Accent LC (2000-05) :: 2000 - Misfiring Upon Acceleration And Engine Revving
Jul 24, 2011
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.

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?

I got a 2002 accent 1.3 si, engine warning light comes on but doesn't seem to affect cars running, no misfires, no stalling, still good acceleration and mpg, occasional engine revving on its own, changed tps sensor and engine revving on its own was worse. Was told by hyundai mechanic to disconnect battery for 30 seconds and if light went out it was either faulty tps sensor or an intermittent non constant fault reading, light did go out for some time but is now back on.

I have a 2000 model accent manual trans its just recently clocked 200 000 km I know the car has had problems but they are getting worse. Occasionally I have Problems starting the car in the past but it usually takes no more than 5 turns to get started but this is getting worse the other day it took about 5 min maybe more to get the car started I am guessing my starter motor probably Needs to be changed.
Next problem yesterday after I put a full tank of Premium 98 in the car its starts to rev itself changing the sound and note of the motor running constantly it has done this in the past but not so severely and It only seem to do so after putting petrol Especially when I put fuel From a servo I don't usually go to the car would have stalled more than once but didn't only because I tried to keep the revs up when it sounded like it was gunna die also I am pretty sure my fan was making some weird noises but the car has had no engine Light show and no Overheating.

I have hyundai accent 2005 1341cc 86hp, with BRC LPG kit. When i start the car at the morning, the engine misfiring around 500rpm for a few second (5sec-10sec)...
Sometimes the engine start ok in the 1100rpm - 1200rpm and when I touch the accelerator then misfiring again!
The car have 133.000km (11.000km with LPG).
I have replace the petrol filter 2 days ago and the all electric system without multiplier. I have clean throttle valve and the injectors with stp cleaner.

I recently changed my Hyundai Accent 2004 rings and top cylinder. a day after I left the mechanic garage, the car started bringing out white smokes particularly when I rev.

I have replaced the MAF sensor, TPS sensor, and fuel filter. Like the title says...if I rev the engine ...as soon as I let off the accelerator the engine stumbles and almost dies...then settles back down. I initially pulled codes PO121 so I replaced the TPS. PO103 so I replaced the MAF sensor. PO112..did not address directly as I assumed the MAF was causing. PO1123...again I hoped the parts I replaced would solve the problem. Initially the engine would just drop out while driving just for an instant and then be fine...also I had the 4 codes mentioned above. The only code that has returned is the PO121. I just got done replacing the fuel filter and things seem to be worse.

Just the other day I was driving my car till I've noticed the gears started slipping. At first it was having some issues shifting through the gears (automatic transmission btw). As soon as I got off the highway, I parked in a parking lot just to check underneath the hood. Everything looked fine, went to pull out of the parking lot, no reverse. The gears started to slip up really bad. I noticed that the RPM's kept on reving up and wouldn't go any faster than 20mph. I went to an advance auto parts to get automatic transmission fluid. Still having the same issue and no reverse either. I had to park the car at a location to get it towed back to my house. Some people are saying my transmission is bad, some say it could be a real simple fix. Where to start diagnosing this issue. The car was driving normally until last Monday. My question is where should I start to check and what can I do to see if the transmission is completely shot??

I have a 2002 Hyundai accent 1.6L w/ 190,000 miles. Around Christmas one cold morning right after getting gas at a grimey service station my car started running like crap misfiring badly. Kicking and bucking it barely got me to work (6 miles). I took the car to an Advanced auto and had them plug it in to check the engine light. It was throwing multiple codes P0300 (Multiple Misfire Detected), P0301 (Cylinder 1 Misfire Detected), P0303 (Cylinder 3 Misfire Detected). I told the guy at advanced that I thought it was bad gas and he agreed, so I put some dry gas and Lucas oil gas treatment in it. The problem seemed to get better within 50 miles, only misfiring when I drove it hard.
The problem has come back and this time the gas treatments are not working. I am getting the same two codes along with a new code P0133, (HO2S-11 (Bank 1 Sensor 1) Slow Response) and the same symptoms, and to top it off my flex pipe has rusted out (for the second time).
So now I don't think the initial problem was water in the gas, and I am not sure what to make of it. The problem seems to happen more noticeably when I push the engine (first gear, and when accelerating) but then seems to get better when maintaining a constant speed. Also, the misfiring happens all the time but more noticeably when the engine gets to running temperature. First gear is by far the worst when the engine is warm.
- The car got a tune (filter(s), plugs wires) up about 6mo ago
- The timing belt is old about 90k on it
- A new crank shaft position sensor a year ago
- New O2 sensor (the 2nd one past flex pipe) 6mo ago
- Burning about 1qt of oil (synthetic) every 3k miles but no smoke
- The car has the original clutch w/ 191k on it!
This is where I stand. I don't care about the flex pipe or the timing belt. Unless I can defiantly pinpoint the problem to one of those two, the car has so many miles on it, to start dumping that kind of money into it doesn't make sense. I have put a spark test light on each of the plugs BUT the problem does not happen when the car is idle so it showed me nothing but properly functioning plugs. I was thinking the ignition coil (its original) but I think that would throw a code.

I have a 2002 Hyundai Accent 1.6L automatic. I just bought it today. It has 171,000 miles. The car is misfiring. It does it when I give it gas. It won't misfire if I only give a little gas but if I was to drive it then it spits and sputters. I put new wires on. what are some common things on these cars. I am new to a Hyundai.

I have an 02 Accent 1.6L that has about 190,000km on it. It is now misfiring under low rpm's (anything under 2000) and the engine light will flash and then go off after about 5 seconds. Once the engine light went on and stayed on but I got the code read and reset it. The code was P 0303 Cylinder 3 misfire. I replaced the coil pack since that is apparently the common cause of this issue.
No luck with the new coil pack still have the same problem. I started smelling gas about 1000km ago so I assume that it is burning rich and putting raw fuel into the engine. My spark plugs are under 10,000km new and the wires show no signs of any problems. My next thought was to buy a new MAF sensor and hope that is the issue.
What this could be? FWIW the engine seems to run a little better for about 5km after using a throttle body clean on the TB. It also runs minimally better when I use a Lucas fuel additive.

My friend has 2000 12v vr6 auto and recently he experienced his car bogging under acceleration. He had the plugs and wires recently done to solve the problem and the problem went away for a day and has since returned. I scanned it and here are the codes that its threw. After doing some research i'm thinking its the coil pack, since it was pretty foggy/damp today (when the problem started again).
17626.p1218 - fuel injector for cylinder 6 (N84): short to b+
16690.p0306 - Cylinder 6 Misfire Detected
16684.p0300 - Random/Multiple Cylinder Misfire Detected

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 own a 2000 accent. Broke down, called racq, they said it was electrical problem with fuel pump and my car would kick over after someone cranks it and another person bangs the underside of the fuel tank a few times(exterior). then broke down again and car wouldn't start at all, had no spark would only crank not kick over, I took it to a mechanic and he found out it was the fuel relay switch so he replaced that and the car was running again, however it was only running on 3 cylinders and the fuel light would flash/turn on for seconds/ flick on and off even with a full tank.
Took it back to the mechanic and he said the fuel lines were blocked and needed new fuel filter so after he fitted all that was still running terrible, would misfire, fuel light still flashed and driving it around drank the fuel. Found out that it was the first cylinder that was the problem. I changed the sparkplugs and no difference
So I went to a car wreckers and replaced the 1st fuel injector (got it for 5 dollars off an accent that was wrote off from the back end) once i fitted the injector it started to run better. It is now running at about 75%. doesnt go as hard as it use to, still misfires, still drinking the fuel and the fuel light is always off and on when I am driving. It has low revs in idle mode so it rattles/shakes heavily as well and smell of fuel in the back seats every now and then.
oh and a side note - drove it a few nights ago and the clutch pedal is 'loose'... as in the grab is near enough clutch in 7/8ths of the way(near the floor) and when the clutch is fully out there is alot of 'play' which is when you press the clutch in a quarter of the way its nothing, no tension or anything just floppy, but im not 100% sure if the clutch cable needs tightening or something worse( i only replaced clutch about 2 months ago so it couldn't be burnt out?)

I have a 2001 Accent GL 1.6L Automatic.
Yesterday it started acting up on the freeway. I was driving about 50 during traffic hour when it started revving. I got off the freeway and moved to 35mph on surface streets, the revving continued at lower speeds but much worse (4-5k rpms going 10-15mpg). Doesn't seem to do it in idle or park. If i shut the car off it'll drive fine for a while then start acting up but when I was driving, after awhile, it did return to normal.
What could cause the problem? TPS? Transmission? Sensor of some sort?

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.

I have a 2000 Accord with a 2.3L 4 cylinder and manual transmission. I just changed the timing belt, balancer belt, water pump, tensioner wheels and other external belts. I now get a bad engine vibration at idle and when backing up and pulling forward. The vibration is quite noticeable in the steering wheel. Revving the engine smooths it out at certain RPM's. I know this isn't right and its got to be limited to something I just did. I followed the instructions in the Honda service manual and thought that everything went back to gather correctly. I double checked the timing and balancer alignments. The motor mount on the drivers side is simple and all went back together correctly. Is there a way to verify correct timing belt and balancer belt alignments without tearing it all down again?

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.

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 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.
