Accent MC (2006-11) :: Shaking And Idling Really Rough
Nov 5, 2014
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.

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.

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/

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 bought my 2012 Accent a few months ago. I have been noticing that when its cold it has a bit of a rough idle. Nothing bad, no reving, but just a general mild shaking. No check engine light either. It happens in park, reverse, neutral, and drive. It stops and runs smooth after a few mins of driving. Since I bought it I have been using Top Tier gas and a bottle of gumout at oil change. Could it be just the way the engine is, since it is a small 4cyl? Like I said its not bad or affecting the way it drives, just seems strange to me.

Our 2006 Forester started shaking very hard while idling or driving. We drove it to the dealer asap, but the violent shaking had stopped. They hooked it up to the diagnostic machine and everything checked out as fine. This problem happens intermittently so the mechanics have not witnessed it. We've even let them keep the car a week and drive it home and back and it never gave them the shaking problem. There is no pattern to when it happens - hot or cold engine, hot or cold outside, just started or been running for awhile, it just doesn't seem to matter. If we give it some gas while at a stop sign it smooths out a bit but it doesn't stop the problem. When driving it still shakes but it's harder to tell how hard. I'm talking about shaking very hard, not just a rough idle.

Having problem with 2016 Accent Sport (or other model) idling rough after smooth driving for about 20 or so minutes? It has started doing this about a month after being purchased. About 700 miles or so on it) When in stick mode it smooths out and purrs like a kitten, but back in automatic mode it idles rough, with Active Eco on and off. I have an appointment to take it in to the dealership 5/7, but I wanted to see what the cause was.

Owning a Hyundai. I have a problem and it seems to be pretty common but haven't gotten anywhere with it yet. Last week my 2004 accent 1.6 manual transmission started running rough. It was idling higher than normal and while driving would not go past a certain rpm (about 2500 if I had to guess,no tach). On the way home from work it was running this way and then started badly misfiring and shut off, when attempted to restart it would not. I pulled the codes with a scanner and got p2400, p0562, and p0121. I charged the battery and replaced the throttle position sensor, still won't start. I can hear the fuel pump kicking on when I turn on the ignition. Also found the ecu 1 fuse blown, replaced it and continued to attempt to start with no luck, fuse was blown again. Like I said I haven't owned the car long and I don't know much about it. I am not sure where to go from here and I don't know how all these symptoms are tied together.

I have a 5speed manual 09 accent I've had it for about six months and lately when I brake around 40 or more mph my car shakes like a champion, on my previous car this was due to old rotors but the car is less that 2 years old I don't think that's the case but idk, my car jus got an alignment last month and I don't hit things so to me it should b fine...

My son phone me from his University saying that whole car was shaking when engaged in R or D. I thought it was a failed GB mounting but turn out to be the RH engine mount. I replaced it but got #3 cylinder misfiring and high idling (1500 rpm) from OBD2 reader.
Fitted new spark plugs and ignition coils swap but still same DTCs. We can hear the misfiring from the exhaust noise. However engine power is normal. But the newly fitted engine mount may not last with the misfiring not resolved. I have cleaned the throttle body too.

My Dad Purchased an 06 Camry, 2AZ-Fe engine w/140,000 miles on it from a family member. He was told that the engine had some issues but wasn't specific about the problem. He recently passed and left the car to me. I used to be a mechanic but i have little knowledge on Toyota. The car cranks/starts easy, but idles very rough. I scanned it and the codes I retrieved were p0300,0301,0302,0304. I haven't done a compression test or a leak down yet, but plan to tomorrow. I also will check resistance on the coils and check the condition of the plugs. I looked through some old posts on here, and seen this engine has head bolt issues. pcv issues. and oil consumption issues. Should i pursue trying to fix this or leave this project alone.

About 2 months ago my 2008 accent 3 dr hatchback started to do what i can only explain as a hiccup while idling and also when first hitting the gas. But I didn't have. Check engine light on. So I changed the air filter and put techron a fuel injector cleaner in it stopped until last night so I am replacing the spark plugs. Is there any thing else i should look in to replacing?

I had a valve job on my 2006 Bmw 750 li, when I picked the car up from the shop the engine was loud ,before the job it was quiet couldn't tell the car was on , it also shakes back and forth while idling at every stop light,and when I take my foot off the gas the engine kind of jerks I have taking it back to the shop several times and they seem to not know what it could be they have recalibrated the valves and it seems to not shake soon after I leave but right when I'm a mile or so away it starts to shake again, what could be causing this? I'm pxxxed I paid them close to 4000 to replace the valves and now the car is running rough.

My 2010 Accent has been stalling intermittently, always when I am idling. I'll be at a stop light, and it will stall, and then it usually starts right up again. It is almost always the same stop light on my way to work, like clockwork, and likewise on my way home from work. Also, sometimes right after this stalling event, the motor will be a little rough on the highway, sputtering like it's not getting gas very well, but then it evens out after a while.
Yesterday for the first time it died and wouldn't start again. I suspected my fuel pump had gone out. I had it towed to a repair shop, but it started just fine for them and they can't re-create the problem. It doesn't give any computer codes at all.

I have a 2010 Accent GS, 5 speed. While sitting at a red light, or even rolling in neutral, the car will just die out. 90% of the time, the car will start right back up, no problem. A few times, though, it would not start right back up.. I put my flashers on, and just keep trying. It eventually starts up again, as people honk and get angry at me, but once a nice guy pulled over and offered to give me a jump and it started right up. I drove right to an autoparts store and had them test my battery, starter and alternator. All came back perfectly fine. There is no check engine light coming on when this happens. There is no code produced. A knowledgeable friend recommended i just change the battery since my car is 6yrs old, 104k miles. He said he had a similar experience and just changing out the battery solved everything. Well, i just did that and it stalled again. That obviously was not the problem.

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.

Whenever I turn on my A/C and the car is in idle, it will turn off. Then I have to put it in park and turn it in again.

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?

My 2007 Hyundai Accent gs shakes really bad while I am accelerating at lower speeds. I thought the front driver's side tire was loose or possibly had an air bubble, but could find no evidence of such. The rim and the tie rod looks fine, but it is shaking bad. It pretty much stops shaking when i reach higher speeds (60+mph), but when I am stopped and need to accelerate or turn it gets frightening.
