Passat (B6) :: Rough Idle When In Drive / Slight Loss Of Power With Horrible Gas Mileage
My 07 2.0T (101k mi.) Passat idles roughly when in the drive position (at a stop light, or sign, etc.), the engine sounds "gruffy", and suffers from a slight loss of power with horrible gas milage. I've had spark plugs and the coil pack replaced two weeks ago, and still can't seem to find the source. There are no misfire codes or any others showing up. From reading many posts here, I've found that a common issue is carbon build up for similar symptoms of my car. Do I need fuel injector cleaner, and or valve stem cleaner, etc? As far as the possibility of cleaning out the intake valve, I only open the hood to add oil, washer fluid, check my oil, and wipe down the engine.
View 5 RepliesGmc - Safari :: Slight Rough Idle With Noticeable Dimming Of Dash Lights In Dark At Idle?
2000' GMC safari's electrical system. To begin, she has 95,000mi, an although that's about a year old, a duralast gold battery about the same age, and 13.8 volts at idle on the meter at the battery. The problem, over the past couple of weeks, I'll start it and drive off as normal, an the thing wants to stall for about two seconds. After that, no problem whatsoever. One time, it actually did stall on me, and everything went dead for a couple of minutes, no juice whatsoever; noticed that even the clock in the radio read 12:00. After a few minutes, I tried to turn the key again, and it started right up. This a.m., I went to start the van, and it initially would not turn over. The started motor turned but in a weak manor. At that point we went completely dead again, no electricity whatsoever.
The strangest thing is what happened next, I pulled the hood latch release as I was about to investigate and noticed the guages on the dash move when I did, power was back. The van then started but barely, and when it did it stumbled for a few seconds before driving off without so much as a hiccup the rest of the day. The only other possibly related symptom would be a slight rough idle combined with a just noticeable dimming of the dash lights in the dark at idle. Also, I should mention that I have checked the battery terminals and they are tight and clean, the van is in excellent shape mechanically, averaging 20mpg combined, smooth acceleration, no leaks, "using oil", white or black smoke, etc. Plugs, cap, rotor, and pcv are recent. Egr and maf are both clear.
Golf IV R32 :: Rough Idle With Slight Miss Under Acceleration
Woke up to go to work and it started up with a rough idle, got a block down the road and it had a slight miss under acceleration. Guessing its a bad coil, I've got a spare featured I'd play I I mini miny moe when I get home unless.

My moms has a 2010 Elantra with 30,000kms on the clock, and we have noticed since new when the vehicle is started cold in the morning it seems to run rough for about 30-60 seconds then stabilizes.
It's almost like it has a slight misfire, or slight fuel flooded from sitting overnight. Now if course we have taken it to the dealership twice for this issue and dropped it off overnight for a cold start, and both times they cannot re-produce the problem.......surprise.
Dodge - Stratus :: 2006 SXT Rough Idle - Slight Sputtering Noise When Not In Motion
Today I went and test drove a used 2006 Dodge Stratus SXT from a private party. Everything about the car was great except it had a bit of a rough idle; there was a slight sputtering noise when not in motion, and the car itself vibrated very slightly. It didn't bother me too much while I was driving because it accelerated and shifted fine and the engine sounded very strong, otherwise.
When the test drive was over I pointed out the noise to the owner, and he admitted that he had mis-timed the timing belt slightly which was causing the sputtering (he is a mechanic and replaced it himself). I was worried about this, but I did some research when I got home and learned that this model of Stratus has a non-interference engine.
My question is this: should that timing belt be a deal breaker for me? Will this cause major mechanical issues down the road? I know it will reduce power but I only really need the car to commute, so I don't mind if I'm not toe-to-toe with a Challenger. I'm just worried it will eventually cause a costly problem.
Chevrolet - 1500 :: Slight Rough Idle / Loss Of Power - Vacuum Leak
I have a misfire in the 6 cylinder on my 98 Chevy c1500 5.7l 350 v8 2wd. I changed the spark plugs and wires, cap and rotor, and changed the spider injector i put the spider injector in from another engine I had. After doing all this the code still comes up. The truck runs fine and except it idles slight rough not bad at all and now it says I have a vacuum leak and while I'm driving you can feel the loss of power. I tried all the ways to do it like on YouTube. What is wrong with my truck?

I have a Rough Idle & sometimes a hesitation or stumble on acceleration. I cleaned the MAF & IAC motor & Air & Fuel Filters are new. I got a 20890 scanner & ran test 6 53 as suggested in many posts by BlueGrass. Here are My results & what They Convert to.

I'm guessing the cop's are ok & probably need plugs? I was hoping to just swap a coil. Too cold to do plugs & truck won't fit in my garage.
Ford Super Duty (1999-2016) :: Slight Rough Idle After Couple Of Minutes When Start The Truck
I have a 99 F350 with a V10. I just replaced all the spark plugs and a bad coil which solved the very bad misfire I had going on. I also just changed the fuel pump and fuel filter.
When I start the truck, it idles just fine, nice and smooth. After sitting there for a short bit, maybe a couple minutes, it starts to idle rough, not so rough that it's about to shut off, just a little rough. This lasts maybe a minute and then goes back to nice and smooth and stays that way.
I've thought maybe the EGR valve or Idle air control valve but I'm not sure if I'm way off or sort of close.
Ford Excursion :: 2003 - Rough Idle - Puff Of White Smoke On Cold Startup - Slight Exhaust Leak
I've been chasing a problem all summer. Began with crappy batteries dying intermittently. I replaced the batteries, FICM, finally cleaned EGR valve and replaced ICP with pigtail. The problem is still persistent. Basically a rough idle, puff of whit smoke on cold startup, rough running at around 1500 rpms( driving at 50 mph). The ICP was soaked in oil so i was confident replacing it would finally cure my issues. It actually got worse with the rough idle turning to a surging idle and quite rumbly at 50 mph speed. I guess its time to look to injector issues but i thought id check if after replacing icp/ cleaning egr. I also have a slight exhaust leak at turbo out that i can see. The clamp is not seated properly. This after turbo connection to exhaust.

I just purchased a 2008 passat, 2.0T 6spd manual last night and I noticed today, when sitting at a stop sign it has slight idle issues, (goes up about 200-400rpms) then back down to normal idle. Doesn't seem to be causing any issues, its just pretty annoying, and everyone next to me thinks I'm trying to race them.

2003 passat wagon 2.8l v6 with p0421 and p0431...a slight miss as well...
Cold start up is fine and initial driving. After car warms, there is a slight shutter at idle (just occasionally) and upon acceleration with low rpms. (It really feels like a miss) Went to AutoZone and came back with the codes above. I thought it might need a new coil but now I am not really sure. I want my performance back but seriously doubt cats are bad at the same time.
Passat (B6) :: 2008 VR6 - Slight Rattling Sound Coming From Driver Side Of Engine At Idle
So, I have heard a little bit about the oil pump bolt issue. However, I am still confused. Was this issue fixed for the 2008 model and what are the symptoms? I changed out my valve cover last night due to a PCV valve failure. The car is running great except there is a slight rattling sound coming from the drivers side of the engine at idle. I know I left nothing around the car that could have gotten in the motor when the valve cover was off. This issue was not happening before changing the valve cover. What could be causing this noise, or is it typical for this motor?
View 3 RepliesFord Super Duty (1999-2016) :: 2004 F250 - Slight Hesitation When Trans Is Engaged And Tow Haul Light Blinks
I have a 2004 F250 Torqshift trans, 155,000 miles. It has had a slight hesitation when trans is engaged for about 4 years, not a problem the dealer has no fix they said.
Now today for the first time I had a tow haul light come on while driving on the freeway. It would not go into overdrive and the light keep blinking. Later in the day, I let it cool down and it drove fine to the store about 2 miles. When I got in to drive home it had tow haul light go blinking and check engine light came on this time.
I hooked up my code reader and it's giving codes: P0720, P0751 and P0766.
Should I take it to the Ford dealer, a Transmission shop or have a friend who worked at Ford Dealer do the Work? I see that some people have changed out the TFT sensor and corrected the problem. While the pan is down should I just have all the shift solenoid sensors changed?

I got an 800rpm rough idle, no serious lack of power, every time after filling up w/ gas she starts slowly (bout 3 secs) and then tries to die. she catches herself and revs from 400-1200 for about a minute, then drives away fine. Getting:

16825 - P0441 Evap ECS : Incorrect flow

Also have: 01039 - Coolant temp sensor(g2) : open or short to plus? (intermittent)
Doubt the last has anything to do with BIG problem, but my temp sensor on ly gets off 0 when i am moving and using A/C...is this going to cause issue now/later/ever?
