Accent LC (2000-05) :: Stumbling On Acceleration
Apr 12, 2014
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 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 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 2002 7.3 Excursion with DP Tuner. Truck has 167K on it. My check engine light came on when I was driving to work this morning. Stayed on for the ride home. Appeared to drive ok - a little rough - but it has been that way for a while. When I got home I plugged in the AutoEnginuity and this is what came up:
So it appears I have a glow plug issue. That does not surprise me as I have had some rough starts this past winter. On a whim I ran the Cylinder Contribution Test and it completed successfully. Yet when I started the truck again it completely falls on it's face when accelerating. Here is a link to a video: [URL] .....
It did this once about a month ago. I was driving to work and stopped at a light and when I tried to accelerate, it did this. I limped to a gas station a 100 yards away. I let it sit and started it up, drove home. Went in the house and did some googling and of course after I came back out, it worked fine. Has not done it since.

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 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 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 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'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?

My 2011 stick shift no air Accent has a hesitation or stumble on light acceleration that comes and goes. It may not occur for weeks then re-occurs. It is hard to reproduce intentionally. It never occurs in cruise. The CEL is not on. Most often occurs at 1400 to 1500 rpm with slight acceleration or a slight increase in load as coming to a slight hill. I tried injector cleaner a few times and changed air filter. It seemed more reloaded to induction airflow so I changed the MAP sensor. I understand the 2011 Accent does not have a MAF sensor. It is still occurring. It is fine in steady cruise as well as in hard acceleration. I am wondering if it is a TPS sensor problem. It has 60,000 miles and otherwise runs fine.

I have been experiencing pinging and crackling noises on acceleration from my vehicle it was purchased from the dealers May 2012. The problems started in October and I have been back and forth with the dealers for the same problems over and over and getting additional problems. Not to mention they keep saying that the problem is fixed and as I leave the compound I hear the noises.
I took it to have an independent scan from the dealer as it is now 5 months of run around with the issue not being resolved and I found out I have a bad ac compressor, steering rack and shock mount.

My gfs car (2012 accent) makes a rattle but more specifically it makes this rattle in about 3 gear under acceleration but not heavy acceleration (slow accelerate in a higher gear) at about 1500-2k rpm it makes a rattle and if i really get on it in the gear it keeps going, the second i let off then get back on (lightly) no noise but when you depress the pedal a little hard it does it again (auto trans by the way) I've heard of this before only issue is I don't remember where or who (useless, and wasn't a hyundai accent) anyway anything would be useful, car isn't under warranty so trying to stay out of dealership...

I have yet another issue with my Hyundai Accent. It seems to me that I hear engine valve knocking. Here tech. details:
- This happens around 1100-2000 rpm.
- The car currently has 11500 KM.
- 3 oil changes so far - using Mobil 1 - 10W30.
- I put in regular gas.
- No mods, only bug guard.
I drive slow - slow acceleration and I noticed sometime ago that there was a knock coming from an engine at about 1400-1700 RPM, however now I can hear it anywhere from 1100 to 2000 rpm. I can hear it very well when I drive along curbs and walls since engine sound bounces off it. I have automatic gear box and therefore I don't know how to test it further ( on manual I would have put some load on the engine by switching into high gear and pressing gas - make engine struggle a bit ). It might be noise from injector but I don't know. Also I don't know if Accent 2010 has self-adjusting valves or not.

After almost an entire year of trouble-free running (with the exception of replacing a ground strap), my 2009 accent decided to start bucking and shuddering again. It only does this when warmed up, runs perfect cold. In the last 16 months, I've replaced the plugs, coils, battery, PCV valve, and ground strap. Car starts with zero hesitation.
Strong battery and starter, consistent output from alternator. After @5 miles, the car stumbles on acceleration, and idles sporadically. While looking at it tonight, I noticed a few exhaust brackets under the car had broken, and the flex section of the intermediate pipe had torn open. Could this presumed exhaust leak be causing the crap running performance?
My "exhausted" brain thought it could cause the O2 sensor to misinform the ECM, resulting in the P0300 code I pulled...

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?

Bought my first Hyundai, a 2013 Accent last Saturday. Love almost everything about the vehicle.
It is equipped with the EcoBoost which I can turn on and off.
Noticing when I accelerate almost every time there is some initial acceleration and then a noticeable power loss. It's much worse when I'm accelerating through a turn.
Honestly it's hard to tell too much of a difference with the EcoBoost and AC off.
Also noticing the car really surges at times with the cruise control on. Obviously if I hit an incline it's going to boost a bit, but sometimes even on very minor inclines or straightaways the RPMS just fluctuate more than they seem to need to.
Wondering if this is normal for this engine and something I need to get used to. Coming from a Honda Civic I didn't experience this consistent power loss / fluctuation.
