on, start the car and let it run, then do it again with another can and it should fix it. I cant see the butterfly air valve in the hose, since the hose goes down behind the engine. Should i just spray it in anyway? or does have to be press on the gas pedal...

Earlier this winter and last year, the forum had discussed the occasional fast idle in the 3.6L. Symptoms include the engine idling at 950-1000 RPM and the car feeling like it wants to surge forward. I had the problem twice during heavy snowstorms in February, but nothing really since...until this past week.
The weather here in Chicago has been in the early 90s and I've had the AC cranked. At the same point, I've had the fast idle event occur at least 5-6 times in the past week. Almost every time it has occurred while moving in very heavy traffic. Have others seen something similar in very hot weather?

I have a 97 F150 with a 4.2. It has started to surge or stall out when I slow down sometimes. It doesn't do this all the time. I replaced the fuel filter about 2 mths ago and replaced the fuel pressure regulator then also. Would the tps have anything to do with it? I haven't had a scan done yet. Thought I would try here first because at one time someone has removed the two cats and the check engine is on all the time.

Car has 252k miles runs ruff after engine warms up, looses power, if I give more gas, car will sputter, but rev up to 5k engine smoothes out. This situation constantly comes and goes.

My truck has been having idle surge, low engine power, says stable tracks is off, computer said TPS pedal sensor. I replaced it. Within 3-4 days my truck does the same thing. I turn it off and eventually my truck runs fine with the exception of my engine light is on truck runs good. I put the computer on it again while the truck running bad and it continues to say it is the TPS sensor.

I have a 1999 F350 200,000 miles. Now getting an intermittent engine light. Still runs well, although once or twice I felt a momentary surge at highway speeds. The light is on intermittently about 1/2 time. I read the codes and the following codes, as in the thread title, came up:
P0280 - ICP circuit out of range - low
P0113 - intake air temp sensor circuit - high input
P0470 - Exhaust back pressure sensor circuit malfunction
P0478 - Exhaust pressure control valve - high input
What would make these all code at the same time? Would these not make a noticeable problem driving? And how do I resolve these?

Well I put some HID light in my 2001.5 GLX Passat an I notice that they are aiming kind of low. I know which slots are what. Ones for highering and lowering and the others from side to side. But when I'm trying to adjust them the up and down they work but when I'm trying to adjust the side to side they seem like they aren't moving. Which is a better way to tell? I put it right next to a wall 25 feet away in the dark but I really couldn't tell still. Plus it's not a straight line either. Since I have the perjecter lights their should be a cut off line right? Also is it like turning it right to make the light go right or left to go right, for the side adjustments?

Have a Accent GLS 1.6L, 92,000 miles on it the issue is what I stated above.
Basically back in March I started having issues with my car and it seemed like it was misfiring or something of the sorts at first I thought it was the IAC motor because it would only intermittently kind of "choke" if you will and it only did it while I was idling and in drive. So before I decided to go further with the IAC motor I decided to take it and have the throttle body cleaned, but it eventually started to do it again. After that I had my fuel injectors cleaned and that didn't work much at all. Kept going until a couple months ago when it actually set off a check engine light and it started doing it almost violently.
Check engine light came up with the result that coil 2 is misfiring and I went about replacing the spark plugs and the boot to one of the coils and that made the issue go away no check engine light, no nothing. Past couple days it's been doing it very very occasionally but yet still doing it.
I don't have a whole lot of cash but I need a solution quickly because this is starting to become a pain I don't want it to become so bad that I'm without a vehicle that is operating properly again.
Only thing I can note is that now it is very occasional, and when the car could be otherwise be considered "cold" and often I can't make it repeat the same thing. Had oil above cylinders when I had the plugs replaced.

I have a buddy who has an 01 B5 w/ 1.8t and 5 speed. He asked me to try and find out why it has been making a mysterious noise. I do all my own work, so I know a few things, but this noise has me stumped.
On startup, it will make an almost ratcheting kind of sound. Clattery, grumbly ratcheting sound... Goes away in a few seconds. It will also occasionally do this on acceleration.
Now, I am not hugely familiar with the 1.8t (in fact, my VW experience is largely a B4 TDI) so I'm not sure where to start.
One note though- I changed his oil for him, and the first startup right after the oil change the sound almost didn't happen at all. From then on resumed its obnoxious habit.
What this could be? Engine? Tranny? Something else? I didn't get a response over in the 1.8t area so I'm trying here.
Just recently his turbo has decided to contribute very little to power. You can hear it spool a little bit, but it's not what it used to be.
Just recently he had to have his intercooler replaced due to running over a semi tire. I have yet to pull his belly pan to look for loose fittings.

Just curious. I installed a set of Drive Gear springs on my auto passat and I have a "swoosh" kind of noise coming from I think it's the left front. (I think, might come from the others) It happens a lot on small bumps.

When I started the V^ Passat today it made a fluttering/imitation purring kind of sound...not re-assuring at all. What it could indicate? It only lasted a second then fadded out and ran fine.
maybe a belt tensioner or oil pressure regulator or something like that getting up to snuf?

I have a 1999 Ford F450 Tow truck with a 7.3 turbo. It loses power and misses when I give it gas but when driving normal speed no problems.
I had a ford technician look at problem with a computer and he said number 8 injector . Today number 8 was changed.
Test drove it same problem. I also changed th fuel filter. And I emptied the tank to make sure No water

I was driving the car and suddenly started to vibrate and to give signs of stopping. The car doesn't have power now. I stopped the engine then start it. The idle rpm was instable and the engine stopped by himself. After i tryed harder to start, the engine started and the message Engine Fault Workshop and the sparking plug sensor apeared blinking.With that message and sensor notification on screen the car sounds normal and the rpm is idling..but after a restart the messages disappeared and the engine was again going wrong.

2003 Ford Sport Trac with 4.0L SOHC engine
I started having this problem after I decided to do a tune up because of another minor unrelated problem (start up taking 2+ cranks sometimes and fine when gas is full... I'm going to replace the fuel pump for that but not until i resolve the more pressing issue)
Before the problem I had spark plugs and wires (all but #3) replaced by my dad and he also put in some Fuel Cleaner into the gas tank. He took it to a local mechanic and had the mechanic replace the #3 spark and wire and check the others and also replace the fuel filter.
After that my car was taken to jiffy lube where engine oil was changed... as well something else but I dont know what because no one is able to tell me.... my dad had one of his employees take it and the employee took it upon himself to get other things done but he doesn't know what.
And then when I got my car back after the weekend is when this issue started.
First I noticed a rattling (like a plastic is caught on a fan blade and it is hitting something as it goes round and round) right after engine is started. And on the roads, when I try to accelerate, it will accelerate- but very slowly as if my engine had no power.
When I floor my gas pedal, the car will continue to drive at a constant speed and I can start to hear a really fast rattling which I am not sure if it is the same thing making the rattling sound I hear at start up.
I've gotten the following codes : 300, 301, 303, 316
I have since then had my spark plugs rechecked, wires for #1, 2, 3 and 4 replaced with another brand. There was no long term change but I have noticed that every time messed with the wires (when spark plugs were changed, when wires were changed and when sparks were checked... etc) for about 3 drives right after it the car feels more powerful and smooth and then it will go back to driving like crap.
I have also changed the CKP sensor (advice of the Auto Zone) and there has been no change.
I have also replaced the coil pack this weekend and no change.
I have bought the more expensive wires but didn't change them since 2nd set for 1, 2, 3 and 4 has not made changes.
Currently: Only thing I have more noticed is that the car when first driven, feels okay at start up. I can accelerate from 0 to 30 with decent power and time and as long as i dont floor the gas and only lightly depress the gas the car will continue to accelerate with decent power and speed.
However, anytime the engine is strained (like going up a hill) I loose speed. and AFTER any time the engine is strained, i will no longer be able to accelerate with decent power and time.
The car at this point feels like it it trying, almost sounds and feels gritty if that makes any sense, and if i try to at least keep speed, the engine sounds change but no increase in speed. At this point I usually just try tapping lightly on the gas and it will eventually get upto 30mph and of course more effort to go beyond and continually increase the speed.
It takes me a good few minutes for me to go from 0 to 35 and another few minutes to get upto 45. (Now everyone drives around me after a complete stop because I cannot even get to 20 right away like most normal working cars.)
I really would hate to replace one part at a time to play guess and check but I also don't know any true mechanics in the area that can really drive, listen and look and determine what exactly is going on without playing guess and check with every little and big parts that are involved. I have seen some people replace the intake manifold, O2 sensors, CKP/CAM sensors, cylinders...

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.

I have yet another issue with my Hyundai Accent. It seems to me that I hear engine valve knocking. Here tech. details:
- This happens around 1100-2000 rpm.
- The car currently has 11500 KM.
- 3 oil changes so far - using Mobil 1 - 10W30.
- I put in regular gas.
- No mods, only bug guard.
I drive slow - slow acceleration and I noticed sometime ago that there was a knock coming from an engine at about 1400-1700 RPM, however now I can hear it anywhere from 1100 to 2000 rpm. I can hear it very well when I drive along curbs and walls since engine sound bounces off it. I have automatic gear box and therefore I don't know how to test it further ( on manual I would have put some load on the engine by switching into high gear and pressing gas - make engine struggle a bit ). It might be noise from injector but I don't know. Also I don't know if Accent 2010 has self-adjusting valves or not.

I posted the following issue a year ago about my car, but the problem continues. when my 06 v8 phaeton is cold, there is variable engine rpm's with my foot steady on the gas at low speed and a flat surface. ie 1500 to 1700 to 1500 to 1700 etc. i can hear it feel it but it's subtle. the engine starts easy and runs perfect otherwise.
