Accent MC (2006-11) :: Misfire With Error Code P0302
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 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) :: Shaking And Idling Really Rough
I have a 2006 Hyundai Accent that won't start. My wife was driving home the other day, and while she was sitting at the light she said she noticed a sudden change in the idle. She said the car starting shaking a little and idling really rough. When she tried to accelerate after the light changed, she said the car sputtered and would barely go.
She was only a couple of blocks from the house so she continued home. The car made it the rest of the way home, but she said it never went over about 5 mph even though she was pressing the accelerator as she would if she were going about 30...the car just never responded. When she pulled into the garage the car died as she was turning. Now it will crank but it won't start at all.
I tested the crankshaft position sensor with my multimeter and it was bad. I bought a new one and put it on, and I tested it immediately. The new one works, so I plugged everything back in and tried to start the car...nothing, just cranks and won't start. It's getting fuel and fire as well (tested both), but it's not hitting on any of the cylinders.
Accent MC (2006-11) :: 2009 - Idling Rough / Cylinder 2 To 4 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 MC (2006-11) :: Code P0339 - Car Stalling While Idling
Twice today my car stalled out while idling. Once at a left turn red light and once in the drive thru. The first time it restarted after about 10 minutes. The second time it restarted after about 2 minutes.
Car is throwing cod P0339 for Crankshaft Position Sensor A Circuit Intermittent.
I did some reading up on this on the forums but didn't do much about it. I just tried wiggling the wiring and all that when idling, didn't notice any roughness or stalling so.... may not be a connector issue.
Anyhow, planning to take it in for diagnosis and repair as it's really not derivable the way it is.
Actually this is the first time ever the car has given me engine trouble of any kind. just passed 90,000 miles. Shucks, streak broken.
Ford 7.3L Power Stroke (1999-2003) :: Code P1316 Thrown When Engine Is Cold?
I keep getting my SES light coming on in the morning when my engine is cold. I'm getting code p0603 and p1316. I was told the first one is just from using my tuner. The second code is the injector driver module, just trying to figure out what is causing it to throw the SES light only when cold.

My girlfriends 2007 accent as thrown codes p0300 and p0302.
After reading everything I could find, I had coil pack on my list of possible problem items.
The car sat in the driveway yesterday and when she went to start it today, she couldn't get it to.
I got it to start when I got home by giving it some gas while turning the key, but I don't want to drive it anywhere.
The hard start is leading me to believe it's the coil pack.
I was going to start with changing the pcv, spark plugs, and run fuel injector cleaner through it because those are the cheap possibilities...but now may add in a new coil pack.

View 7 RepliesAccent MC (2006-11) :: Stalls When Idling - No Check Engine Light
So, I have a 2011 Hyundai Accent. It drives great. Until recently.
My wife noticed that it was cranking a little longer than usual before starting. Then, one day, I noticed it. So, I stopped the car and restarted it to see if it would happen again, and listen more closely. But, all ti did was crank.
I became upset and went in to do some research and make some phone calls. I came back out and voila, it magically worked fine again. Weird, I thought.
A few days later, no incidents. We go to the grocery store. On our way out, it cranks longer. This time I'm not going to restart it, I think. So, I start driving and everything is great. Except...it suddenly wasn't accelerating. It felt like it was in neutral for like 100 feet or so, then back to normal. We're making plans to take it into the shop at this point.
The next day, we go out to get coffee. Car drives great. On our way out, no problems. We stop at the red light, and it stalls. I have to push it into a parking lot and call the tow. Strangely enough, it starts again ten minutes later, and runs fine.
The stalling and being unable to start for tenish minutes phenomenon has happened three times.
We took it to the shop, it actually did this as I was filling up gas--stalled. I pushed it into a space and waited a few minutes, bam, it started up fine. The mechanic told me that the engine light had been reset. He couldn't figure it out. Said everything looked great.
So, the run down is this:
-My car stalls when idling, but only after it has been driven some, stopped, and restarted without a lot of time passing--like when you're coming home from the store or something, after it sits for 30 or 40 minutes.
-Once stalled, it will not restart again until a few minutes have passed --something like five to ten minutes.
-There is no check engine light. Fluid levels are good. Connections and whatnot, according to the mechanic, looked good.
-When it stalls, all the electronics stay on and work. The oil light and engine light pop up (like this key is in and turned part way), then it all goes away when the car restarts.
-the computer says that it was reset after it does this.
Accent MC (2006-11) :: 2010 - Code P0303 And Rough Idle After Filling Up
I just bought a 2010 Accent for my daughter and this was the 2nd time I filled it up. I realize now I should not have topped it off all the way but I did. The tank was probably bone dry when I filled it up as well. Within 5 miles after I filled it up, it started running rough and the check engine light came on. I stopped it and checked around under the hood. Checked to make sure the gas cap was tight. I drove it again and it appeared to run fine. I stopped by an Autozone and had the code checked. It was a misfire code for cylinder 3.
Drove it home (10 miles) and parked it. I took the battery terminal off and cleared the CEL. When my wife drove it a few minutes later, the CEL came on again and it started running rough. Had the code checked again and the cylinder 3 code came back. The guy at Autozone said over-filling the tank when it was empty probably caused too much pressure on the fuel going into cylinder 3 and that it should correct itself in the next few days. I drove it 20 miles to work today without any problems. It seemed like it had to be related to filling up the tank since it happened a few minutes later.
Accent MC (2006-11) :: 2009 - Running Rough At Idle And Would Crank Hard / P0496 Code
Check engine light had come on, the car was running rough at idle and it would crank hard. So I threw my code scanner on it only to find out it wouldn't link. Drove it to O'Riley's and had them pull the codes. It ran rough and had next to no power on the way there. O'Riley's pulled the codes and we got a P0300 (random multiple misfire), P0301 (cylinder 1 misfire), P0302 (cylinder 2 misfire), and a P0496 (EVAP emissions system high purge flow). So once I got it back to the house, she told me that she had the codes pulled once before and that they told her it could be her gas cap so she replaced it. She also stated that she had replaced the plugs about 3 months ago.
So with new gas cap and new plugs, and these codes, I did a bit of research and come to the conclusion that it'd replace the purge solenoid. The solenoid was making a pretty loud ticking noise and when I pulled it off, it rattled so I figured that was the fix. Pulled her plugs and you can clearly see that cylinder 1 was running VERY lean and cylinder 2 was a little richer but still too lean. Plugged the plugs back into coils and laid them on exhausted. Turned the car over and we had spark. Lead me to think the misfire had something to do with the P0496 EVAP code. Put everything back together and erased the codes. Gave the car back to her and told her to let me know if the light came back on. That was Wednesday last week. Sunday she told me the light came back on and the only code that came up was the P0496 again. When I gave it back to heron Wednesday, it would still crank hard but would start.
Battery is new and checked good, alternator is pulling about 14v and checked good and the starter checked good. My dilemma is the code and the hard crank. She told me that it only cranked hard for her once so I am assuming that has gone away but we're still left with the P0496. I am not 100% sure as to how this system operates but I understand it for the most part. She told me that she had just put gas in it before the light came on. Not sure how much time had elapsed after filling it and the light coming on but I do know she put gas in it. If it's a high purge flow, that makes me think there may be a leak in the system but I'm not sure where to go from here without throwing a bunch of parts and money at it.
Camry :: 2 Ignition Coil Failure - Engine Code P0302
Just a few weeks ago I replaced a bad ignition coil because I got the engine code P0302. I replaced the spark plugs with NGK Laser Iridium and the second Ignition coil. Now a few weeks later the Ignition coil 1 has died on me.

I recently had my "Service Engine Light" come on, Sunday to be exact. I went through my normal procedure of checking the fuel cap and drove several times to no avail. So today I ran by Autozone where I got the P0302 code. Now I realize I could go in for a tune up, but I'm a college student and just spent all my money on books so I'm looking for some DIY solutions before I lay down any large amounts of money. Where to start. As for a bit more background, I filled my car up with gas on Friday, the light came on Sunday and the car will shake on initial idle of the car.
View 6 RepliesSanta FE SM (2001-06) :: Engine Light Come On With Code P0302 Cylinder 2 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?
View 1 RepliesSanta FE SM (2001-06) :: Engine Having Hiccups When Accelerating - Code P0302 / Misfire On Cylinder 2
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?

2007 Accent Hatchback. Put gas in it from an Exxon we have bought from before with no problems. My kids car, running on vapors, put 1/2 tank of gas in. Pulled out of gas station and car starts running really rough, shaking. Still running though. I have gathered some knowledge from other threads, like timing belt needs to be changed (65000 on car). I replaced the plugs as an initial attempt at correcting the problem. Runs better, not great. Saw a thread with changing to better gas, will try that.

Check engine light came on. Codes are P0300, P0302, P0304. Plugs were previously changed. Plugs look good. Changed both coils. Light still one. Injectors also previously cleaned. What else should we check for? Valves hanging? Anything else to check for?
