Hyundai - Elantra :: 2008 - Distinct Hesitation When Accelerating From Speeds Of 10 To 15 Mph

I have owned this car from new and it currently has 32k miles. The only fuel used has been 85 octane or occasionally a tank of 93 octane. There is a distinct hesitation when accelerating from speeds of 10 to 15 mph and I do not believe it is due to the transmission shifting. I did move to my current state,California, from Pennsylvania and was told by my local Hyundai dealer service department that because California has a different gasoline formulation from most other states as well as a summer and winter blend to reduce emissions it is recommended to run a bottle of injector cleaner every 15k miles.

Gasoline - Hyundai - Elantra - Transmissions - Clutches :: 2002 - Losing Power When Climbing Hills

Our 2002 Hyundai Elantra is having issues. It shifts fine, no need to double-clutch. It stays in gear. Doesn't grind or anything crazy like that. It does seem like it isn't getting power to the drivetrain, and is having trouble climbing hills. This all came on very suddenly. Hubby thinks it's the clutch -- I think it may be the bushings. Though now, I'm wondering if it's something else? Since it's not having trouble shifting, should we be looking at the fuel system? Sensors? Engine seals?

Hyundai - Elantra :: 2001 - Gas Cut When Accelerating Sometimes, Very Often Lately

My problem is gas cut on my Elantra 2001. Here is how it happened; Last week I filled up my tank with regular gasoline then added middle quality gas this time. I always use middle quality gas but once I made a mistake and filled with regular. Then my reliable elantra started stumble and cut gas few times in a day. What would be the problem?

Hyundai - Elantra :: 2004 - Jerks When Driving Uphill / Accelerating

I have a 2004 Hyundai Elantra with 130000+ mi on it. The current engine has 96000+ mi; the original was replaced because the previous owner allowed it to overheat, blew a gasket, and apparently warped the engine itself.

I have owned this car for about 6 weeks now. The car was driven roughly 160 mi from where it was purchased to my residence; no trouble on that trip. However, within the first few weeks of owning it, the car started making a squealing noise when I turned the steering wheel. I took the car to a mechanic and had the belts adjusted. This eliminated the squealing, but I was also told that the CV boot needed to be replaced (they asked if I had been hearing a clicking noise when turning, which I had but had thought nothing of), so I also had that repair done. Problem solved. Car seemed to be running fine.

Okay, on to the current problem. Something else I had started to notice, before I had the belts adjusted, was that it seemed to hesitate a little when going up hills, and sometimes when accelerating. It was a small thing, and I attributed it to my driving style (which probably isn't the best) and the fact that my area is very hilly and the car might be having a harder time with that. Well, this problem has gotten worse; I can definitely feel the car jerking, especially when accelerating (very noticeable when going uphill). The problem also seems to be worse at lower speeds, but I'm not entirely sure that I've nailed that down.

One thing I noticed is that it seemed to become much more noticeable after the last time I gassed up the car. It seems like it's getting worse as the fuel is used up, but that's probably just a consequence of using up fuel as I drive and I'm just looking for connections where there aren't any.

Hyundai - Elantra :: Grinding Noise When Accelerating And Sometimes At Lower Speeds

My 2007 Hyundai Elantra SE (Automatic, 69,400 miles) makes a grinding noise when I start to accelerate from 40 mph. I sometimes hear a noise that sounds like an airplane wheel being activated when I'm driving at lower speeds driving around town. Could this be the transmission? Who should I take the car to?

Hyundai - Elantra :: 2004 - Relatively High RPMs When Accelerating With Sluggish Acceleration?

,I have a 2004 Hyundai Elantra (stick shift) with about 104k on it. Was running absolutely great till about a month ago when I noticed that it was beginning to accelerate quite slowly. If I pushed it and got the RPMs up really high it would still pick up, but still not great performance. Also after pushing it a little hard there was a faint burning or smoke smell. Note, once it is up to speed say 60 or 70 it has no trouble maintaining such speeds. It just takes a while getting up to them. And if I really need to step on it the RPMs sky rocket with no real immediate increase in speed.

Hyundai - Elantra :: 2002 - Rough Idle And Misfire When Hot / Intermittent Hesitation When Accelerating

2002 Hyundai Elantra GT 2.0L 140k miles

Symptoms:

- Intermittent rough idle when hot, slight shutter, surges between 700-800rmp
- Intermittent hesitation when accelerating, cylinder 2 misfire when hot and under load
- Misfires in all gears under load, mostly when under 2000rpm
- Code P0302 when scanned, no other codes
- Symptoms appeared suddenly, not gradually over time

What's been changed:

- Replaced spark plugs, little or no improvement. Old plugs looked worn, but generally in good shape with no significant deposits.
- Cleared code and swapped injectors between cylinders 1 and 2, after test drive P0302 code came back, so it seems that the injectors are good. If the injector were bad I would have expected the misfire to change from cylinder 2 to cylinder 1.

Inspection and Testing:

- Ignition System Testing
- Spark plug wires and primary coil are within specification.
- Secondary coil resistance is high on both packs. Could this be causing a problem with just cylinder 2? Is it worth replacing?

Spark Plug Wires: Specification: 5.6 Kohm/meter +- 20%Cylinder 1: 2.49 Kohm (Longest)Cylinder 2: 2.03 KohmCylinder 3: 1.64 KohmCylinder 4:1.36 Kohm (Shortest)
Primary Coil: Specification : 0.58ohms +- 10%Actual: .6 and .6
Secondary Coil: Specification: 12.2 Kohms +- 15%
Actual (Cold): 16.03K for Cylinder 2-3 pack and 15.94K for Cylinder 1-4 pack
Actual (Hot): 18.54K for Cylinder 2-3 pack and 18.44K for Cylinder 1-4 pack

Air/Fuel System Testing:Fuel system seems to check out. I do not believe the problem is fuel related. There are no obvious cracks or leaks on the intake manifold. A good spray of Carb cleaner all around the manifold causes no change in idle. I might try propane later. No obvious vacuum leaks.

Fuel Injector: Specification: 13.1-14.5 ohms
Actual: Cyl 1: 14.9, Cyl 2: 15.3, Cyl 3: 15.3, Cyl 4: 15.7

Compression Testing:Compression is not great, but within specification. Could the slightly lower compression in Cylinders 2 and 3 indicate a head gasket leak between those cylinders? Could this cause a misfire in Cylinder 2?

Dry Compression: Specification: 145-218psi, <15psi between cylinders
Actual: Cyl 1: 165, Cyl 2: 155, Cyl 3: 155, Cyl 4: 160

Oil/Coolant/Tailpipe:

- Oil looks normal, not brown or milky
- Coolant looks normal and is full, no signs of leaking (coolant has not been changed in a very long time, could a coolant flush work?)
- Exhaust looks and smells normal from tailpipe.

Sticking valve? How would I check this? Bad sensor somewhere? Doesn't a bad sensor usually throw a code?

Ford - Gasoline - Pump - Mustang :: Idle Will Sometimes Get Really Low (below 1000 RPM) And Stall Out

When my 1998 Mustang has been stopped and started numerous times in a short period--say, like when you're running errands--the idle will sometimes (not always!) get really low (below 1000 RPM), and will stall out no matter how much gas you give it. It will then refuse to start for about 30 minutes. Then it'll start back up and run fine for another week until the whole thing happens again. The car runs fine in all other respects, and again, it's seemingly random, and only after the engine has been stopped and started several times. It won't for example, stall out first thing in the morning.

Subaru - Stall - Gasoline - Forester :: 2004 - Cylinders Misfire Upon Fill Up

I have an '04 Subaru Forester which sputters and stalls after fill up. It sends error codes for cylinders 1, 3, & 4 misfiring...I only have a 4 cylinder car - This only started Friday - a few days later and I'm really getting desperate. I screw my gas cap on, we check the connections...and we've read all kinds of random solutions that spread across the board.

Oldsmobile - Stall - Gasoline - Pump - Misfire :: 1998 - Hesitates / Stalls / Sometimes Backfires?

My 88 "Rosie" has been having problems for months. It hesitates, stalls, and sometimes backfires. This is an intermittent problem, though it is happening more often lately. I took it to local auto shop and their computer showed Rosie was throwing a misfire code as well as a lean code. I took it 3 months ago, and I took it last week, got the same codes. The lean code led me to check the fuel pressure. I did and while it should be healthy 48-55 psi, I got 48 for awhile then 15 PSI! Now I'm thinking fuel delivery. I started with the filter. Sure enough it was dirty. Weeks later, the problem persists. I replaced the fuel regulator (ok, mostly because it was cheaper than the replacing the fuel pump, which I really didn't want to have to do.) Still, no luck, so I finally caved and spent $200 and 12 hrs dropping the tank to replace the fuel pump. Guess, what? Still no dice. I'm still getting the hesitation and the misfiring. I haven't put the fuel pressure tester back on it (been busy) so I don't know if the pressure is still low or if these other things are even related. I thought my logic was infallible. Let's face it, there's a finite number of parts that control fuel pressure. I'm running out of parts to replace. Where did I go wrong? The only thing I can think of that could still do it is perhaps the fuel pump relay? I dunno. Would it work off and on or fail completely? I'd love to get some opinions on this.

Hyundai - Elantra :: 2008 - At Start Up Stalls Randomly

My daughter's 2008 Elantra starts fine and seems to be idling okay. But recently at seemingly random times the car will stall within a few yards after she starts driving from a cold start. She will start the car, start to drive and then all of the dash lights come on and the engine shuts off. So far she has been able to turn the key and immediately restart the car and then it is fine after that. The problem always seems to occur after she has driven somewhere, let the car sit for a couple hours and then tries to drive again. We took to our mechanic and they said there are no diagnostic codes and the fuel pressure seems good. They did identify some kind of voltage drop/issue with the mass airflow sensor and replaced it. But a day later the problem occurred again. Mechanic seems stumped. I'm very worried about my teenage daughter driving a car that randomly stalls.

Hyundai Elantra :: 2008 - Driver Door Randomly Locks Itself When Get Out Of The Car

My 2008 Hyundai Elantra likes to play KeepAway.

The driver's door randomly locks itself when I get out of the car. Just the driver's door. I have learned either to make sure the others are unlocked or to take my keys with me, even if it's just to pump gas.

Might this be some easily replaceable or resettable circuitry, or do I just have to live with it?

Hyundai - Elantra :: 2008 - No Visual Sign Of Remote Lock?

The only issue I have with my newly acquired '08 Elantra is that there is no visual signal that the remote lock signal has been received. When I unlock it remotely, I get a single flash of lights, but nothing of the sort happens when I lock it; if I'm close enough, I hear the click of the locks engaging. I find nothing in the owner's manual describing any of it.

Is this normal, or do I have some weird computer anomaly going on?

Hyundai - Elantra :: 2008 - Constant Sound And Mild Vibration On The Pedal

I have a 2008 elantra. It has 71600 miles on it. New brakes, & tires. 2 tires were changed year and 2 more the previous year. I have been hearing a constant sound and starting to feel a mild vibration on the pedal. First I went to a mechanic and he said I need to change the belts. Got that done, no respite. Next went to another, he said i probably need to get the wheel alignment done as the tires seem 'cupped' on the inside.

Went to the dealership, they looked at it said the same abt needing wheel alignment and asked me to change the timing belt!. Still same sound. Went to Sams club to look at the tires & they said check the brakes, tires are fine, it cannot wear out so soon and its not covered under warranty. Brakes got checked out as fine. Went back to Sams again and was told to check Suspension and Struts this time. Went to a mechanic and he gave me an all clear this morning! I am going on a road trip and don't want to be in an accident!

Electrical-wiring - Hyundai - Elantra :: 2008 - Accelerator And Brake Pedal Would Not Engage

On my daily commute in stop-and-go traffic, on a bridge, headed downhill, suddenly neither the accelerator nor the brake pedal would engage in my 2008 Elantra. Cars in front of me had sped up, then ground to a halt, and I was coasting downhill toward them, at a pace too fast for the handbrake to stop me. I couldn't downshift either (the car has automatic transmission, but shifting to low lets the engine slow you down). With nothing else to try, I shut off the ignition and then turned it on and, amazingly, all was back to normal. The dealer didn't find any trouble codes in the computer so they say the car must be OK to drive. But I don't feel safe driving the car. This might have happened and what I can do to fix it?

IS F (2008-2014) :: Paddle Shifters - Carbon Version Not Working?

So I bought the carbon paddle shifters that Khoa was selling from the first carbon steering wheel he got.

Having already replaced my OEM steering wheel with the flat-bottomed version, I was familiar with the process for removing what I needed to change the shifters over.

Everything went fine, and after checking all the connections were good, I re-installed the steering wheel, re-connected the battery, and took the car for a test-drive.

At first I left the car in auto, and tried using the paddles. Nothing. Flicked the shifter over to manual-mode, and it popped up I was in 4th. Tried shifting with the paddles to go up or down, but nothing.

I was short for time, so had to leave it like that for a few days.

I then removed the wheel again, and reinstalled my OEM silver shifters. Took the car out for another test-drive, and it works fine.

Khoa was kind enough to speak to the guys that sell these along with the very nice steering wheels everyone is talking about. They suggested I swap over the paddles so I keep the electrics of my OEM shifters. The paddles themselves are only held in with a gudgeon pin, which tapped out quite easily. The paddle itself slots in to a hole in a metal piece inside the plastic end pieces. Looks as if it simply moves up and down when you flick the paddle front or backwards.

I mounted the carbon paddles into my OEM electrics, and tapped the gudgeon pins back into place. I then re-assembled the steering wheel, check the connections, and re-installed the wheel. Re-connected the battery and took the car for a test-drive with everything firmly crossed.

Nothing!

The paddles won't work at all. Not up or down. I am so confused as to why they don't work. I can't see any differences between the OEM silver paddles and the carbon versions. Not sure what my next move will be. I need to try putting the OEM paddles back together, and see if they work. If they do, I am baffled as to what the fundamental difference can be between the two?

Elantra HD (2006-10) :: 2008 Stopped Accelerating Now Won't Start At All

About 2 weeks ago my Elantra began displaying the symptom of struggling to start after fueling. The check engine light came on with P0170/P0171 codes for fuel trim malfunction. Did my research and replaced the fuel pump. After this, the car struggled to start all the time until after a few days, while I was driving, the car struggled to accelerate and jerked like crazy trying to. Did more research and replaced the fuel pressure regulator. After this the car drove beautifully for about an hour and then again stopped accelerating, jerking like crazy and lost all speed. Error code P0441 Evaporative Emissions now was the only one on. I filled the gas tank (it had been low) and for another hour the car was fine and then the trouble started again. After turning it off the car would not start at all. Now I replaced the Mass Air Flow Sensor but that did not fix it. All the relays and sensors look good. What to do next. It still won't start.

Hyundai - Accent :: 2004 - Stall Every Time When Stopped And Idling

The Accent is a 2004 and it belonged to my parents. It is a 5 speed manual trans. and has about 100K. It runs fine except when stopped and idling it stalls. It starts right up again, but stalls every time it idles. My dad said it was something inexpensive to fix, however he could not remember what the part was.
