Accent MC (2006-11) :: 2007 - Engine Woes / Really Rough And Shaking
May 13, 2013
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.

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.

The check engine light came on after cleaning the engine and the engine runs rough. Where to look. 2007 Hyundai Accord.

Have a 2007 Sonata (2.4 L inline 4) and been plagued with rough/shaking car when initially started and pull to stop, and generally goes away when fully warmed up. Recently had oil change and service area switched me to a lower viscosity oil (5W30 to 5W20) and checked a solenoid and it was fine. Also did a fuel service treatment I suppose in an attempt to flush out stuff........I was a little surprised he didn't pursue talking about tuning up aspects but maybe none of those codes flashed......a repeating code I do have is Code 11.........though I confess when the codes refer to emission stuff I sort of ignore them.......

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?

I have Subaru B9 Tribeca 2006. Week ago started the following problems - after starting up, engine is shaking (rough idle) for a few (20-30) seconds and then it's OK. Then I got Check Engine, Cruise and ABS lights on. Diagnose shows mistake in 1st cylinder. changed spark plug, air filter, checked all connections, cleaned injector and throttle. Lights went out and engine was working as new. but the second day car had rough idle again....

My daughters 07 Accent quit a few days back. She managed to get it home but it was making a noise on the left side of the block before it died again. I started it the next morning and it was rough sounding for a minute or two before it died. There has been a check engine light on for quite some time that I was unaware of. A friend had a brand new fuel pump he sold me (very cheaply) so I installed that yesterday but the starter just cranks with no combustion at all. I will check for spark this AM and if there is none I will likely replace the crank sensor.
I've checked any and all fuses under the hood and all seem fine (although I've never seen the type with the two little "balls" but they seem to by fine also) My question concerns the timing belt. If I have spark and fuel pressure, how do I check for a bad timing belt ? I looked in through the oil cap filler for cam lobes but can't see past what looks like an oil "spout" part at the filler. Also, if the belt is gone would it bend the valves on this motor ? If the belt has stripped teeth and screws the timing I should still get some sort of very rough firing in a cylinder or two, shouldn't I ?

This is my first diesel but my 4th Ford truck. The truck currently has 4000 miles on it. My first incident started at 500 miles when my windshield gasket or lack/loss of silicone on the upper gasket decided to go. This caused a tornado in my cab at 6 am blowing coffee out of my cup and literally atomizing it all over myself pretty much LMFAO. It sounded like a helicopter attack at 40mph when it went. Ended up being towed to the dealer for repair. At around 2k miles the truck started too stink, like exhaust and coolant maybe. I'm thinking it's the DEF or the left overs from a regen cycle (newbie). At 4K miles, it's getting worse. The cab almost feels like deicing in the plane on the runway, nothing but fumes. It literally blows in through my HVAC vents straight into the cab. I'm glad I own the company because I'd be afraid of getting a drug test when I got too work. Instant red eyes. It is not as bad while driving but starts up again at red lights etc. It's a handful of times a week it does this. Things I've checked, water separator, 0 water in diesel. I've tried different gas stations and different DEF brands. Nothing makes it better or worse. I've read that I'm not alone, God speeds too us skunk trucks.

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.

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 started my Accent this a.m. The Check Engine Light is on and it runs really rough. I left it here at my apartment - it's that bad. It's got 27k miles.
The only other thing to note is that it's been very cold (for Northern California anyway) - around 45 degrees F right now.
First-time poster, haven't had any problems with the accent except for a sun visor that was replaced under warranty last week. All scheduled services done at the Hyundai dealer.

I just bought this car from the original owner. She didn't take that great of care of the car. First oil change was done at 8,000 miles for example. Basically if it was broken she would fix it, but didn't do much preventative maintenance.
I just replaced all 4 spark plugs and coils since one was misfiring and didn't want to have to go back in and replace one in another few months. Replaced the AC belt a few days ago since it was cracked and worn. All other belts are fine. I drove the car around for a few hours the next day and it ran great.
Today, the check engine light flashes and then stays on. The car is idling rough at stop lights and acceleration is poor. Previously, the light came on and it was the EVAP system. Not sure which component and I was told it isn't supposed to affect the way the car drives.

Yesterday my car had a rough start (lasted all of 5 seconds) and it threw the check engine light on. Now other symptoms. It was a rough start, almost like a misfire then it idle fined, and drove my 60 mi commute home without issue. I had fine acceleration, gas mileage idle etc.
I got home and turned it off for 10 min and it then started normally and ran fine again. I'm thinking it was just a random miss that threw on the light, but I'll take it to Advance to get the code later today.
I replaced the plugs about a year ago with cheap-o plugs so it may be time for a replacement again. I thought maybe an o2 sensor but there wasn't a drop in mpg, at least anything noticeable.
And its been a few days since I've gotten gas so I'm doubting just a gas cap issue... The CEL did NOT flash, only solid the whole time.

I have been experiencing some issues with my '06 rio5 (same engine as your hyundais). this forum is way more active than the kia forums, so figured id give it a shot here.
I am experiencing a rough idle at start up while the car is low on fuel (<1/4 tank). it idles rough for a few seconds, the check engine light flashes a bit, and then it runs fine.
The car is an '06 rio5 with approx 19k miles on it, five speed manual. Also, sometimes after refueling and it will just shut off while waiting at an intersection. Not sure whether these two issues are related, but thought i would mention it just in case they were.

2007 Accent GLS. I have oil in the intake going towards the engine. I know a bit of a mist is normal but mine drips once I remove the intake. I changed the PCV valve but its still there. Intake filter was also changed and I got an oil change. The car also feels like it staggers once I take my foot off the gas.
Also after driving on the highway for about an hour the car wants to stall if I go above 100km/h but its fine below 100km/h.
I have new spark plugs, got the fuel system cleaned at the Stealer, changed the coils, new air intake filter.

My Accent recently died in traffic. All of the electronic components seem to be working. The engine cranks but does not turn over. I removed the spark plugs and they were soaked in gasoline and the plugs on the 1st and 2nd cylinder had a black residue. I dried them off and tried to start the car again, no luck. The spark plugs were soaked in gas.
Over the summer (5 months ago) 2 ignition coils fouled out and I replaced them along with all of the spark plugs.

I noticed that my car rattles (the engine) when is warm, if the engine is cold by the morning nothing happens, is just after the engine is warm (working condition) some people say gas quality but I use Premium and always the same station, the rattle is after switch gears, just for one or two seconds (sounds like click! click! click!)
Could be that the cylinder head is blown? Oil "Quaker State High Millage" was change 3000 kilometers ago, sparks plugs brand new NGK Iridium IX at the same time...
My car: 07 Accent hatchback 127,000 kilo on it ....

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 mechanic noticed an engine vibration when he was installing my new brake pads and rotors. He noticed the vibration when putting it in reverse. He then checked the engine and mounts. He then asked about the timing belt. I told him the belt was changed at 62,000 miles. The Accent currently has 76,000. He thinks that the belt may have jumped or a counter balancer is not working right. I do not know if the 2007 has a counter balancer. Any diagram of the timing belt, pulleys and counter balance (if it has one). It is a 2007 GLS with auto trans.
