Accent LC (2000-05) :: 2004 - Constant Hissing Noise Coming From The Middle Of Engine Compartment
Jul 11, 2011
My 04 hyundai accent about 2-3 months ago acquired a hissing noise which seems to be coming from the middle of the engine compartment. The car only has 100,000 miles on it.
It is a constant hiss that only stops when the gas pedal is pushed initially. I have looked all over the car and can not see any fluids leaking at all. It is pretty loud and can be heard easily outside the car when the car is on.
I hooked up my obd2 reader and found these codes:
P0304-Cylinder 4 misfire (I notice it when the car sits at idle for about a minute)
2x P0121- Throttle Position circuit range/performance problem
2x- Evaporative emission incorrect purge flow.

Looking for some input on a recent "hissing" noise coming from eng compartment. It's only noticeable during initial acceleration, and sometimes at the beginning of gear changes. I am assuming its tubo and/or exhaust related, as I've noticed a strong exhaust odor in the cab as well. I wasn't under load when the problem started but i was under rapid acceleration. Not noticing any fluids or oils leaking. No warning lights have tripped, as of yet.

I have a 4 door 2005 Accent with ABS. I mainly drive in the city, and lately I noticed a squeaking noise that sounds like it's coming from the front right side (from inside the car); it is a constant noise. I pulled the brakes off both sides, the pads are fine, the rotors were a little rough (normal). Before I reinstalled everything I took some 80 grit emery cloth and roughed the pads and the rotors with it just in case there was some glazing.
The noise is still there and what concerns me more than the noise is the fact that the longer I drive the car the more gas I seem to need to apply to get the car to move.... not a huge amount but enough. Also, once I stop the car, there is a slight brake smell and the passenger side front tire area (brake) is crazy hot. Long story short; I would like to check to see if I have a stuck piston in the caliper, But I'm not 100% sure how to. Do I pull the pads off, push the piston in , watch how fast it goes in, and then compare it to the drivers' side? Or do I need to pull the caliper apart?

Yesterday I started feeling a constant bump coming from the middle of the vehicle... i can really feel it with with elbow on the console. The bumping seems to speed it up with transmission but it does continue when i slip it into neutral. I stopped by the dealership and they said "It's prolly some motor that in the middle of the car. It happens on a lot of touaregs"

I installed a Eurojet "Street" FMIC on my 2004.5 GLI a few weeks ago and ever since there has been a constant air hissing noise coming into the cabin. The noise has proven to be tricky to diagnose. It is loudest inside of the cabin and isn't audible under the hood. I boost leak tested the system and didn't find any obvious leaks. The sound doesn't appear to be boost related.
I don't seem to be loosing performance. (I've read a 2-3 psi drop is normal after FMIC install) The sound is constant and is faintly detectable even at idle inside the cabin. The sound's volume is dependent on the RPM's the engine is turning. The sound is constant whether the engine is on boost or vacuum. I can't explain this. My car isn't throwing any CEL's at all.
My mods are Revo Stage 2, 4 Bar FPR, 42dd TBE, Hyperboost DV, FMIC.

I have a 2004 Prius that has a ticking noise coming from the engine compartment It speeds up and slows down with the idle of the engine or the pressing of the accelerator. Appears to be coming from the passenger side (US). No diagnostic codes have come up.

I first noticed a strange noise coming from the engine compartment a day ago. I had left the car to sit in the sun for a few hours. When I got in the A/C was set to on and the system was on auto. I tested to see if the noise went away when I turned off the A/C and it did. I turned it back on and it returned. I know the A/C operates at different speeds based upon cooling needs and that it can get sort of noisy but I didn't think that it could/should get this loud. The system seems to begin working quickly and it does seem to put out cold air. If the noise is unusual do you think that it indicates another underlying problem in the A/C system?
Just to clarify, the ICE is not running in the video. The cabin fan is set to low and the temperature is set to low. The person in the car presses the A/C button and the cooling fans in the engine compartment come on as well as the A/C unit. The sound gets louder a few seconds in. Here is the link to the recording I made of the sound.

I hear hissing noise when my car A/C is turned on. I have show it in Firestone and the person is like everything seems fine. I do not understand the reason. But the A/C works without any issues.
The hissing noise can be heard everyday when i turn on my A/C initially and later in between i can hear 2 -3 times a day when i go to my office.

Having had bit of a disaster today (shutting keys in boot that cost me 85 quid, that's why you don't buy from people who've lost the spare key), I noticed back box mounts and back box are rusting.
Is it possible to swap the standard rear silencer for the 2005 1.3/1.5 accent with the twin outlet one for the coupe 1.6?
It looks very similar and the pipe bends look the same..? What a hissing noise is when in gear and running? Stopped it doesn't make the noise, and as soon as clutch is depressed while rolling it stops.. Had a new clutch fairly recently.

My wife's 2000 Hyundai Accent GL wouldn't start one morning. She tried to get a jump from someone, assuming it was a problem with the battery and apparently, they crossed the cables accidentally and melted the positive terminal of her battery. I replaced the battery about 2 weeks later and the car started up...a little rougher than normal, but it started nonetheless. After 30 seconds or so, the engine started to smoke. It seemed like it was coming from the rear of the engine.
After leaving it off for a few minutes, we restarted it and it was smoking again, this time from the front of the engine. I took a good whiff of the smoke and it's definitely gas fumes/exhaust fumes/I don't know. It seems like a pretty big coincidence for the battery to die and the exhaust manifold to become cracked all at the exact same time but I guess anything is possible. I guess my question is...is there something that could be causing this smoke and smell that could be linked to the battery being jumped incorrectly?

So I was sitting in my wife's car and hear a clunk while the car was in park sitting in the driveway. She said it had been doing that for a few weeks now. The clunk seems to happen every 4 or so seconds while idling and is coming from the engine compartment somewhere. There is also what seems to a hissing or sucking noise that sounds like it is coming from in the dash somewhere and also happens about every 4 seconds during idle. I really haven't had a chance to look into what the problem(s) may be or if they could be connected. I am really not sure what the clunking at idle could be. I think the hissing noise is a vacuum leak I could probably hunt down when I have a chance.

I have a 2001 1.6 DOHC Accent the engine has been making a lot noise coming form just the back of the head it kinda sounds like a diesel. I pulled the valve cover off and turned the engine over by hand. I noticed that cam chain has a good amount of slack in it. Is there a tensioner to take slack out of the chain? If so can I adjust it? If not how do I replace the chain?

So I had all of my belts changed including timing belt and tensioner pulley as well as an oil change. After, I noticed a weird pulsating grinding/wining noise coming from the engine bay. It only can be heard once the car is warmed up. (It is much louder in real life.).

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?

I own a 2002 Elantra with 75000 miles.
This just happened recently this winter. After a cold startup I hear a constant hissing noise (for lack of better word) coming from under the hood for about 5 minutes .
This is NOT the kind of sharp noise that you would hear from a loose power steering belt but it is definitely coming from that area (towards the passenger side close to power steering belt/alternator), though I could not pinpoint the exact location.
Everything seems to be working fine and after about 5 minutes it goes away. I am not missing any fluids and don't experience any other symptoms.

I started noticing some strange sounds coming from the engine compartment after shutting off the car ( a 2007 with 90K miles). It's different from the hum for several seconds that I often hear after switching off the car. This one is a squeaky rough sound like a small motor wearing out. I think it's from the driver side of the engine compartment. Is that where the inverter pump is? This car didn't have any record of needing the inverter pump changed for the recall as far as I could tell.

First off it's a 2008 Prius with 80K on it.
There is a new sound that has started coming from the front of the car in the engine compartment or even lower. It is a turning turbine like sound that is mostly obvious when driving at 60 mph, but my guess is that it is always there, but not as audible at lower speeds. The air and heater are both off and have no effect on this sound. The only thing that could have had anything to do with it is that a day or two before, the tires were low so I filled them to 40 psi. The other thing is that it clicked over to 80K the last week and the friendly red maintenance required light came on.

Recently, my 04 accent (97,000 miles on engine and auto trans) has started to develop a rattling or Clanking noise coming from the engine at low RPM's. I flushed the engine and changed the oil and oil filter, thinking it could be due to oil clogging the HLA, But this was a no go. The engine is still making the noise, and I think it is starting to get worse.
The noise only happens when the car is idling at low RPM's. As soon as I rev the engine past 1000-1500 RPM's, the noise stops. The noise is worse when idling in gear, either reverse or drive, however as soon as you accelerate past 1000-1500 RPM, the noise goes away, until you decelerate to low RPM again. I'll try to take a video of it and post a link to it on here tomorrow.
