Accent LC (2000-05) :: Odd Vibration And Belt Squeal Intermittently At Idle
Dec 3, 2016
I am posting about a cam sensor code and alternator belt squeal.
Yesterday after getting in from a 600 mile drive from salt lake to eastern Oregon i took a look at the car to put some fogs in and clean it up a bit. It had always had some odd vibration at idle and belt squeal intermittently at idle. I pressed down on the alternator at idle and the vibration noise went away. So bam. Found that.
The nut on the square head mounting bolt holding the alternator was missing. So it was kind of just flapping around. Replaced the bolt and put a lock nut on. Problem solved so I thought.
I'm still getting belt squeal. And i think that its out of alignment. It looks like the pulley side of the alternator is closer to the engine block than the other side. Is this adjustable? Is the bushing on the mounting side worn out to the point of movement? Is this fixable?

Changed the timing belt and water pump this past weekend. I made sure the timing marks aligned before I put the belts on. They were still aligned after turning the engine by hand and still aligned after taking the car out for a test drive. I did not notice rough idle when I started the engine in the garage nor did I notice a rough idle during the test drive.
A few days later I am now noticing the car will idle roughly when I come to a stop. The idle will get rough enough to gently shake the car. No engine light and no unusual noise from the engine.
I am going to check the timing marks again tonight. I suspect the belt may actually be off by one tooth. I have driven over 100 miles since changing the belt so I don't believe it is off anymore than one tooth or else I presume I'd probably have already broken down or been hearing unusual noises.
Furthermore, I do not seem to have any loss in power. I still have good acceleration and no roughness unless at idle engine speed. I do, however, run rough at higher speeds (75+ mph) on the highway, but this was present before the timing belt change. Unfortunately the car does not have an RPM gauge.
Having said all of this, are there any other possible reasons why I might be idling rough now?

My car is standard 5 speed transmission, when my car is running my idle varys between 800ish to 1500 intermittently within seconds and if I don't drive it after starting the car it will stall on me (in neutral) after the rpms go up and down about 9 times.
The thing I found is if I disconnect my idle air control valve attached to my throttle body it stops the jumps in rpm. I have tried replacing the valve with one of my friends control valve Hyundai accent 2004 that works and fits perfectly on his doesn't work on mine. Right now I have my idle air control valve disconnected at the moment but i want to fix this issue because my rpms are at 1300 at idle.

Been having a fair bit of trouble with my accent, at first my car sometimes would hesitate on acceleration in 1st gear. Now it has a rough idle and the engine just completely cuts out at random. It does however start straight back up. It makes an odd noise whilst idling almost like a misfire from the exhaust. On start up it blows a lot of white smoke. And when you do get driving it is really jerky. It's been serviced every 5000ks. I've changed spark plugs, map sensor and throttle body sensor, put a fuel injector cleaner through and still no improvements. It's been booked into the mechanics for next Tuesday.

Motor has been stalling intermittently since May. Finally had the fuel pump replaced last Friday (8/17/12). have been driving the car back and forth to work since then with no problems until yesterday. Made a run to the local convenience store and the car was shut down for about ten minutes. Came back out and car would not start! Gave it about 10 minutes and then it started again. Got it into the garage and let it run for awhile and it stalled out. Got the check engine light (a first for that) so swapped the fuel pump relay with one of the same part number. Fired right up and did not stall out.
Also, check engine light went out on its own. Swapped relays back to original positions, motor started right up, stayed running and check engine light went out on its own. What could be causing my problem? Since check engine light came on then went out on its own, would there be any trouble codes to read? One other thing, original relay has pinkish residue on the pins. What could that be about? First time poster so I hope what I have typed out makes sense. 2003 Accent 4 door with 1.6L DOHC motor. Approx 79000 miles.

I have a 00 Accent with 132k miles, I replaced the motor a year ago with a correct 2000 Hyundai 1.5 with 50k miles. I replaced everything that I could at the time, timing belt , starter, water pump, and clutch. It has been running fantastic getting 40 miles per gallon with zero problems , However in the last week I have noticed a rough idle that seems to miss with a vibration that it didn't have before. I have a noticeable loss of power and torque. My miles per gallon has also dropped to about 25 mpg. My check engine light is not on. I will check the plugs and change the air filter today but I would like to know what else could be causing the problem as I am not really sure what to check.

My wife and I recently bought a 2005 Subaru Outback 2.5 XT with an automatic transmission. Last week, we had the timing belt changed by a mechanic I've gone to for the past four years and trust a great deal. He changed the timing belt, drive belts, water pump, pulleys, tensioner and a few hoses, and everything seemed to go off without a hitch. After picking up the car, though, we noticed that the idle seemed much rougher than it had in the past. We can't tell if it's also rough during driving, or when the car is in park or neutral, but there is definitely considerably more vibration when the car is stopped in drive and idling--you can feel it throughout the car. I haven't noticed it until the car has warmed up.
I asked my brother, who is a mechanic in another state, if he had any thoughts, and he said it could be that the belt is off a notch, a vacuum leak or an unplugged sensor. I brought the car back to the mechanic today to see if it he could fix it, and he said that the CEL would be on if it was a vacuum leak or unplugged sensor, and that the car has an automatic idle that the belt change would not have adjusted. He asked if the vibration was getting any better, since when the battery was unplugged it would take the computer awhile to relearn the correct idle, but we've driven it a few hundred miles and it hasn't gotten any better. I left the car with him to take a look at it, but he just called and said he couldn't find anything wrong.
I want to chalk this up to us imagining something, but we both have no doubt that there has been considerably more vibration at least when the car is idling since we picked it up after the timing belt change. Is there anything else that it could be or that I should ask my mechanic?

I just changed the timing belt and everything runs great. I pushed the AC button and no light came on. I checked all the fuses and they are good I took the H and L caps of and tapped the pin and there was air blasting out. Don't know what it could be? All I did was loosen the compressor and remove the belt and put it back on.

I just finished replacing my timing belt, water pump and all belts. I made sure to double check the timing marks lined up via this pic:
Timing belt diagram
I put everything back together and no go. I am not sure what to do now. Should the crank sprocket pulley be in a special starting position? I see is has a "1" engraved on it.

The timing belt went out at idle while making a turn. I changed the timing belt, but when cranked you have to pump the gas to keep it running and it is really rough running with a smell of gas when you turn it off. On the last run it backfired slightly. There is no knocking or pinging. And have triple checked the timing. Could improper torque on the crankshaft bolt cause this or failed ignition coils?

2008 ES350 with 170k miles. My wife drives the car almost exclusively but we went on a road trip and I had the opportunity to drive it for a few hours.
I noticed at idle there is a chirping sounds from the belt area like it could be a water pump or another pulley going out.
Other data points:
At speeds over 80mph I feed a vibration in the steering wheel. we are 1k over getting the tires rotated so that may clear this issue up.
low speed in a parking lot I had the wheel at full lock turning and it felt like it "slipped" and it made a noise. This made me think the power steering pump could be what is going out.
I need to check the fluid levels tonight and see if either is leaking ( there is nothing on the garage floor)
Are there any good DIY's for a waterpump or power steering pump replacement? Once I diagnose the problem I would like to fix it myself.
Are these common issues with the ES350?

Since the weather got colder I've been getting really loud, squealing belt noises. They happen mostly when I turn on the car. They sound like when I had an old Altima and turned on the A/C the belt would squeal. But the sound happens even with no air turned on or defogger turned on. And it happens sometimes when I make a really sharp turn around when I first start the car. After it's warmed up I generally don't hear it. Also, sometimes having my foot on the brake will change how long the sound lasts for. I'd like to know what belt this would be and if just WD-40 should be used for now (or some type of belt dressing) OR if it's detrimental not to get work done on it. Also let me know if I'm able to tighten it myself or if that's better left. I replaced a valve cover gasket a few months ago so that's about the extent of my abilities at this point.
It's a 2003 Hyundai Accent Automatic...

My mechanic just did the timing bet, water pump and other belts. Also changed the tensioner.
Car runs fine and everything seems great until I get to a red light. The engine sounds louder then before. Not very loud but its louder and maybe a very slight vibration, not sure yet. No noises while driving, seems like its running the same or better then before. Runs fine though

Awful belt noise that erupts during cold starts. I realize that this usually means a replaced belt. I want to know how to go along diagnosing which belt and then how to replace it. Here's the symptoms:
1. Awful belt screech when turned on, goes away within 20 seconds
2. Belt noise comes back when turning the wheel to back out of a right driveway
3. The STEERING WHEEL feels like it has no power steering WHILE the screeching is happening.
4. The headlights (when on) dim for about 3 seconds
5. All these symptoms happen when the temperature is below freezing and it's a cold start.
How is the belt screeching connected to the steering wheel being tough I turn?

The steering on our 02 Accent has been becoming more and more difficult. The belt on the AC compressor snapped off recently. Could this missing belt be causing a problem with the power steering belt? The power steering belt is now making a squeaking noise.

I bought a 02 accent base model hb 5 speed 109k miles for a winter car (have a mustang in garage.) It ran good until tonight when the timing belt snapped. I know this because while driving it made some ticking noises and then shut off and when you try to start it the noise that comes indicates no compression so the belt must've snapped and bent the valves.

I have a 2002 Hyundai Accent with about 222,000 mikes on it. It runs extremely smoothly, but I've had problem after problem with startup. My clutch sensor was loose for a while, replaced my starter, replaced the ignition coil, everything that could stop the thing from starting up has happened. Finally for the last couple weeks, the car has had these spells where it will crank forever and not start, like it did when I replaced the coil (I did that again just in case, not the problem). These spells last varying mounts of time.
A few times it's started up in minutes, and two times now it's been out for at least a day. I've checked everything and it seems to not be getting spark when it's not starting. I'd really like any insight to this. I'm considering changing my crankshaft position sensor and camshaft position sensor, but I can't even find those on my engine. What could be causing this? I really need a car that will start up and is reliable. It should be noted that the car USUALLY starts fine. This only happens about once every 5 or 6 days.

I have a 2004 Hyundai Accent. The factory alarm goes off intermittently and the central locking engages at times without warning.
I took it to an Auto Electrician who checked it over but couldn't work out the problem. So i took it to the dealer who said it was most likely the bonnet sensor. I wasn't convinced but they went ahead and charged $150 to diagnose and adjust the sensor and said everything would be fine.
Within one day of being 'fixed' the problem has reappeared. I am getting sick of disconnecting a battery terminal every night....

I have a 2004 Accent GS. It is an automatic. I have had it for almost a year.
In early November, the check engine light came on when the temperature dropped drastically and it went off when it warmed up a bit about 3 days later. Since then it seems to come on randomly and stay on for a few days then go off (usually around once-twice a month). Then in late December I noticed that the car had trouble starting after I refueled it, the first two times I though it was because I had let the fuel get down too much. Now every time I fuel up it does this. But just the first time turning on the car and no other time after that.
The check engine light had not come on again for almost a month, and then about a week ago it came on again. I double checked all the fluids and the gas cap but that's about as far as my knowledge of cars goes. When the light has come on I have not really noticed any handling differences. However since I need to put the car through an inspection very soon it is now concerning me a bit more. What could be causing the check engine light to go on and off?
