Accent MC (2006-11) :: Misfire On 2 Cylinders - Location Of MAF Sensor?
I have a 2009 Hyundai accent. 2 cylinders misfire. I changed out the spark plugs after the misfiring began and the 2 cylinders that misfire don't follow any specific ignition coil, it's just 2 random ones.
Looking at the data with a reader points to fuel injector number 1 not working properly. The first few seconds the car is on the check engine light blinks and fuel injector 1 spray duration (fluctuates based on gas applied) changes just like all the others. However, when the check engine light goes solid (then the misfire code is thrown) fuel injector 1's spray duration is stuck (usually around 3.5 ms)
The cable going into the fuel injector powers those little troubleshooting lights like it should until you plug the cable into the fuel injector OR remove and replace the light a few times.
I don't know much about cars but someone told me to try cleaning out the Mass AirFlow sensor as they had the problem above and the MAF sensor was the cause. I can't find anything on where the MAF sensor is located though.
Accent MC (2006-11) :: Low Acceleration And Engine Shaking / Two Cylinders Misfiring
So as I was heading out the other day, the car had low acceleration and engine shaking. The check engine light started flashing.
Checked the codes at the parts store: P0300, P0301, P0303.
I just dropped it off at the auto repair shop.
Could it be a I'm just wondering if I shouldn't have taken it to the dealer as the printout says it could be a CPU issue?
Accent MC (2006-11) :: 2008 GS - Misfire On 3 Cylinders / Rough Idle And Poor Acceleration
After scouring through hundreds of threads on this forum (which is Awesome, BTW), it seems as if this misfire / rough idle thing is fairly common (which is scary!!). CEL is on steady. Had the codes pulled; P0301, P0302, P0303. At the recommendation of the mechanic, I had the plugs replaced...no improvement. He then replaced the ignition coils...no improvement. Just finished replacing the MAP sensor. This actually had a VERY temporary positive effect. However, after about 5 miles of driving, the misfiring returned. Took the car to the Hyundai dealership, and they acted as if they didn't want to fool with it. They referred me to a couple of local repair shops...????

Daughter got a new car 2010 accent gls. It burps fuel after every fill up (after the fuel nozzle shuts off like it should) and runs down the side of the car... sounds like hyundai has problems with this on a few different models. This is the first non-gm vehicle in our family. I grew up working with them and driving them and know them well.
Anyway, looks like 3 different parts here:
Having this same issue on my daughters 2010 Accent GLS. It burps up fuel after the fuel shuts off on the pump. Which exact part do I need?
-Vapor Canister
-Vapor Canister Purge Valve / Solenoid
-Vapor Canister Vent Valve / Solenoid
I'm assuming it's the vent valve solenoid, I've got the part on order. Looks easy to replace and I will be pulling the canister box down and taking a look when I replace it. I'll check everything with air (blowing into it etc...).
On a side note, combined fuel economy is 36.5mpg. I would expect that though, small engine, small car etc...
Accent MC (2006-11) :: Hard To Start When Have Low Fuel
My car has a bit of trouble starting every now and again. I have noticed it is when I have low fuel. When I try to start it it will just keep winding over. I'll switch my car off completely and try again. It usually starts the second or third time. What could be the problem? Its a 05/06 Hyundai Accent

Have an Accent 2006 manual drive. Had this problem 3 times after considerable gaps.
First time, driving normally during the day, stopped for fuel. Switched off ignition, filled up, then suddenly did not start. Turned over but did not start. About after 3 minutes of trying (sometimes continuously and sometimes keeping a short break), started normally and I was off. No error/warning light, etc. Nothing. Did not mention to the service center during regular servicing as thought it was a one off incident.
Second time, several months after first incident, a warm and sunny day, went for a pollution test. Parked to wait. Was called for the test. Started and went over, completed and parked again to wait for the certificate. Got it in about 15 minutes. Then again, turned over normally but did not start. This time, battery died after several tries. So I had some people push and it started first time and I carried on. No error/warning light, etc. Nothing.
Third time, about 2 months from the second incident, was driving normally in the early evening with no issues during the morning/day. Slowed down at a pothole in the road, and the engine just died. Turned over normally but did not start despite several tries. So while preserving the battery, I had some people push the car confident as in the second time that the car would start. But did not even after several tries. So while pondering what to do at the side of the road, after about 10 minutes, gave it another shot. Turned over and started normally on first try as if nothing had happened. No error/warning light, etc. Nothing.
Has been about a month since, no problems. Just takes a wee bit longer than usual to start.
Accent MC (2006-11) :: Fuel / Gas Cap Loose And Throwing CEL Regarding Emissions
Twice now I've had my fuel cap/gas cap come loose and throw a CEL regarding emissions. This is fixed by screwing the cap back on and clearing the code. There is no good reason for the fuel cap to unscrew itself so I'm thinking there could be an underlying issue, possibly pressure related.

View 3 RepliesAccent MC (2006-11) :: Air Bubbling Up Through The Fuel - Tank Is Pressurized
I drive a 2006 Accent. A few days ago the code 0496 popped up for evap system issues. The fuel tank is pressurized quite a bit and with the filler cap off you can hear air bubbling up through the fuel. Sounds like blowing air through a straw into a drink. It is constant and putting the cap back on it re-pressurizes quickly. I have never seen this before in any vehicle.

My 07 has difficulty starting, only after adding fuel, or a fill up. I thought at first it was due to over filling, but it occurs after adding any amount of fuel. If I leave the car running while attempting to fill up, it sputters and dies. I have to press the gas pedal to the floor to start it, and it sputters for a few minutes, then runs fine, and starts fine until fuel is added once again. I searched and found where the General mentions a Vapor hose, but could not find more.

Make: Hyundai
Model: Accent
Year: 2007
Mileage: 70K
I've added Mystery Oil into my gas tank to clean fuel injectors as a maintenance precaution. I added it to a full tank of gas, when the gas tank was on low and I needed to get more gas, the check engine light came on.
The car was diagnosed with CEL reader from Autozone, misfire in cyl 3 is what the guy said. 3 full gas tanks later, it still has the same code and the car idles rough, hesitates and only seems to behave normal under medium to full throttle at higher RPMs.
I've been reading online for similar issues, as well as asking my friend who works as a mechanic at a dealership. Everyone seems to be accepting this behavior as normal and suggesting to wait out a couple of more gas tanks for the fuel injector cleaner to burn through.
I've looked at the spark plugs. 1,2, and 4 cylinder spark plugs have normal wear and tear. #3 has black build up, which corresponds with online pictures of rich mixture misfire.
I'm looking for a repair manual on another thread on this forum so I can take the injector from cylinder #3 out and look at it.
Accent MC (2006-11) :: 2009 - No Restart While Warm
OK all sensors and evac valve done. No codes being pulled. No check engine light. Car starts no problem in the morning or when its been sitting but when the car has been driven to temp. I will not restart and just keeps cranking, if it starts to start it shudders and dies. I am the original owner and its had any maintenance its needed.
View 4 RepliesAccent MC (2006-11) :: 2009 Starting But Not Turning Over
My hyundai accent has been giving me fits for about 6 months but I didnt think it was a major issue, apparently I am wrong. When it first started the check engine light would come on randomly and go off after a few minutes or even a day. Then it started staying on longer and when it would go off my car would stall. Then when it got cold twice I went out to warm my car before I left and when I came back out to leave it was dead, had to be jump started and while driving the first couple of miles it would die, it always cranked fine but it at lights or stop signs would die. Now it has stopped all together, it turns but wont start. I have a spark and we have tried the cam sensor and crankshaft. The fuel pump wouldn't go out while I was driving would it? or what could it be we are kind of at a loss.

2009 Accent GL Sport manual transmission. Battery keeps dying. 2 batteries over the last 9 months. This is on my son's car. Replaced battery and a few months later it's dead again. Had the system checked no drains on the battery, alternator work great. No fathom drains in the system. The car can set for a week before being driven. The only thing we can think of, because it's not driven every day, the little battery drains out by the systems in the car(clock, etc.). we think there's a .8 amp drain or less.

My wife and i have an 07 accent 2 door and we have a very hard time starting the car after putting fuel in it. Tank level doesn't seem to affect this issue. The car has 160,000 km on it. I've replaced the coil packs already twice. After getting the car to start after putting fuel in it it struggles at idle for the first 15-30 sec and then bang problem is gone until the next time i put fuel in it.
View 2 RepliesAccent MC (2006-11) :: Car Surged Once Like It Was Running Out Of Fuel Then Tachometer Stopped Functioning
I have a 2010 Accent GLS with 96,000 miles. Up to now I have only needed to do regular maintenance (which I do myself usually ) and had no major issues other than the sway bar drop link problem which I found the solution to on this forum. And self destructing spark plugs (on 3 separate occasions).
The other day while driving, the car surged once like it was running out of fuel. Then the tachometer stopped functioning. And if I floored the accelerator to cause a downshift I would lose power and the car would surge until I let up on the accelerator and the car would up shift. The CEL came on and I had the code read. It was P0339. So I replace the crankshaft sensor and everything went back to normal and the CEL went off. Until 2 days later...
Today the CEL came back on. I had no issues while driving as far as I could tell. I had the code read again and it came up as P0336, P0300, P0302, and P0303. The odd thing is I have no starting or running issues. So I'm really not sure what is going on here.

After getting to about 1/4 tank, I fuel up and fill the tank but when I try to start the car, it cranks for a while and then finally starts. It will idle really low so I have to rev it until the engine starts getting gas at a steady pace.
