Accent MC (2006-11) :: 2009 - Misfire On Cylinder 3
I have a 2009 Accent. It has a misfire on cyl 3. I've changed the spark plugs... no change. I swapped around the coils... no change. The misfire stays on cyl 3. What are my next steps to isolate and resolve this misfire?

So recently my 2009 hyundai accent has been idling rough, and has been very sluggish when accelerating. Usually the rough idling is the worst when the car is first turned on and tends to tone down as the car keeps running. I had the codes red and I believe it was C0302 C0303 C0304, saying that cylinders 2-4 were misfiring.
I replaced the spark plugs which didn't fix the problem, although cylinder 4 did have a small amount of oil above the spark plug and a little bit more below the spark plug, I am not sure if that means anything useful or not. I don't have a way to check the coils directly but I swapped coil 2 with coil 1 and checked the codes again and it was still cylinders 2-4 misfiring, so I would imagine that means the coil isn't the problem. I then tried spraying WD-40 around the vacuum tubes, and if the intake manifold is on the back of the engine I tried spraying it around that gasket as well, but I didn't notice a change in the idle speed.
At this point I am not entirely sure how to proceed, from what I have read the issue causing a misfire would be either there isn't a spark, which seems unlikely at this point, or the mixture of fuel to air is wrong. That is the part I am unsure of how to diagnose/
Accent LC (2000-05) :: 2002 - Gear Grinding And Leaking Slave Cylinder
When changing gears my accent grinds as if its not engaging properly? I checked my slave cylinder and the rubber was filled with silver looking fluid could me replacing the S/C fix the issue? I don't think its synchro issue i tried double clutching and still no difference. the grind sounds the exact same as it does when you accidentally release your clutch when changing gears and it hasn't engaged properly. I also changed my manual gear box oil.

My car was shaking badly during idle and the Engine and VSC Off lights came on simultaneously. I took it to a local garage (not dealership) and they said that there is anti-freeze leaking into a cylinder. They said the only way to clean it out/fix it is to first remove the entire engine from the car so it could be worked on. It will cost a total of $2,700. My engine has 141,000 miles on it so they said this may be risky since it is so used. They said for $3,500 they could swap it with an engine that only has 31,000 miles on it (and a 6 month guarantee.) By numbers this sounds like a no brainer (I am assuming?) but I am curious if swapping the engines would be worth it seeing as the rest of the car has still traveled 141,000 miles. I have kept it in good condition and such though. I am also curious if the engine really does need to be removed to fix this sort of problem or it it could be done cheaper.

View 6 RepliesAccent MC (2006-11) :: 2007 - Cylinder 1 Misfire
I am currently having an issue with my 07 Accent misfiring on cylinder 1. So far, I have changed the spark plugs, which were due anyway, and checked the coil pack. Every coil on each cylinder reads 0.8 ohms, so I am going on the assumption that they are ok. Didn't see any issue with the connector end inside the boot. However, when I changed the plugs, I discovered that I had oil in the plug tubes on 1 and 4. So I changed the valve cover gasket and tube rings and cleaned all oil residue from the packs. I have also checked the short coil wire harness right on the packs themselves. Have not tried to check further because I don't know which pins that harness goes to on which ECM connector. I still have the misfire, and I'm not sure where to go next. I was thinking compression or fuel injector. I don't have a compression tester, and I assume the only way I can check the injector is to swap it with another cylinder?

My car has been really acting up lately (AGAIN) so I took it in to have it looked at and they came back and told me it had multiple cylinder misfire, and they wanted like $1200 to fix it. What in the world does that mean and what is entailed in fixing it? They mentioned doing a full maintenance on it.

Yesterday while driving my wifes check engine light came on and started flashing so she limped the car home so that i could take a look at it. I know from previous issues it was a sever cylinder misfire. I hooked up a computer to it and got codes for cylinder 1 &2 having misfires. So today i went and bought new plugs and 2 new ignition coil packs. when i took out the coil pack on cylinder 1 it was broken off and the top of the plug was broken. (nothing entered the cylinder and there wasn't any noticeable oil. But when i changed cylinder2's plug it was covered in oil... i changed the plug and coil pack and cleared the codes from the computer and started it. there was some blue smoke coming out the back (lots actually) for a min or 2 then went to regular exhaust. what would cause the oil in cylinder 2 and possibly 1?

Her 2008 Accent is leaking a thick oil from the top of the shocks. I noticed it when switching the summer wheels back on. The mileage is low at only 36000 Km/ 22500 Miles. Not a lot of use on them. I guess 8 years and the seals just can't seal no more. This car was well cared for since new.
The ride feels fine but I'll be looking for a sale on rear shocks.

My 2011 Accent's engine light came on recently. The mechanic said it was a cylinder 3 misfire and recommend changing the spark plug and coil pack for that cylinder. We did that over the weekend. Now the light is back on and has read 5 codes in the past 12 hours (4 at one time). They are P0303, P0304, P0003, P0403, and P0100. I have looked the codes up and can't discern if any could be caused by one main issue. About a month ago it read a code for the oxy sensor, but it went away and never came back.
View 3 RepliesAccent MC (2006-11) :: Misfiring Followed By CEL Coming On And A Cylinder Cutting Out
I'm having the absolute worst time trying to fix my wife's 09 accent. We bought the car in '12 with 45k miles on it, and just hit 109k last month. About a year ago, the car started misfiring badly (hot day, after reaching operating temperature) followed by the CEL coming on, and a cylinder cutting out. I (mistakenly) figured coils, and replaced them. This "fix" didn't last more than a couple months.
I've also replaced the intake manifold gasket, suspecting a vacuum issue, due to the symptoms. While doing that, I put in a new PCV valve. To no avail, as the car still misses, chugs and shudders while accelerating at operating temperature. I've disconnected/checked the sensors on the manifold, the 02 sensors, the evap purge solenoid...I absolutely can not wrap my head around this.
The weird part is that the car starts fine when cold, (with only a split-second hesitation if you goose the throttle) and will run great for about 10 minutes/until it warms up. Then,once it warms up it will jerk, shudder and not accelerate at all unless you knife the gas. After letting off the gas, it goes right back to "misfiring" and the light comes back on. I can shut the car off, restart it, and it will run fine until the accelerator is pressed.
Accent MC (2006-11) :: 2008 - Running Really Bad / Cylinder 1 Misfire
This morning my son started the 2008 Accent and it ran really bad, he shut if off started it again and still ran really bad and check engine light started to flash. Shut it off and ran for the bus to school.
Went and picked up a OBD scanner and found a cylinder 1 misfire. Tried to start it and had a really hard time and when it did start ran like crap and smelled gas. Checked the codes again and now got Multiple cylinder misfires, cylinder 4 misfire and cylinder 1 misfire.
Pulled the engine cover to pull the coils and plugs and I find a ton of mouse crap. No signs of any chewed wires or anything that I could see. Drove it to the local Hyundai dealer tonight because I am worried that it may not be the coil packs. Drove OK to the dealer. My brother is the service manager at the local Mazda dealer and he sees a lot of mouse damage. Said I should put a couple of old socks with moth balls in the engine compartment to deter the mice.
Accent MC (2006-11) :: Valve Cover Leaking?
Haven't had the engine cover off for about 25k now (cleaned it up under there last time I changed plugs.) Took it off today and noticed it's a little oily on all four sides around the valve cover.
Pretty sure I can account for the oil that's near the filler cap... I don't recall spilling enough that would completely go around the entire valve cover though...
But how did it end up so high on top of the valve cover on the corners? It's even a little wet looking on the back if you look hard enough..
I only have 4600 miles left of the 10/100 warranty so I'm glad I caught this and hope the dealer can do something about it... or are they going to tell me this a "normal" amount of seepage? I haven't owned a vehicle with plastic valve covers before so I don't quite know what to expect.

I have a 2010 accent GL manual sedan. It has 104,962 KM on it, the warranty expired December 18, 2015. Since February this car has become a frustrating money pit. Being in the dealership constantly for repairs, then within a week something else 'happens' and back it goes. Spent almost $5000 in 4 months on repairs. Decided that's enough and will do majority of repairs myself.
Yesterday while drive on the highway I had a sudden loss of power and a check engine light came on. My scanner which has become a standard item in my glove box indicated a misfire on cylinder 2 - P0302. I limped the car home, in 3rd gear I was having a hard time staying above 2000rpm at 60km/h. at lights I had to use hand brake so I could keep my foot on accelerator, revs were dropping below 300.
Today I replaced all the plugs (all 4 were still in good or better condition, #2 showed signs of a slightly rich burn and #3 a slightly lean burn), replaced all coil boots (no cracks, no burns, and still pliable), removed and cleaned all the injectors. Error code P0302 persists.
Accent MC (2006-11) :: 2008 - Code For Cylinder 1 Misfire / CEL Flashing
I have a 2008 Hyundai Accent that is giving me one heck of a headache. I keep getting a code for number 1 cylinder misfire. When you start it up it runs fine for a while then the CEL will flash and it will start running rough. As soon as I shut it off and restart it, it runs fine. I even experimented with it this morning on the way to work. It started running rough doing 60, I put it in neutral, turned the car off and then right back on, put it back in gear. It ran fine the rest of the way to work. I have swapped coil packs, fuel injectors, spark plugs, and have even hang tested another ECM. Still number 1 cylinder misfire.

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.
