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 RepliesI have a 2008 accent with about 95k miles on it. I recently took it in to have the oil changed and the mechanic suggested I get a tune up and said my spark plugs needed to be changed. I didn't opt in for the tune up that day and I'm now noticing more problems with the vehicle. At first the car struggled accelerating at about 35-45 mph, but once it reached above that speed it ran fine. More recently the car has really struggled accelerating after it had come to a stop. Today I came out to start the car and it took a couple tries to get it to kick over. Once the car was on I could rev it up but when I put it in gear it struggled to get to 10mph and that's with the gas pedal pressed all the way to the ground. I let it set and came back to it about an hour ago and added transmission fluid, because it was low. The car started a little better, it wasn't shaking as hard, but it still struggles accelerating and won't push pass 30mph. When parked I can rev it all the way up, when I take my foot off the gas the car does threaten to cut off, but it only has once. I'm not sure where to start.
View 13 RepliesI have a 2009 Hyundai Accent with 52000Km (32932miles) The car was parked since 2011 and now when I started it, it started really rough and would not accelerate (it would die if i pressed the acceleration pedal) but now after multiple attempts the car sounds like it wants to start but it doesn't unless I press the acceleration pedal when starting the car then the car revs to 2000rpm and dies within 1-2seconds,I also hear a odd sound from the intake its like a loud rumble. So far I have tried
- changing the spark plugs
- changing the coils
- checked spark
- cleaned intake manifold
- cleaned throttle body
- replaced PCV valve (because originally there was alot of oil in the intake)
- checked if fuel pump is pumping gas
I also checked the engine codes and there is a code for crankshaft position sensor abnormal -P0336 I unplugged the crankshaft sensor and the car wont start at all further more I also checked if it was sending the correct rpms with my obd tool and it seems like it is ...
My 2008 Accent has a manual trans and 4-Cyl, 1.6L. It had some bad fuel 4 weeks ago, and filled the tank with 97 to clean it back up.
I was driving and came to a stop sign - the server stopped and wouldn't start up again. I was worried about the fuel pump, and ended up replacing the whole thing (under the passenger seat).
I have tested the following:
- When cranked, the bottom of the spark plugs are wet (so gas is getting to the plugs)
- When plugs are pulled out, they spark against the block (so spark should be getting to the cylinder).
The car still doesn't start, and the cranking sounds 'off'. I can't exactly describe what's wrong, but I've had it for six years and it doesn't sound right.
Car died while driving home. Now it wont start. The tow truck driver that towed me home swears that the timing belt is out. Car makes spinning noise when I try to start it. I plugged in my code reader and got P0342 Camshaft Position Sensor Circuit Low Input. Not sure where to go from here. Do I replace the sensor or take it in to have the timing belt done? 109,000 miles.
View 7 RepliesI'm having an issue with my 08 Accent GS. It is very difficult to start, but only after fueling. Any other time, the car starts without any problems. I have tried to simulate the issue at home by taking off the gas cap and replacing it, but it didn't have the same result.
View 8 RepliesI have an 08 accent gls hatch that stalled the other day and wont start. Replaced the crank and cam sensors as well as the map and purge valve. Now it sputters and stalls with the fuel pump jumped. Has spark ans well as fuel at rail. What am i missing- no engine codes...
View 8 RepliesMy accent won't start anymore. When I turn the key, I hear a series of clicks, but the car won't start. When I put the key in the ignition, lights/radio/wipers all work fine. It's a 2008 manual car.
View 3 RepliesThe timing belt broke in my gf's '08 accent recently and I decided to have a crack at replacing the belt after getting a quote for $900 from the nearest mechanic (with no guarantee it would fix the problem).
When re-aligning the cam and crank to TDC, I wasn't sure if it mattered which revolution the crank was on (ie. 1st or 2nd revolution) when putting everything back together. I tested rotating the engine with the new belt on slowly to make sure there was no contact and everything seemed ok.
So basically now everything is back together, tried starting it up and it won't start and now i'm wondering if it would make a difference or not if the crank was rotated 1 additional revolution. Otherwise there is more significant damage.
I 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.
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?
View 5 RepliesMy 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 RepliesI recently installed an AEM intake on my 08 Accent GLS with an automatic trans. After I installed it I noticed the trans shifting funny into 4th gear. Before shifting into 4th the RPM's will drop accelerate a little more then it will shift into 4th. I've thought about switching to Royal Purple trans fluid to see if it will fix the problem.
View 11 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/
So, 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.
