Accent MC (2006-11) :: 2007 - Engine Runs But Won't Idle Without Foot On Gas Pedal
Mar 29, 2012
Changed timing belt after several teeth being stripped. Engine runs but won't idle without foot on gas pedal. Drives smooth as long above 2000 rpm. Thinking there is one or more slightly bent valves. Quadruple checked timing marks. Coils are good. Fuel injectors are good. Spark plugs are new NGK's. DTC's are 0300, 0301, 0302, 0303, 0304 - misfiring.
Have a line on a low mileage head with warranty. 2007 Accent 1.6L?

Have a 06 Grand Caravan 3.8L that suddenly quit and would start back up easily enough, but one had to keep foot on the gas to keep it going.
I pulled two codes:
P0123-throttle postion sensor 1 high
P0508-IAC valve sensor circuit low/undercurrent
So far I have removed the IAC and cleaned it with throttle body cleaner, cleaned throttle body out as well with the spray, installed new EGR since it got mangled trying to remove it for cleaning. Removed the TPS connector and with key on, took measurements and I am getting a reference voltage proper ( almost 5 volts). I then back probed the connector once it was plugged back in and again things checked out, the reference lead was varying between .7 and 4.7 volts as I manually moved the throttle plate.
I had switched out the IAC with a used one, from an engine that had been running before being parked, but it made no change.
Note: I have a new TPS but am holding off on changing it until I investigate whether or not it may have a clogged fuel filter causing it to stall at idle speed. Now if can just locate where it is..the sketchy diagrams in my Alldata program are useful.

I have a chirping/ squeaking sound in the engine extremely noticeable on idle. It's not the actual belt because it continues the noise much after the car is heated up. Have no clue what it is, I have 145000 miles. Also when running the engine hard notice a hissing sound sort of like turbo at high rpms especially with ac on high.

I would like to know if for the Accent 2003 there is a component that commonly fails and causes a P0108.
Vacuum seems to be ok. At least I can't find any leaks. Pressure at idle is normally at about 30kPa (4.3PSI). It ranges normally between 30 and 50kPa (7.2PSI). When the fault was set it indicated 125kPa (18PSI).
Sometimes the engine runs unstable at idle.
It seems to be an intermittent fault. If I clear the fault it can take about 2 days to reappear.
Otherwise I will have to go through checking the MAP sensor itself, wire harness, idle motor, is that about right?

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.

If I dont constantly keep my foot on the gas pedal then my car will die.

There is a low buzz sound when I have my foot on the gas pedal. It doesn't seem to effect acceleration or anything. At first I thought it was a wheel bearing but the noise disappears when I remove my foot from the pedal. The Sebring has 65K miles on it.

Ok so I have I 2007 hyundai accent with a weird problem. When the car is in normal operating temperature (180-210) and stopped at a stoplight or stop sign the car will have a fluctuating idle. This problem only happens when the car is at idle and with the heat or air conditioning on. With the heat and the air condition off the car will do it once in a great while. Things I have done so far. Replace the pcv valve clean the egr. To me it sounds like a voltage problem like the car is having too much load at idle. But I am unsure. Took it to a mechanic the other day and he couldn't replicate the problem.

Have a 1977 ford f150 with 351m with a motorcraft 2150. Had ( who I believe was a reliable source ) rebuild carburetor for me and after putting back on I can only keep engine running with foot on pedal. I turn idle mixture screws all way in and then proceeded to back out equally. This does not appear to be doing anything. I did turn the choke 2 notches to lean and was able to get it to idle but it wasloping so bad i shut it down and put the choke back to the middle setting.

I drive a '99 Chevy Tracker with the 2Liter engine, a 5 speed manual transmission and 110K mi. on it. When I lift my foot from the throttle pedal in preparing to shift gears the engine takes a very long time to reduce it's RPM. This is a problem, when up shifting, as the transmission is spinning too fast for smooth gear engagement.
The engine idles normally under all other circumstances. It is only slow to decelerate whenever I lift my foot from the throttle pedal. This makes up shifting very slow and/or causes the gears to sometimes grind slightly.

As the title says, I have an 02 Supercrew with the 5.4. The engine starts when cold and runs fine but sometimes when I start it hot after running for a bit, it will stall out unless I keep my foot on the gas pedal. This seems to only happen on hot days. It was about 90 F here yesterday and I drove it to a shopping mall after supper - maybe 5 miles. It sat for maybe 20 minutes and when I re-started it, it stalled out.
The tach needle just drops slowly to zero and the engine stops. It will re-start without any problem but will only keep running if I keep my foot on the gas and keep the revs up a bit. It has done this a few times in the past few years and only on hot days after it has been running and then sat for a few minutes.
What I should look at? It does not throw any codes and generally runs ok after a few minutes. For example, last night I managed to keep it going by shifting into neutral when required until I got back on the road. I drove 2 or 3 miles and at the next light, it acted like nothing happened.

My 2007 Ford Focus runs in high rpm. When I put the car in park it sounds like someone is slightly holding gas pedal down. I have to use brake when on road more frequently. Vehicle will run over 25 miles per hour without touching gas pedal.

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.

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.

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 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.

My 2007 Hyundai Sonata has a knocking sound when I put my foot on the brakes. It has 82,000 miles. It still has the 100,000 mile warranty. The brake shoes was replaced last year. Does it need new shocks?

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.

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.
