I've been having a curious issue with the engine in the Passat. When I put gas in the car, it generally is hard to start and stalls. This happens once or twice, and then the car runs great. Sometimes the check engine light will come on, but I haven't been able to read the codes. The mechanic said that the car was driveable. I am curious for potential causes and solutions?
View 4 RepliesSo maybe it is just my incompetence on this.... however, I was putting my second tank of gas in the 2016 and the Fuel Filler door will not shut...
Not only that but since the door will not shut, on my dash screen it keeps saying "Refill Ready" every 5-10 seconds.
I have an '88 EXP Escort with the non-HO 1.9L
I was noticing a rough idle (vibrating, sounded like it was bogging down)
I changed the plugs, wires, cap and rotor. Still happening.
Noticed that my o2 sensor was unplugged. Plugged it back in. Still happening.
Went to check the air filter and noticed the insane amount of fuel that was coming from my injector.
I am getting horrible gas mileage (8-12mpg)
Here is a video of what I am seeing: [URL] ....
What would be causing that much fuel to be sent out?
Yesterday I started up my Phaeton after it had been sitting for about almost a week. When it turned over it had a rough idle and also a fuel smell, as I drove it the idle went away. However I have never had this happen before and the fuel smell concerned me.
View 4 RepliesOk new issue that started yesterday only get it at idle. Runs great above idle no real power loss or change in fuel econ. Haven't really had a chance to test much. I was thinking maybe a injector issue but I don't know
View 14 RepliesI head out to work this morning and truck drive fine. I do not get on it. I cruised on the highway for 12 miles at 70 mph. I get to a traffic light and then it begins to idle rough and my fuel pressure gauge reads 0. I replace both filters over a month ago and did the blue spring upgrade at the same time. I've put over 2000 miles on the truck since then without issues until this morning. Also the fuel pump was replaced by the dealer a year ago in July. No check engine codes. Where do I start looking?
View 13 RepliesMy new 2015 Sonata 2.0Twith 8000 miles started running oddly about 2 weeks ago. Rough idle with engine "sputtering". Erratic acceleration -- merging into traffic on highway and car not going over 40mph, even with gas pedal all the way to the floor. On deceleration, clunky down-shifting. Very hard to drive. Dealership first came back with diagnosis of "buildup on throttle plate" (Note - I use only high-quality gas AND only have 8000 miles on car, 3500 or that being one long highway road trip). Then, after 3 days of diagnosis, they say I need 2 new fuel injectors I am baffled how a new car can have either buildup or failed fuel injectors...
View 13 RepliesI have been experiencing some issues with my '06 rio5 (same engine as your hyundais). this forum is way more active than the kia forums, so figured id give it a shot here.
I am experiencing a rough idle at start up while the car is low on fuel (<1/4 tank). it idles rough for a few seconds, the check engine light flashes a bit, and then it runs fine.
The car is an '06 rio5 with approx 19k miles on it, five speed manual. Also, sometimes after refueling and it will just shut off while waiting at an intersection. Not sure whether these two issues are related, but thought i would mention it just in case they were.

Having a rough idle on a cold start. After some research and closer inspection of the vehicle, I'm quite certain I have at least one leaking injector that is flooding a cylinder and causing the car to misfire on a cold start. I'm also not at the gas mileage I should be at.
So I'm wondering, is fuel injector replacement as straightforward of a job as it looks? Any major issues I could run into in doing a replacement?
I'm planning on replacing all six injectors (I can get them for $50 each buying online with a discount code), but given that the vehicle is so old am I better off just replacing the faulty ones? I'm assuming pulling the spark plugs and seeing which cylinder is wet will tell me which I need to replace.
And one more question: Is there a way to depressurize the fuel system when I park the car for the night, thus preventing fuel (or most of it) from leaking into the engine until I get this fixed? I've read that just unscrewing the gas cap can depressurize the system.
I just replaced fuel pump and tps on my 1989 Dodge Dakota 4 cyl truck. Now it idles rough and the check engine light came on. I have removed battery cable to reset computer but did no good. What could be the problem now? I have since replaced the plug wires and distrib cap and it is flashing 3 5 5 twice now?

View 13 Replies2004 f150 fx4 w/ 5.4 .I have a code that read " system adaptive fuel to lean bank 1 " and the same for bank two. So, I got on here and did some research. Cleaned the throttle body, maf sensor, air filter, looked for vacuum leaks, changed the fuel filter and it still is running very poor at idle and it seems to be getting progressively worse...
View 2 RepliesI bought a 1999 f350 v10 about a month ago took it on a 1200 mile trip from Arizona to Kansas. Truck ran great till I got Kansas. The truck started to lope after I got fuel at a fuel station. Did not get any check engine light on. I check for vacuum leaks did not find any. I change all the coil packs, spark plugs, IAC valve and fuel filter. Clean the intake and put sea foam in the fuel tank and the truck still idles rough. Change the egr vavle. Truck ran great till I got 10 miles down the road then the truck started to lope again. So I'm getting really frustrated over this truck.
View 4 RepliesIt happens in the morning or on cold starts. The car has a rough idle and the throttle response is terrible. Its very sensitive and jerky. Could this be bad spark plugs? Its a 2006 2.0T and its had all the maintenance done.
View 5 RepliesI have a B5 99.5 AEB and having rough idling. Started the car in the morning seem fine. Later that evening started up again in a warm up idle and then the car shut off. Tried starting up again but took couple of minutes. Pumped the gas piddle started up but looking at the idle gauge needle was bouncing around. I don't think i have an vacuum leak.
View 2 RepliesI 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:
17544 - P1136 Bank 1 : System too lean
16825 - P0441 Evap ECS : Incorrect flow
16684 - Random/Multiple cyl misfire detected (intermittent)
16688 - Cylinder 4 : Misfire detected (intermittent)
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?
I drove home Saturday morning from work with no issues. Car sat until Monday night and as soon as I had to stop at a light it was idling very rough where the rpms were jumping 3-400 up and down. I make it to work and on the way home I experienced the same idling issue along with some misfiring. I scanned and came up with the following codes. I have no CEL. I had my APR flash, Forge Intake, Turbo back exhaust all installed 2 and a half years ago. I have owned the car for four years never having replaced the DV or PCV. 87,000 miles.

My 1.8t is very rough at idle when cold, smooths out when over 1000 rpm and when at normal operating temperature. Code reader says 171 and misfires.
View 6 RepliesI recently purchased an 06 f150 fx4 5.4L with 60K miles. Just recently my check engine light came on and I've noticed a slight rough idle in park. I took it to autozone and the code read P0422 evap emission leak. Bought a new fuel cap but didn't work... EGR valve?
View 2 RepliesMy car started a rough idle last night.... Pull to stop light, in gear, a/c on #1 and car shudders and acts like it's going to stall..... Went away as I drove a round a bit.....back this a.m. (after the warm up program ran) drove it a bit and was sporadic.....and even went away...then came back.....
Its worse when car is at stop and in 'D'.....little better with a/c off and/or in neutral......it finally threw the CEL today....... I had the fuel pump recall done about a month or two ago, car has 36k+ on it...... Anything I should have the service dept look for aside from what the fault codes might read?
[URL] .....
Idles ok in park and neutral. Gets worse while in gear. Car has high miles around 160.000. Fuel injection flush? Fuel Filter? Vacuum leak, and where to look first? No check engine light, no misfire codes just a rough idle when in gear.
