Accent LC (2000-05) :: Loud On Start, Idle And Acceleration
Dec 12, 2013
I have a 2005 Accent with just over 35,000 miles on. Last night (in extreme cold here in Chicago), the car started running loud. Loud on start, idle, and acceleration - normal when maintaining speed, even at highway speed.
Since the loud sound first started, I have driven about 100 miles (had to for work, no choice). The sound is pretty much the same - definitely in the front end, and the best way I can describe it is a much louder version of the normal sounds you would hear - idle sound but louder, acceleration sound but louder, etc.
No warning lights have come on, car hasn't shown any signs of overheating on the gauges, etc. I had a somewhat similar issue with an old '99 Saturn SL2 w/ 115,000 miles - but in that instance the flex pipe had corroded and completely separated from the rest of the exhaust system.

I have a 2005 Hyundai Accent with the 1.6L in-line 4 cylinder engine w/ 160K miles. Over the last few months, I have noticed that when I run the A/C, the car has been at idle for a while, like at a stop light or in park at idle, and I have been driving the car for awhile in the afternoon (summer here), the engine sputters and hesitates on acceleration. The engine makes a pinging, sounds as if it's misfiring and then bolts like lightening, especially when I turn the A/C off. The mpg has declined. I barely get 21 mpg. The car does not have an inline fuel filter, only the "sock" in the tank. I have changed the spark plugs, plugs wires and have run two cans of Sea Foam FI cleaner through the fuel system and the problem still persists.
I am clueless to what could be causing this other than my injectors are still dirty and need a heavy duty cleaning. Could it be an alternator problem because I have noticed the dash lights and headlights get brighter. Could the ignition coil be going out. The car idles fine and the problem disappears when I shut the A/C off and only seems to do this when the weather is hot!

I'm an Accent 2000 gs owner and since a few days i had this problem. It has a bad idle and looks like it will stall... need to give some gas to stay alive.
Bad acceleration too, it misses some gas. (puffing, rumbling, shaking a bit). After accel, it's ok until the next red light.
Now I can't even drive cause it's worse. (too difficult to accelerate). Is it a sensor?

Symptoms:
- Check engine light: misfire on all cylinders, and "lean fuel trim at part throttle".
Started with changing leads and plugs without improvement. Then I found the tank ventilation seemed to be clogged, as there was a massive vacuum when opening the filler cap. Checked the canister and replaced a couple of corroded lines. Also used compressed air to blow through the canister and lines up to the Evap-purge valve. Seemed to be OK afterwards (no vacuum), but still misfires.
Changed the Mass Air flow sensor, and it seems the misfires got better, but instead I have some other issues:
- Hard to start when cold. Starts up fine for a second then sounds like it's getting to much fuel and dies. Possible to keep it running if pumping the pedal or holding it at higher revs.
- Rough idle when warm. (Same as before I changed the MAF and plugs/ leads.)
- Drives and runs ok when out on the road.
- Pulled the cable to the Idle Control Valve without any change in idle...?
- Got flashing engine light and "misfire cylinder 4" when giving full throttle on low revs and seond gear up a steep climb.
What could cause this?
- Temperature sensor?
- O2-sensor?
- Idle control valve?
- Coilpack?

Car died at idle on park. Tried to start it back up and was only getting crank. I took it to a local mech and he said my timing belt failed. I paid for the repair and the car still wouldn't start. The shop said the ecu went out. I replaced the cam position sensor and main relay under the dash. Still not getting it to start. I also have a ecu from an 05 accent, would this be plug and play? What else can I do?

I have a 2000 accent. Automatic tranny with 167000 miles. My current problem is the car is misfiring upon acceleration and engine revving. I have to accelerate very slowly to minimize this but i once the engine revs up enough I can give it more gas and it will rev normally with plenty of power. I have had to unplug the maf to keep it driveable. Ive never had a car stay running after disconnecting the maf so this is strange to me. My accent barely stays running with the maf connected. I just got the car from my dad and he had it fixed and it ran good for awhile with the maf connected so I don't think it is the maf. But the same problem came about and we had to disconnect the maf again. And he cant remember or is not sure what was exactly fixed on the car. I've read up about the purge control valve and havent had a chance to check it out but some of the symptoms fit.

2002 accent 1.6 motor and 5 speed,when I take off the motor sputters for a moment then is fine and if I let it slow down in any gear and step down on it it will sputter again then is fine, so far I have changed the plugs and air filter cleaned the throttle body and MAP, the wires and timing belt were changed out not long ago, took it in and hooked the machine to it and it said misfire bank 1 oxygen sensor upstream so replaced it and still have the problem, the body has 200,000 on it and the motor 100,000.

While driving on the freeway my car started to surge as if it was starving in fuel. I had to press more gas to go the same speed. My gas tank was at a 1/4 full so I pulled into the gas station to fill in gas. As I was leaving my car could not accelerate while pressing the gas pedal. I could floor the gas and it would go only five miles an hour! The engine temp was okay, no engine lights, and no weird smells. I was fortunate to be close to home and slowly made it letting cars pass me on the side. I called the road side service who towed my car to my dealer. They checked for codes, ran fuel injector cleaner twice through the system, checked the fuel pump, and the pressure on the fuel system, no problems. The third day they gave me a Sonata for a loaner and I allowed the service manager to drive my car to see if the problem reappeared. No problems found and I picked up my car today. The problem hasn't reappeared yet but I am keeping track of any rough acceleration or idle.

I have a 2008 Accent SE and I'm having some issues... The car was driving fine the other day all the sudden check engine light came on started flashing then and just stayed on. This happen before and the car was under warranty so the dealership fixed it but now it ran out and it's happening again. Anyway the car is running very rough at idle like the car shakes and acts like it doesn't want to run. Also when driving it honestly feels like the car has no power or acceleration what so ever. I replaced the air filter with a brand new K&N filter, I also changed the spark plugs today. I put NGK's in and the problem is still the same. I had it hooked to a code reader and it said I had a misfire in cylinder 2. I thought the plugs would have fixed it but I guess not.

I drive a 2001 Hyundai Accent. About a month a go the CE light came on. at first, the car was driving fine so I thought nothing of it. Then I started noticing that the acceleration was sluggish and when it finally accelerated, it basically slingshot forward. What could be wrong. There's no smell, rattling or anything else. The only thing I noticed was the engine was a bit louder.

My problem is this: when I am driving and press the throttle hard from low rpm (anything under 2000-2500), the car will struggle to pick up rpm, and be incredibly sluggish to accelerate, until it reaches around 3500 rpm, at which points it returns to normal. Whilst it is struggling to accelerate, the exhaust sound is almost like a subaru, in that there is a series of small burp noises which stop once it returns to normal acceleration. It only whilst attempting to accelerate from low rpm that I have this problem, i.e. idle plus mod-high rpm is fine.

My mom has a 2011 GL Hatchback about 20k km's... She decided to take my car this Saturday without telling me and I was stuck with hers.... All of a sudden the check engine comes on and at idle there is like a bogging going own. (Shaky putt-putt-putt-putt) early acceleration is lacking power and it smooths out at higher rpm's.
I can do minor things on my own like plugs and brakes, I would love to be able to get it running smooth again.

I have just changed my clutch and machined my flywheel on my 1.5ltr 16v dohc 2000 lc accent. I used all the correct trans fluid and refilled and bled the clutch fluid. It takes of from lights like a new car but if you put your foot down around 40kph it revs out a bit and does so through all gears untill you reach a bit of speed. What is going on?

My 2000 accent (manual) suddenly started making a LOT of road noise - like I'm driving on off-road tires. It's speed-sensitive. At 20MPH, it sounds like a trilled R, spanish style - like in "perro." Above 30, it's just a roar.
It's there even with the car in neutral and engine off. It goes away completely when turning right, such as on a freeway exit ramp. It does not go away when turning left.
CV boots are intact, no grease to be seen. It started with a set of tires that were due for replacement, so I replaced 'em and the noise hasn't changed. I've jacked it up and don't notice anything unusual when spinning the tires by hand. I even had wifey spin them while I was under the car feeling around the shafts - nothing interesting.
Also, occasionally, I hear a single "doing" sound (like metal rod striking something), from what sounds like front center of the car. Might be unrelated, but I never noticed it until the road noise started up.

After scouring through hundreds of threads on this forum (which is Awesome, BTW), it seems as if this misfire / rough idle thing is fairly common (which is scary!!). CEL is on steady. Had the codes pulled; P0301, P0302, P0303. At the recommendation of the mechanic, I had the plugs replaced...no improvement. He then replaced the ignition coils...no improvement. Just finished replacing the MAP sensor. This actually had a VERY temporary positive effect. However, after about 5 miles of driving, the misfiring returned. Took the car to the Hyundai dealership, and they acted as if they didn't want to fool with it. They referred me to a couple of local repair shops...????

I have a 2002 accent 1.6.(272,000 miles) It has been having this issue for awhile now. It is very slow to accelerate, seems like it is losing power. Also if I press the gas pedal hard it does not want to shift correctly unless i back off the gas pedal some and then it will shift fine. I have had the transmission checked and it has no issues (transmission has be replaced with only about 80,000 miles on it). Also if i try to run the AC it really looses power. It currently does not have any diag codes when I have it scanned. So far I have replaced spark plugs, ignition coil, fuel filter, and a diode that I was getting a code for. I am just curious if there is something that could be causing the issue that will not report a code.

I have a 2002 Hyundai Accent with a 1.5L SOHC and manual transmission, with 207,000 trouble-free miles on it.
I have recently noticed a hesitation under acceleration. It happens most frequently under hard acceleration under lower RPM, if I'm close to lugging the engine. The engine "hiccups," almost like it is missing a cylinder. It will hiccup 2-3 times until engine RPM's increase, then smooths out.
What the cause may be? Last changes: Plugs at 175K; Plug wires @ 160K, Fuel filter @ 100K, Timing belts at 60K, 120K, 182k. K&N air filter cleaned at 50K intervals, last time @ 200K.

My '03 gives a rattle sound under load/acceleration conditions. This does not happen during the warm up period, so it appears that the engine runs lean under acceleration. There is no check engine light on for this. Approx 172k KM, (100k miles). The noise appears worse when it is hot/humid outside. I have run a can of Seafoam through it (half in the crankcase, half in the fuel line), and that doesn't seem to have worked. Therefore, I don't think that it is the injectors. Possibly fuel filter (still original)? Any easy way to test?

I have a 2004 Hyundai Accent 1.6 DOHC 5-speed Manual Transmission ... so here is my problem;
Regardless of whether I am going from a complete stop or if I am simply changing gears the acceleration is practically non-existent, sometimes taking up to 3 minutes to accelerate just 5 mph. While I am driving at a consistent speed of 65 mph, the RPMs will randomly jump from 3000 to 4000 or 5000 with no apparent cause.
I have been told everything from putting air in the tires to replacing the clutch. I do not have the time nor the money to try every option of fixing this issue. I need to attempt to narrow this down to as few probable causes as possible.

I've suddenly developed a loud buzzing noise from my air-con system. I checked the hmaservice website, but the images don't look anything like what I have behind my glove box. I have a right-hand drive vehicle.
hmaservice says to remove the outside-air/recirc cable, and the picture shows this coming in from the left, where the center console would be on a LHD car. Mine comes in from the right of course. That is where the mirror imaging ends!
The service pages say that the filter sits behind this cable, and there's some sort of "hook" to remove to open a flap for the filter. There's no hook or anything like the images on my car.
