Accent MC (2006-11) :: 2010 GL - Misfire On Cylinder 2 / Code P0302
Jul 30, 2016
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.

2009 Accent, 1.6L 154,xxx Cylinder two misfire. Engine was rebuilt due to timing belt. Twice. Second time I did it. Replaced plugs, coil packs, all gaskets, (everything new in the head) did a smoke test, compression test 180 psi across all four, used a noid light for coil packs (good) did it at the injectors 1,3,4 did good, but 2 came on then went off. Check resistance and it shows good, replaced injector anyway and the connecter. Still doesn't work. Checked powers and grounds at the rail, good. Good solid voltage. I hooked up a scan tool and tried to shut injector 2 off, no change in RPM or vibration. Scan tool worked for 1,3,4. Used another PCM, still misfire in two. Even jumped a wire from PCM control and 15A inj fuse for the 12V constant (bypassed the harness) and still doesn't work. Also have knock sensor code, just two codes.

I just purchased a 2005 Santa Fe, 4WD, 2.7l..the engine has a miss...the code that came up was "misfire in #2 cylinder"..I checked the coil pack...and the wire harness just crumbled..so I replaced the coil pack...reset the code..and it was good for a couple of days...I got through inspection...today I put on the A/C..and the engine got rough..the check engine light came back on..same code..misfire in #2..I'm thinking the injector or what else could it be? plug? wire?

I have a 2002 Santa Fe 4 cyl that is giving me a problem that I could use some advice on tracking down & fixing . First & most important is a code P0302 # 2 Cyl misfire. How to check the ignition coil pack , injector ,& wire for this cylinder in home garage with normal tools & meter . Is there a you tube displaying how to do this step by step ?
The other problem which I don't have the code for at this time is that some part of the exhaust is not getting warm enough & this also put's the check engine light on . Will get back on this one when I solve the main problem Misfire.

I have a 2005 Santa Fe with the 3.5 with 112000 miles on it. I had the engine light come on with the code P0302 cyl #2 misfire, I got spark plugs, plug wires to do a tune up on it. I changed all of it and got it back together, started it up and it still had a miss to it. I then took the front spark plugs out and did a compression test on it. #2 was at 85, #4 was at 120, and #6 was at 160. I couldn't check the back cyls because I had already put the intake back on. I then did a wet test, and all the cyls came up to 160. So this tell me that the piston rings are bad in #2 and going bad in #4. I have kept all the oil changes up and up to this point I haven't had any trouble with it. Having this problem with there 3.5?

Getting error code p0302, misfire in 2, pulled the plug and had oil on the treads and on the lower part. My guess is the valve cover gasket, but I'm not 100 percent sure.

2005 3.5L FWD. 5 days ago I left the house, the engine was running smooth at idle but having hiccups when accelerating. Check engine light went on when accelerating but going off at idle. Turned around at the first stop light, parked the car home and pulled code P0302 misfire on #2 . Figured it's most likely the coil, was going to order one next day but to my surprise, no more check engine light next day and engine has been running smooth since then. Probably drove 100 miles since with no issues. I have 6 spark plugs waiting to be replaced but it's too cold to do it right now unless it's an emergency. Car has 105k miles now, spark plugs were changed at 63k. Was this just a fluke and P0302 will probably not come back or should I not risk it and just go ahead and replace the coil? If I end up replacing the coil, should I do one coil or all three?

I have a 1995 ford ranger 2.3 L dual coil packs new plugs, wires, coil packs, tps, idle air sensor, internal temp sensor, and a replaced mass air flow sensor from wrecker. That all said my one son missed a plug when i replaced it , it had no tip left on it , but since then i now have a misfire in cylinder 2 where the olther plug was found and replaced ...
Gap for plugs are .44
Used the wrecker maf to see if it would clear a p0113 which it did. I am stumped on why at approx. 30 minutes of driving that the cel will flash then set a p0302, no other codes no fuel smell. rechecked plugs all are clean haven't been able to check fuel pressure yet, and i out a can of seafoam in the tank to see if it clear out injectors.
Besides all, I will check injector to see if I hear anything but I'm stumped. Also we have to have an emission test so is it best to fail the test and will it show me what I'm missing.

Check engine code (P0302). I have a 2007 GS 350 with 116k miles that was driving perfect until this week. My check engine light was initially blinking but is now on solid along with the check VSC light. My question is: of the 6 cylinders (3 on the left and 3 on the right when facing the engine) which one is cylinder 2?

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.

So I bought my accent used a couple months ago. It is a 2007 SE 3dr 5spd manual. It ran nice during my test drive and the price was right so I bought it.
Now I'm wondering if there is any way to find out the service history on the car...at least the major one's (30k, 60k)?
I ask because recently the engine was idling a little rough and it threw a P0302 code so I changed the spark plugs and holy-cruddy-deposits-batman those things were black. Gapped the new ones and popped them in and its a noticeable difference. My CEL keeps coming on and throwing a P0496 code as well, virtually once every tank of gas. Its not the gas cap so my next step there is to check the PCSV and hoses.
With these little problems, it makes me wonder about any larger issues. I know the timing belt on these things is supposed to be replaced at 60k. Additionally I would be willing to bet that my ECM software is out of date. Would Hyundai have records for any of the big maintenance milestones since they are required for warranty work?
How much does it cost to have a dealer check your ECM software and update it if needed?

I have a 2010 model Hyundai Accent showing error codes P0301, P0302. It has a 1.6L engine. I know little about cars, what is going on and how to fix it.

I have a 2002 Camry, 2.4 with 155k miles.
This morning I was going to work and was making a lane change and hit the accelerator quite aggressively. Suddenly my engine started to run really rough and shook the car and the check engine light started flashing.
I checked the engine code and its giving me a P0302 Cylinder 2 Misfire warning.
I have read that there can be various reasons but I figured since this problem is consistent its not a vacuum issue? Could it just be a bad plug? I don't have the tools to fix it, I am going to get them soon to pull the plugs and inspect then, and will replace them anyway since I don't think they have ever been replaced.

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.

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?

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.
