About 2 months ago my 2008 accent 3 dr hatchback started to do what i can only explain as a hiccup while idling and also when first hitting the gas. But I didn't have. Check engine light on. So I changed the air filter and put techron a fuel injector cleaner in it stopped until last night so I am replacing the spark plugs. Is there any thing else i should look in to replacing?

I have a slight issue. A few weeks ago, I put some "STP" style fuel injector cleaner into my gas tank. Either A) It cleaned everything really well and clogged my injectors, or it turned into gunk and possibly clogged something else up.
Ever since that day, my issue is that the car "stutters" very slightly. When idling, it'll "hiccup." When I'm doing normal driving, 55-60mph at 2k RPM, It'll almost feel like a transmission slip.
I've went and replaced my Fuel pump, filter, and now I've done half a can of seafoam through the brake line power booster (vaccuum) straight into the engine, and the other half into my oil for further cleaning. I also applied Seafoam Deep Creep into my throttle body, just for further maintenance.
Ever since then, everything has been running noticeably better, and I've had a huge increase in gas mileage, but there's still a slight hiccup that occurs during idle and driving.
I change the oil /filter, plugs, wires, air filter on a regular basis.
I also had to change the MAF at one point in time, as it died and the car wouldn't start at all.
Next thing I'm thinking about doing is changing the plugs / wires one more time (it's been about 5 months since my last change) just to see if I bought a faulty plug.
The car was put on a computer and the only error code that came up was one about my check engine light being out.
My 95 Concorde, when I am at a stop, will sometimes hiccup/sputter while idling. It will also sometimes do it when I push on the accelerator when speeding up from say 35mph zone up to 55 – it will do it a few times and then smooth out. But, when I a get to a stop light, it’ will hiccup/sputter a few times – a couple of times it seemed real bad and the car seemed to shake.
When it does this I don’t notice any movement in the RPM needle and seems to idle normally; It’s never died and starts just fine.
The muffler needs fixed – has a hole or something. I was thinking of getting an oil change, replace the air and fuel filter, first.
Not so much hitting pot holes but hitting dips in road I get a noise up front like hard plastic cracked and hitting edges, had the front end checked all fine and he changed the sway bar links said sloppy, still noise, I went under found the front pipe bracket broken so I clamped that, still noise-could it be the strut boot? Doesn't seem to be the shock bushing they seem tight but can not really see them and the upper shock part seems secure. 2011 accent 60k miles. Where I could look next? The plastic around the wheel well is cracked but I don't think all that noise is coming from that, but the next warm dry day I will try to snug that up.
View 1 RepliesMy Mother has an accent 1.3 glx on a 55 plate the problem she has is that every time she accelerates the car does a hiccup (her words not mine) the engine management light comes on and off and then its fine.
View 3 RepliesMy 2001 1.5l works fine when cold however once it reaches temperature it will hiccup and then stall! It WILL NOT fire up until it gets cold again. Usually happens when we are coasting to a stop. I'm not a mechanic but can am mechanically inclined. I brought it to Autozone and had the computer codes sent (yes check engine lt was on) One code was a fuel lean code. Cannot recall the exact number. When it act up it sounds like there is either no fuel or no fire. I cleaned the mass air sensor and put fuel treatment in it and I replaced the fuel gas cap.
View 1 RepliesI have a 2006 Hyundai Accent that won't start. My wife was driving home the other day, and while she was sitting at the light she said she noticed a sudden change in the idle. She said the car starting shaking a little and idling really rough. When she tried to accelerate after the light changed, she said the car sputtered and would barely go.
She was only a couple of blocks from the house so she continued home. The car made it the rest of the way home, but she said it never went over about 5 mph even though she was pressing the accelerator as she would if she were going about 30...the car just never responded. When she pulled into the garage the car died as she was turning. Now it will crank but it won't start at all.
I tested the crankshaft position sensor with my multimeter and it was bad. I bought a new one and put it on, and I tested it immediately. The new one works, so I plugged everything back in and tried to start the car...nothing, just cranks and won't start. It's getting fuel and fire as well (tested both), but it's not hitting on any of the cylinders.
My 2010 Accent has been stalling intermittently, always when I am idling. I'll be at a stop light, and it will stall, and then it usually starts right up again. It is almost always the same stop light on my way to work, like clockwork, and likewise on my way home from work. Also, sometimes right after this stalling event, the motor will be a little rough on the highway, sputtering like it's not getting gas very well, but then it evens out after a while.
Yesterday for the first time it died and wouldn't start again. I suspected my fuel pump had gone out. I had it towed to a repair shop, but it started just fine for them and they can't re-create the problem. It doesn't give any computer codes at all.
I have a 2010 Accent GS, 5 speed. While sitting at a red light, or even rolling in neutral, the car will just die out. 90% of the time, the car will start right back up, no problem. A few times, though, it would not start right back up.. I put my flashers on, and just keep trying. It eventually starts up again, as people honk and get angry at me, but once a nice guy pulled over and offered to give me a jump and it started right up. I drove right to an autoparts store and had them test my battery, starter and alternator. All came back perfectly fine. There is no check engine light coming on when this happens. There is no code produced. A knowledgeable friend recommended i just change the battery since my car is 6yrs old, 104k miles. He said he had a similar experience and just changing out the battery solved everything. Well, i just did that and it stalled again. That obviously was not the problem.
View 8 RepliesTwice today my car stalled out while idling. Once at a left turn red light and once in the drive thru. The first time it restarted after about 10 minutes. The second time it restarted after about 2 minutes.
Car is throwing cod P0339 for Crankshaft Position Sensor A Circuit Intermittent.
I did some reading up on this on the forums but didn't do much about it. I just tried wiggling the wiring and all that when idling, didn't notice any roughness or stalling so.... may not be a connector issue.
Anyhow, planning to take it in for diagnosis and repair as it's really not derivable the way it is.
Actually this is the first time ever the car has given me engine trouble of any kind. just passed 90,000 miles. Shucks, streak broken.
Whenever I turn on my A/C and the car is in idle, it will turn off. Then I have to put it in park and turn it in again.
View 1 RepliesSo recently my 2009 hyundai accent has been idling rough, and has been very sluggish when accelerating. Usually the rough idling is the worst when the car is first turned on and tends to tone down as the car keeps running. I had the codes red and I believe it was C0302 C0303 C0304, saying that cylinders 2-4 were misfiring.
I replaced the spark plugs which didn't fix the problem, although cylinder 4 did have a small amount of oil above the spark plug and a little bit more below the spark plug, I am not sure if that means anything useful or not. I don't have a way to check the coils directly but I swapped coil 2 with coil 1 and checked the codes again and it was still cylinders 2-4 misfiring, so I would imagine that means the coil isn't the problem. I then tried spraying WD-40 around the vacuum tubes, and if the intake manifold is on the back of the engine I tried spraying it around that gasket as well, but I didn't notice a change in the idle speed.
At this point I am not entirely sure how to proceed, from what I have read the issue causing a misfire would be either there isn't a spark, which seems unlikely at this point, or the mixture of fuel to air is wrong. That is the part I am unsure of how to diagnose/
When idling and when first start to accelerate it feels like my car is hiccuping. I don't know what the issue is. I do know When i first bought The car about 8 months ago the oils Got wet when The dealer power washed he engine.
View 4 RepliesSo, I have a 2011 Hyundai Accent. It drives great. Until recently.
My wife noticed that it was cranking a little longer than usual before starting. Then, one day, I noticed it. So, I stopped the car and restarted it to see if it would happen again, and listen more closely. But, all ti did was crank.
I became upset and went in to do some research and make some phone calls. I came back out and voila, it magically worked fine again. Weird, I thought.
A few days later, no incidents. We go to the grocery store. On our way out, it cranks longer. This time I'm not going to restart it, I think. So, I start driving and everything is great. Except...it suddenly wasn't accelerating. It felt like it was in neutral for like 100 feet or so, then back to normal. We're making plans to take it into the shop at this point.
The next day, we go out to get coffee. Car drives great. On our way out, no problems. We stop at the red light, and it stalls. I have to push it into a parking lot and call the tow. Strangely enough, it starts again ten minutes later, and runs fine.
The stalling and being unable to start for tenish minutes phenomenon has happened three times.
We took it to the shop, it actually did this as I was filling up gas--stalled. I pushed it into a space and waited a few minutes, bam, it started up fine. The mechanic told me that the engine light had been reset. He couldn't figure it out. Said everything looked great.
So, the run down is this:
-My car stalls when idling, but only after it has been driven some, stopped, and restarted without a lot of time passing--like when you're coming home from the store or something, after it sits for 30 or 40 minutes.
-Once stalled, it will not restart again until a few minutes have passed --something like five to ten minutes.
-There is no check engine light. Fluid levels are good. Connections and whatnot, according to the mechanic, looked good.
-When it stalls, all the electronics stay on and work. The oil light and engine light pop up (like this key is in and turned part way), then it all goes away when the car restarts.
-the computer says that it was reset after it does this.
In the process of rebuilding a 2007 Accent where the timing belt broke while idling.
Pulled the head, ran a "water test" on the valves (put spark plug in, pour water on the valves and see if it comes out the exhaust/intake side) and found that only 2 intake valves were belt. Also shut off all the lights in a pitch black room, shined a flashlight in the intake/exhaust and didn't see any light leak from any of the cylinders except the one with the 2 bent valves.
Does this make sense? I would assume since 2 cylinders are always TDC at once, at least 4 valves would be bent.
Lastly, before rebuild I'll be replacing the 2 intake valves, all the valve stem seals, intake manifold gasket, exhaust manifold gasket, head gasket, head bolts and valve cover gasket. Anything else I should replace on the head? Trying to keep costs down as much as possible.
To add: Pistons have no damage on them, there are no marks of the valves hitting the pistons. The timing belt was replaced after it broke and the engine still ran however it ran rough. Compression test was done on only cylinder 1&2, 1 had 60 PSI and 2 had 0 PSI. Compression test was also done by just rotating the crank with a socket since I already had some of the engine disassembled.
So I bought my accent used a couple months ago. It is a 2007 SE 3dr 5spd manual. It ran nice during my test drive and the price was right so I bought it.
Now I'm wondering if there is any way to find out the service history on the car...at least the major one's (30k, 60k)?
I ask because recently the engine was idling a little rough and it threw a P0302 code so I changed the spark plugs and holy-cruddy-deposits-batman those things were black. Gapped the new ones and popped them in and its a noticeable difference. My CEL keeps coming on and throwing a P0496 code as well, virtually once every tank of gas. Its not the gas cap so my next step there is to check the PCSV and hoses.
With these little problems, it makes me wonder about any larger issues. I know the timing belt on these things is supposed to be replaced at 60k. Additionally I would be willing to bet that my ECM software is out of date. Would Hyundai have records for any of the big maintenance milestones since they are required for warranty work?
How much does it cost to have a dealer check your ECM software and update it if needed?
Recently my car, after I put fuel into my car, my car won't start unless I apply the gas and then shift it into gear. I thought that perhaps replacing my spark plugs would fix this problem since it is about time for a tune up on my 2010 Hyundai Accent. About a week after changing the spark plugs I now have an error code that states that Cylinder 2 and 4 are misfiring and it is causing my car to shake while it is idling or speeding up. Also it is much slower than before to get it started from a stopped position.
View 11 RepliesHad my SE for nearly a year, love it, but noticed that when I hit a bump or pothole in the road with the right wheels, the car moves to the left and I to correct to center again.
It does not happen for the left side (or maybe I don't feel it as much).
I have a 2006 sierra 5.3. This has happen twice to me now. This morning it was probably around -5 degrees out started my truck with remote start and it started fine. After running for 15 mins I got in it to go to work. When went to pull out of the driveway I noticed when hitting the gas my headlights getting brighter and then dimmer when not hitting the gas. When I looked at voltmeter gauge and when not pressing the accelerator it was about 12. When hitting accelerator it would go up to 14. It did this for about 15 mins or so stopping and going.
On the way home today it didn't fluctuate. When I got home I tested the alternator with volt meter. It was reading 15.3 volts. From what I read on the internet it says the fluctuation is normal and so is the 15.3 volts. I read 2005 trucks and up have regulated voltage control. Even talks about the gauge fluctuating in the owners manual. I had the battery and alternator tested both tested good. Alternator does have a little noise in it when spinning the pulley by hand. I'm just not convinced that 15.3 volts is normal. The battery isn't original it had been replaced by the previous owner.? Is my alternator possibly going out.
So... I had the hood open and when i pressed the gas it makes a short hissing noise of some sort... I'll try and get a video tomorrow... it only lasts for about 1-2 seconds not sure if its just induction noise...
View 11 RepliesMy 2006 V6 Camry XLE feels like there is a delay between hitting the pedal and the car accelerating. I also notice it bucks (changes gears at the wrong time) occasionally when pressing the pedal than backing off of it a little. The hesitation has always been there but lately its been really bothering me because I drove someone else car (Hyundai Sonata 4 cylinder )and felt how smooth it accelerated and how responsive it was at lower speeds. I know this car has drive by wire which probably has something to do with the problem. How to alleviate this issue? I don't think there's anything mechanically wrong.
