Accent LC (2000-05) :: 2004 - Constant Hissing Noise Coming From The Middle Of Engine Compartment

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.

Accent LC (2000-05) :: Tapping Noise On Left Side Of Motor When Running

I've got a 2001 Accent 1.5 liter 5 speed. Car has 105,500 miles. Whenever the car is running, it makes an irritating tapping noise somewhere on the left side of the motor. I've been told that it sounds like the timing belt, but the car runs perfectly, doesn't miss. The tapping used to go away 30 seconds to a minute after starting it, but now it's constantly there and slightly louder. The noise goes with the rpms. When the rpms are higher, the tapping is faster. I've also noticed some loss of power. I recently added some octane booster to the fuel but noticed no difference. My uncle told me it may be a main bearing starting to go out but the tapping does not have a metallic tone of any.

Accent LC (2000-05) :: Whining Noise In Second Gear If Accelerating At A Normal Pace

I have a 2005 accent with a 5 speed, it has about 80,000km on it.... mainly city driving. Lately, once the car is up to temp. as I pull away from a stop the car makes a loud noise and I really need to feather the clutch out. The noise continues after shifting into second gear ,but no other gears. Thus happens under normal acceleration. If I pull away extremely slow the noise isn't there. If I don't feather the clutch the car lurches like I'm just 'dumping' the clutch and driving like someone who is just learning to drive. Sometimes there is also a whining noise in second gear if I am accelerating at a normal pace. Where I should start looking? I am assuming it's the clutch due to the fact that it happens after everything warms up.

Ford 6.7L Power Stroke Diesel :: Slight Hissing Noise From Dash When Running A/C

I already have my suspicions, since my wife's GMC did the same exact thing a few months ago. I hear a slight hissing noise from my dash, when running my A/C. I took the system off AUTO, to see if it was caused by the automated venting system, but it kept doing it. I have noticed it the past week, and its becoming a little more pronounced. System still blows cold. It does seem that it takes the truck longer to get cool in the afternoons lately, but it might be due to it being so hot lately.

My wife's car did the same thing and blew cold air for a while....until the hissing became constant and very loud. Turned out, she had a leak from one of the hoses. Dealer replaced it, and find ever since. I'm thinking my system has likely developed a leak and has reduced system refrigerant pressure. Any other possibilities?

Neon :: 2000 - Hissing Noise / Clunk Coming After Every 4 Seconds

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.

Accent LC (2000-05) :: 2001 - Running Rough After Filling Up

A few weeks ago my car was running perfectly fine, i filled it up with fuel and then it started running a bit rough. Would drive ok but could feel it surging and if i backed off on the accelerator it would try stall.Also the fumes in the car were a lot stronger than usual. Got home and it stalled, started it up and was idling rough and blowing black smoke :/ no engine light has come on though. I did the typical thing and googled possibilities, the mojority said that it was the purge control valve so i replaced that with a new elantra one (part numbers were the same) and its still running rough We are now thinking it could be the oxygen sensor? Have checked vacuum lines and stuff for air leaks and cant find any. Unplugged the oxygen sensor while car was running and it made no difference at all.. If the oxygen sensor was working properly it would of affected how the car was running, right?

Accent LC (2000-05) :: Running Rough When Cold But Only When Accelerating

My 2000 Accent 1.3 has developed a problem recently: starts fine and revs freely and smoothly when parked. When I pull away it will get very rough like it's firing on only 2 cylinders or so, at certain points during the rev range rather than continuously. Very juddery.

After a minute or so, before the engine temp is even up to normal operating temp (according to the dial) it runs perfectly. When I start it up later the same day it's fine. It only happens the first time in a day that I use it. The more days I go without driving it the worse it is.

In the last couple of years I've changed spark plugs (always in good condition when I replace them), HT leads, coil pack, a lamda sensor (the first after the exhaust downpipe) and a fuel pump and filter.

Accent LC (2000-05) :: Intermittent Misfire / Running Rough

I have a 2000 LC that has a few symptoms - intermittent misfire/running rough at these times it has:

dark smoke
uses 3 times the fuel
loss of power (to normal)
will pick up revs slow without running rough and runs normal at high revs.
dies misses and then picks up revs slowly when accelerator is pushed fast to the floor from idle.

Hyundai mechanics checked computer and it coded change spark plug leads this did not fix the problem, and have no idea.

About 6 months ago the car was doing the intermittent thing when it died and liquid was heard splashing on the ground. I found the main petrol line connecting to the pump had come completely off. After replacing all problems ceased and the car ran perfect with full power etc.

I've checked the fuel lines none appear to be leaking etc.

Accent LC (2000-05) :: GL Throwing Itself Into 3rd Gear

I have a 2005 Accent GL with about 130k miles. When I start driving it, it seems fine for a little while, then it will throw itself into what I believe is 3rd gear and won't shift out of that for the remainder of the drive. The check engine light is also on now. I had my transmission flushed maybe 6 months prior to the first occurrence.

I took it to a transmission shop, they read the code, and then wanted $485 just to look at the transmission. I believe the code said "3rd gear incorrect ratio," but it could have been 4th gear too.

Is this a common issue? Is it likely a sensor or the transmission itself?

Accent LC (2000-05) :: Hard Starting / Will Not Stay Running When Engine Is Cold

My daughter has a 2000 accent , SOHC 12V, I think it's the 1.5L.. It will not stay running when the engine is cold...........after it warms up, or if it sits in the hot sun it's fine................it has 166K .

She said she took it to an auto parts store and had the engine code read, p1123 came up.....

Code P1123 : Long term fuel trim, at idle - mixture too rich..

What do you think this is caused by................ the inlet air temp sensor? I was told someone just replaced the air max flow sensor, that don't sound correct to me, but that's what they called it....probably the MAF sensor....

Accent LC (2000-05) :: Car Doesn't Want To Go In Reverse And 5th Gear

Just bought a 01 Accent hatch the other day. It's a 5 speed 4cyl. First gear through 4th have no problems. If I try to shift into 5th gear or reverse, the car doesn't want to go into them. The dealer I got the car from said that the problem is with a pin or something. I have never bought a Hyundai before this, I've had old 70s american cars. I was thinking it could be a shifter linkage but I figured I would ask you knowledgeable people about it first before I go and break something trying to fix something simple (hopefully simple.

Accent LC (2000-05) :: Sticky 1st Gear Occasionally

I have a 52 Reg Accent MVi and, occasionally when changing down into 1st gear, My gear stick sometimes doesn't want to go into place, or it will go into place but the car will still be in neutral.

Also, sometimes, when it feels like it hasn't quite gone in right, and i lift off the clutch, the car gets stuck somewhere in between gears and cant move, and i have to yank the gear stick (quite hard) back into neutral.
