Accent LC (2000-05) :: Jerking /die Speed When Engine Gets Warms Or With AC On
Jul 30, 2013
My hyundai accent 2005, have problem of jerks /die speed after engine get warm, also increase if AC on, when I starts car in morning it works great and no problem but after 3 or 5 km as engine get hotter speed kills,but it happens more or worst in evening at 4 when returning from office and temp is 45+ in riyadh, saudiarabia.
I change air filter, fuel filter, spark plugs, spark cables, also use fuel injector cleaner but still problem remains, I want to tell you its start when I changed engine valve cover gasket due to oil leak, as I changed this problem suddenly appeared, I went to other mechanic but he told me the problem not in valve cover gasket,it is somewhere else he clean my throttle body ,and its works for 2 day only that i felt the problem solved but after two days problem appeared again,there is no engine light power on for any electronic malfunctioning.

Timing belt broke, replaced belt and head camshaft position sensor. After engine is ran awhile 5-10 miles it will not start until it cools down for at least 45 minutes. Even with jumper cables attached.

I have an Hyundai Accent Petrol 1.6L ABS.
While driving the other day suddenly the car started sputtering or jerking while on low rpm and after changing gears
the exhaust is also making sputtering sounds when on idle.
when I press the accelerator the sputters/jerks and then picks up rpm. the performance of the car does not seem to be affected but petrol mileage has fallen.
when I accelerate slowly then the sputtering/jerking is reduced and sometimes not present much. There is also a deep and heavy sound of the engine running heard inside the car (which has been present before the timing belt change)
I took the car to the workshop and attached the OBD.
the codes P0340 P0112 were present. we now erased the codes and the mechanic checked the sensor wire plugs for the cam sensor and air sensor saying it looks fine. on attaching the OBD again the codes were not present. However the sputtering/jerking continues. (the fuel pump and filter were also checked to be ok)
My Timing belt has been changed approximately a month back. My car does not run much (Approx 40kms a day)
My questions are
1. can a bad timing of the timing belt have anything to do with this and thus giving these codes?
2. Can there be something wrong with the exhaust due to which this problem is taking place?
3. what could be possibly wrong with the car?
4. Can this result in any damage to the engine?

Sometimes I loose the idle speed and the engine stops when I stop the car but it could be started again with full throttle it doesn't happen always it happens from time to time > I changed the MAP, IS actuator and TPS .The fuel pump and filter is new .In rare cases engine stops during driving. How about flash programming the ECU

My standard 2002 accent is undriveable and at the mechanic right now (100,000km). For the past few weeks the car has driven very jerky. While in first and second gears if i accelerate too quickly it just jerks/slips and has very little power.
Yesterday the check engine light came on and i got codes P0300, P0302, P0303...misfire in cylinders 2 and 3. Checked this forum and decided to buy new spark plugs (last replaced plugs and wires 1.5 years ago). Got into the car and could go more than a block because it was jerking and then kept stalling. Replaced the sparkplugs and nothing changed. Had it towed to the mechanic...after a few hours he said he had cleaned the exhaust manifold and it was driving fine. I picked it up and a block away it stalled again.
The mechanic now says 3 of my fuel injectors need to be replaced and the fourth will probably go soon and it will be about $700 to fix. Does this sound right for these codes?
I called hyundai parts and they told me each injector is $236...he also told me he doubted they had to be replaced cause he has never seen an accent have fuel injectors replaced and also they rarely sell these injectors, he said it was probably something electrical.
I have found 4 injectors on ebay for $200 but is this really the problem? The mechanic says it is 100% the problem. But from reading the forum I dont think so.
Also wanted to add that i often noticed the smell of burning plastic. Smoke seems to be coming from spark plug area when i notice the smell but nothing looks burnt/melted.

This is in regards to my daughters 2009 I4 Sonata. In cold weather, like we are having now in Chicago. After the car is sitting all day or overnight, it will jerk (nice technical term) when accelerating until the car warms up. What is the problem is and how to resolve it?

I drive a 2000 Ex V10. My truck has been having an issue at idle after it warms up, almost every time after it sits and cools down.
My problem is that once the truck warms up, it will drop down to 500 rpm's and will have a hesitation/miss/lope for about 20 seconds. When it does this I can hear the exhaust making a sputtering sound. On two occasions during windy rain it would hesitate while driving but then straighten up within a half mile or so and be fine. I have changed all the boots, cop's and plugs and don't think that is where my problem is.
What I can't figure is why it seems to hesitate/lope once it warms up! This problem not related to a failing boot, plug or cop?

When I'm on highway (between 90 and 120 KM/H) I heard a whistle when speed is stable. it happen frequently in the last week. I notice it happen approximately at 95 and 110 KM/H. When I remove my feet from accelerator, I don't hear the noise anymore.

A few months ago my automatic 2000 hyundai accent GL was having problems reversing. Some times it would, sometimes it would move a few feet then fall out of gear and stop, sometimes it would not move at all.
The reversing problem fixed itself about a month ago.
Recently i started having problems accelerating, it was noticeably slower to get to speed and had problems upshifting.
Today, it started to make a buzzing when in Drive, while decelerating after getting to speed. This buzz is nonexistent in neutral, 2nd, or low gear.
Here is a video of the sound it is making, with captions to explain what i am doing... 2000 accent transmission problem - YouTube

I have a '05 Accent GLS Hatchback. 5-speed, manual transmission with about 82 thousand miles on it. I bought the vehicle used about 2 years ago. Ever since I've had it, its been a little jumpy in first gear when going at very low speed. Especially during traffic jams, barely pressing on the gas will cause it to jump a little bit until you put the pedal down further. Lately its starting to do something similar when it 4th gear. When you push your foot on the pedal it jumps a little and does the same thing when you take the foot off the pedal. What may be the cause? O2 or TPS sensor maybe? It did give me a flashing check engine light for about 10 seconds this morning but it hasn't done that since.

3 times now in the last week, my 2000 accent has stalled. each time it was at a low idle, slow moving speed. I was rolling up to a red light twice, and gliding into a parking spot the other. There was no coughing or sputtering. It just stopped. Each time, after about 20minutes or so, the car fires right up. it happened twice today after about 4 miles of driving. If the car sits for a day without running (on an off day from work) its a bit hard to start sometimes, but not consistently. Does this sound like a Crankshaft position sensor? or possible a fuel filter?

I have a 2001 accent 1.6 5 speed manual. When I put it into reverse it dont fully engage until I give it some gas and then it slams into reverse with a bang. I am not really sure but I think it only does this with the car is cold I may be wrong though it started this a few weeks ago.

Have replaced BOTH half axles. Clicking sound present when driving - does NOT change when turning right or left. Seems slightly affected by acceleration/deceleration - makes clicking slightly louder/quieter. Clicking is DIRECTLY proportional to speed - slows down until car stops. Transmission works fine, fluid level is correct. New trans fluid and filter. What the heck could this be? Wheel bearings seem solid - jack up car and try to wiggle wheel - solid as a rock both right and left sides. WHAT ELSE COULD THIS BE???

I'm having an issue with my transmission. When driving it shifts just fine, but I have to let it accelerate slowly. If I press to hard on the accelerator pedal the engine ron races. So I ease up and it catches and slowly accelerates. For example going up hill, I press the accelerator and the car doesn't speed up, the engine races, so I have to just let the car slowly increase in speed by lightly pressing the gas pedal, no get up and go! Only occurs in 4th and 5th gears. What could be causing this. I have already flushed the gear oil as I had to replace the output shaft seal as it was leaking.

I have a 2005 accent gls. I use the car for deliveries so a lot of stopping/starting. when the car is hot, the AC compressor will shut off after 5 seconds, and not re-engage until about 20 seconds, then only on for 5, so not keeping cool air. I noticed when I turn the AC on, the condenser fan (i think) kicks into high speed so I assume that's what it should do, but when the issue is happening, it does not go into high speed. the shop I went to wasn't able to determine the problem. they checked pressure and evacuated the system. when it works, it blows cold as it should.

2005 hyundai accent, I've noticed something unusual with my trans, whenever I start driving at lower speeds ( which I do all the time to save gas) the transmission shifts into 2nd and 3rd just fine, but in 3rd gear ( at around 2.5 rpm ) the RPM gage goes down a little bit ( about 2.1 rmp), it almost feels like it went into 4th gear and it happens really smooth, it almost feels like its supposed to do that, the car later shifts into 4rd at around 3 rpm, there's no jerking, stalling or sounds at all, this does NOT happen when I take off at a higher speed and acceleration. This transmission has 55.000 miles on it and besides this it works perfectly fine.

I have a 2004 Accent with 150,000km on it. I've done a number of jobs on it, and I find it to be a relatively DIY-friendly vehicle. A little while ago I had an issue where it would die after warming up, sometimes at a stoplight. Otherwise, it would intermittently fail to start after it had been parked for a very short time. This was fairly obviously the crank position sensor, which I replaced. At this time, I haven't had the same issue again.
Since that small repair, however, I have been noticing other issues. From inside the cabin I can hear a distinct whine that climbs 1:1 with the engine RPM, whether or not the clutch is engaged. Once the RPMs hit the power-band(ha-ha), the whine is joined by a metallic jingle. From outside the car, both whine and jingle are audible through the entire RPM range. It sounds to me like a clear case of bearing noise coming from the belt and pulley system.
Since this whine started, the car has been giving lazier starts, requiring slightly longer to fire up. The noise changes significantly when the AC/defrost system are engaged, although I'm not sure if this is because the faulty part is connected to that system, or because the RPMs drop once it's engaged, both, or neither.
I will be doing a timing belt and water pump change before the snow flies, and I would love to find the parts that I need to treat the jingle at the same time as the rest of the belt system replacements.

My old car has this problem when it's on highway the steering wheel shakes quite a bit. Is it a wheel alignment problem or wheel balancing problem? Since I've just fixed the transmission I am driving this car more often(to save gas) and this problem is really annoying.

My i40 (18 months old and already on it's 5th problem) has just developed an enormous noise (thud thud thud) when going over 15mph and gets faster with speed. If I go into neutral and turn the engine off at speed it is still there. The crazy thing is as soon as I veer or turn right it stops but when I turn left it does not stop. It's really lot and I can feel it through my feet and on the steering wheel. I am taking it into Hyundai (again) but I'd like to understand possible issues before I go in.
