Accent MC (2006-11) :: Engine Struggle And Stumble - Stuck Ignition Coil
May 22, 2014
My wife has an 09 Accent and a couple of days ago we were exiting the highway. As I stepped on the accelerator I noticed the engine struggle and stumble followed by the flashing MEL. I pulled into a parking lot and shut the car off and plugged the reader in to get the code but the computer already erased the code and the MEL light was extinguished and it ran fine the rest of the day. The following day my wife was driving it on the highway when the MEL light came back on but there was no associated engine roughness. I had her plug in the reader to get the code for me and it came up with P302 - misfire detected in the #2 cylinder. She didn't notice any engine roughness so I told her to drive to work but stay off the highway. She went out at lunch and the MEL light was off.
I did some research on here and the web and found the accent is known for going through ignition coils as well as a possible design flaw with the ignition wire harness that could cause it to rub and become frayed. I ordered the wire harness from our local Hyundai dealer and got an ignition coil from autozone. I also figured that I might as well get 4 spark plugs and replace them while I was at it. I got the plastic cover off and removed the 10mm bolt from the #2 ignition coil but it was wedged in there and would not budge. The coils from 1, 3, and 4 popped out with no issues. I ended up using almost a half a can of PB Blaster and 2 hours before the coil finally came out. The problem that I'm now looking at is some of the plastic from the coil remained stuck to the metal in the holder. Is there anything that I can use to clean out that metal cylinder?
After examining the spark plug from the #2 cylinder I could tell it was fouled and needed replacing but my concern is now that that new coil will get stuck in much the same manner. I'm pretty sure that the coils were WELL past due for replacement as I'm not sure when they, with the spark plugs, were replaced last. I'm pretty sure it was before my wife and I got together so that's more than the recommended 60k replacement intervals. I've ordered 3 more ignition coils to replace all of them and reset the 60k replacement interval. Since I replaced the one coil and 4 spark plugs the problem seems to have been corrected and the car is running great.

Ignition coils on Hyundai Accent (2011) getting stuck in suction? Or looking for engine vacuum pathway explanation?
I previously (~6 months ago) replaced one ignition coil that had a misfire. I currently have a check engine light with "No Codes" on code reader. My engine is rough idling with very weak acceleration. This occurred when trying to accelerate up a hill. I was looking to inspect the coil resistance and noticed the replaced coil has a pretty strong suction holding it in.

How to remove the clip on ignition coil connector wires that attach to all 4 of the coils.
I see that it has a black tab that you pull to the up or out position. From there I'm at a loss what to do. I managed to prode and poke and got one off, but I nearly pulled the connector off the wire and I know I didn't do it right.
Is there a simple way to release these mothers that I'm just not getting? If so, looking for explicit instructions in minute detail..

SO I was working on changing my spark plugs on my 66k 10; corolla. I was trying to remove the bolt(holds the cooldown), at first it was hard to wedge it, but slowly I was able to loose it up little by little. ALL the sudden the bolt made a snap noise, half of the bolt(head) came out with the ignition coil, the other half is still stuck in the whole.
I didn't attempt to change the spark plug or work on the other cylinder heads thinking all the bolts may snap off that holds the coil down. I drove my car around and the coil didn't move at all.

My 2011 stick shift no air Accent has a hesitation or stumble on light acceleration that comes and goes. It may not occur for weeks then re-occurs. It is hard to reproduce intentionally. It never occurs in cruise. The CEL is not on. Most often occurs at 1400 to 1500 rpm with slight acceleration or a slight increase in load as coming to a slight hill. I tried injector cleaner a few times and changed air filter. It seemed more reloaded to induction airflow so I changed the MAP sensor. I understand the 2011 Accent does not have a MAF sensor. It is still occurring. It is fine in steady cruise as well as in hard acceleration. I am wondering if it is a TPS sensor problem. It has 60,000 miles and otherwise runs fine.

09' Auto accent developed an issue that I haven't been able to sort out. Car began experiencing a condition where it was harder and harder to start, over about a 2 day period. As well, when stopped at a light it would idle fine, but almost stall when you tried to accelerate. Once above about 2k rpms it was fine, but then near 4k rpm it felt dead, didn't want to pull.
Only code was P0171.
Here is what I have checked thus far.
All injectors ohm out exactly at 15.1
-Fuel pump primes at key on like it should
-Verified cam/crank are timed properly (timing belt didn't slip a tooth)
-Car is MAP based, so no MAF to deal with. It's totally stock down to the paper air filter.
-Purge solenoid is closed and appears to be functioning properly.
I was checking things last night and this time it didn't want to start at all. I haven't checked for injector pulse or spark (it's coil on plug), but this didn't seem like part of the issue it was experiencing. Almost feels like a cam or crank sensor going out (timing is acting weird). Is there a relatively easy way to test the cam or crank sensors other than just trying new ones?

I have a question regarding oil burning by the 2GR-FE V6. My avalon is a 2006 xls/navi, 160 000 km, very well maintained, only synthetic oil changes (AMSOL 5w-30, but switching to 10w-30 now that the oil burning began). All the recalls were done on it already, it was dealer maintained till 65k then I took over when we bought the car. The only other issue I had with it were the 3 consecutive ignition coil failures (by the way, you must replace those with oem toyota parts, I tried saving money on aftermarket and the results were discouraging).

completely stock 2006 4.6, 230,000 miles, I purchased and can vouch for everything after 106,000.
Two separate issues...have had a slight ticking noise growing for about the last two years. Seems to get slightly worse near an oil change but that could be my imagination. It has finally gotten loud enough that my wife (who drives with the delicacy and observational skills of a Sherman tank driver) actually mentioned it to me the other day. It is directly related to engine speed whether the truck is in gear or not. I kind of think it might be a manifold gasket going out but am not sure. Am not very worried about it but...felt like I needed to mention it because of my bigger problem....
Truck has gotten very "cranky" on startup in the last week. Has a rough time finding an idle speed but typically sorts itself out after about 5-10 seconds. This afternoon it started idling rough at a stoplight. It got steadily worse and noticeable even at speed. Four stoplights and nine miles later it threw a code and coincidentally, I was in front of an Advance Auto. They read it and said the #3 cylinder was not firing. I bought an ignition coil, drove 15 miles home and changed it. From everywhere I looked online, this is the second cylinder from the firewall on the passenger side.
Had a little trouble getting it in and am not entirely sure it is fully seated in the slot, but I can't get it to go any further. Seems as tight as a couple of the others. I disconnected the battery to clear the codes, cranked it up and it seems to run "better", but still has a rough idle. Just test drove it about 12 miles and no check engine light but the idle has not cleared up. I think coil must be working fine because I have no issues at highway speed. Earlier, when I backed off the gas you would feel the miss very badly, but not as much when under a load.

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.

My 2004 Accent is stuck in the "lock" position in the ignition, and the wheel is locked and barely turns in either direction. I know this is supposed to be an anti-theft feature and I've tried all of the solutions listed here...
Turning the wheel hard and soft in either direction while holding the brake all the way down and trying to turn the key. Putting the car in neutral and then park and trying the above Disconnecting the battery for a few minutes and trying the above Jacking the car up on one side to release the tension on the pin.
My question is can I remove the spring at the bottom of the locking pin by drilling a hole in the center of the plate? I've seen a few youtube videos of this done on BMW's. It will cost me $500 minimum to replace the ignition or steering column based on quotes I got.

This is the original key that I've used since the car was new. This morning I stopped the car, shifted into PARK, and turned the key to shutoff the engine and accessories. The key turned completely as it should, but the steering wheel did not lock and the key will not come out. I messed with it a bit but with no luck. An usher walking by got in and tried it a few times, but no luck. The car will start and run fine, I just can't get the key out of the ignition.
This also means the key fob won't lock the doors, so I have to leave the key in the ignition and the doors are unlocked. GREAT!! I have an appointment with the dealership on Thursday of this week, until then I'm driving my other car and leaving the Sonata in the garage.

I have a 2006 Jeep Liberty Sport. The key is stuck in the ignition. It will still start, but when I go to turn, it's like the key doesn't want to release those last few steps. Which is as safety issue because my car is sitting ready to be stolen. When I called the dealer they wanted to charge me, just to figure out what is going on with it plus labor and parts to fix it.
This is a known issue with the '06 Jeeps and Chrysler is not wanting to do anything about it. At this point, I just need the key out of the ignition. The dealer said they would have to pull the ignition system apart to get the key out which would cause the car not run at all. We tried tapping the key to get it to release and it hasn't done it yet. It did this once before and we where able to jiggle the key and it released but it is not working now.
Again it is a 2006 Jeep Liberty v6 3.7 Liter Engine it is now sitting at about 78000 miles happened the first time at about 50-55000 miles.

I have a 2001 Accent GL DOHC 1.5L (which I believe is the same as your LC model).
One night it started running poorly - missing, bad acceleration - like it was only running on 3 out of 4 cylinders. It was missing whilst idling and would backfire and struggle to accelerate. I took it to a mechanic and they said I needed a new coil pack. So I bought a coil pack from a 2nd hand wreckers that looked pretty good, the car idled better but accelerated worse, like it was only running on 2 cylinders .
So I swapped it back to the old coil pack - and now it wont even start. The engine turns over once then clicks loudly a few times - I think the clicking is from the distributor.

I been having occasional problems starting my 1988 honda accord. It also sometimes dies when im stopped for too long. The problem has gotten worse more recently. The engine will rev and struggle to start. After it dies out i often have to let it sit a while before im able to start it. As i am trying to start it im smelling gasoline.
I thought for sure it was the fuel pump so i had it replaced and is still giving me problems. Today i had to give up and come back to it later. It is fuel injected... What the problem might be?

Brief as possible. Key stuck in ignition. Will come out when battery disconnected. Lift gate stopped working at same time. Believe that car does not sense it is in park. Acts like if the car is in neutral or in gear, in that if you turn the car off in neutral or in gear, the key wont come out of the ignition and the liftgate wont open either. The shifter is not stuck, rear hatch window opens and the car drives normally. Not sure if it is a switch or a sensor.

The security system turn on and off , it's seem like the car doesn't recognize the key, the guy also make a new key and program the car but still the car is not charging, I also order mechanics to see if somethings wrong with the car and he didn't see any problem . I think the car shut down and I need professional guy who know how to program the car...

Drove the car yesterday all was fine. Came home and shut it off. Went to start it about an hour later and the ignition key will not turn. Tried a second key and still no luck. Disconnected the battery and waited for about 10 mins. Reconnected battery still no luck. Wiggled steering wheel and shifter (automatic) still no luck.

Pulled up to customers home and took key out and engine kept running. Disconnected battery, engine and aux turned off. Then Connected battery and power came on as if the key was in. Then put key in and turned with no change in power or engine trying to turn. Disc battery, put key in first then connected battery and truck started. Last stop took key out as well as disc batt and engine stayed on this time. repeated steps above several times to get back. Looking for narrowing the problem,possible ignition key cylinder, actuator or possible bad circuit.

I have a 2008 Accent, automatic, with 167,000 mostly city kilometers on it. 3 times, yesterday and today, when I turned the ignition on it sounded like it was going to start but didn't catch. When I tried again the second time it started. At first, I thought I just didn't turn the key to the right long enough but with it happening 3 times, I am not so sure.
I called my mechanic and he thought it might be the fuel pump. He suggested I turn it to the right then back 2 times, then start it the third time. I have spent a lot on it lately, new tires in April, transmission fluid, also had to replace the tie rod on one front wheel and bearings on the other. If it is the fuel pump, what happens if I don't replace it soon?
