Lumina :: Hissing From Driver Side - How To Find Vacuum Leak
How can I find a vacuum leak? I hear hissing from driver side. I used 2 cans of starter spray and on throttle cleaner. No change in rpm.
I'm on the of my Latin. If I pull the throttle short and raise the rpm I hear a loud air soak. But I can't locate it. Can be the egr, lower intake upper intake or fuel interceptor. I begin to hate the car.
Lumina :: 1995 Chevy - Excessive Fuel Tank Pressure / Slight Hissing Periodically
1995 Chevy Lumina 3.1L Sedan with ~182K mi
Over the past 6 months, I have noticed fuel odor just about any time I turn off the vehicle, and I am also experiencing progressively higher levels of fuel tank pressure each time I remove the fuel cap. The fuel tank pressure seems to be greater the lower the level of fuel in the tank whenever I remove the cap. 6 months ago (~Sept) it was only a slight "hissing" periodically when removing the cap to fuel up, but now it occurs at every fill up and seems to have enough pressure to push the cap entirely off had I not been careful to slowly loosen the cap to relieve the pressure.
The entire fuel pump and sending unit assembly in addition to the tank and filter were all replaced about 4 years ago in May 2010 or about 28K mi ago. The issue has just come up progressively over the last 6 months.
Today, I inspected the evap. emission components and lines from the tank to the canister to the purge solenoid mounted on the rear of the engine. All lines are connected and seem to be in operable condition. The line from the canister to the purge valve mounted on the engine is completely free with no obstructions. I blew out the line with compressed air and absolutely no exiting particulates were observed. The lines on the bottom of the canister did not show any signs of wet fuel and there were no carbon particles present in the lines from what I could tell from disconnecting and inspecting. The vapor line from the tank to the carbon canister is not kinked or pinched in any manner.
I believe there is a fuel vapor check valve that resides inside the tank connected to the fuel pump assembly/sending unit. This was all replaced as a single unit as mentioned above. I am thinking this check valve may not be functioning properly and not allowing the vapor to escape into the carbon canister. I tried to apply slight pressure and vacuum on the vapor line connected to the check valve on the tank but no air was able to move in or out even with the gas cap off. However, I do have a full tank of gas right now, so I imagine the check valve will be closed.
The check engine light is not on but since this is an OBDI vehicle I am not sure there are any evap. emission codes anyway.
How can I test the gas tank vapor check valve? How can I test the vapor purge solenoid located on the rear of the engine? What malfunctioning component could be causing the excessive fuel tank pressure.
Radio - Chevrolet - Noises - Lumina :: No Sound At Any Volume Level
I have a '99 Lumina and a few weeks ago lost all sound from the stock radio. It powers up and everything else appears to be working normally, but I get no sound at any volume level. All the fuses seem fine, as does the antenna connection. I also tried grounding the radio to the chassis, but with no luck. This weekend I went to the local scrap yard and pulled three stock radios from three similar Luminas ('96, '98 and '99) with no real success. One radio produced sound, but constantly went from low to ear-blastingly loud; the one from the '99 behaved just like my current radio; the final one played normally for about one second and then faded to an almost imperceptible level. I checked online and all three cars show the same radio wiring harness, though I can't rule out the possibility GM changed the wiring just enough between each model year to cause those issues. I don't mind putting in a new radio if it fixes the problem, but don't want to spend the money if my trouble is actually in the car itself.
View 4 RepliesSubaru - Outback :: Weird Fizzing And Hissing Noises
Today, just after starting my car, as I was driving I heard a noise that sounded like paper shuffling in the back seat. I pulled into a parking spot and got out and checked the back seat and didn't see anything odd there.
I continued driving and then (I think while braking, not sure) I heard a weird hissing/gurgling noise almost like someone letting fizz out of a soda bottle. It sounded like it was right over my head, behind me. Then I heard what sounded like something falling from the back seat onto the floor. (a light thud but it sounded close to me, inside the car) Then all noises stopped and everything was normal for the rest of the 15 minute drive home.
I seriously doubt it was the brakes though I was told my brakes will need replacing soon.
I have definitely heard noises behind me that turned out to be in front of me and vice versa so I suppose it could have been coming from the front. When I got home I cleaned out the back and looked under the hood and seats to see if there were any animals in there. Didn't see or hear anything. I know brakes can squeal, grind and vibrate but can they hiss?
Stalling - Gasoline - Pump - Chevrolet - Noises - Lumina :: 1997 - Loud Humming Noise?
I bought the car( like six months ago) there has always been a loud humming noise from the fuel pump ( I'm pretty sure it is the fuel pump anyways) not the normal whirring noise the fuel pump makes but a hum you can hear about ten feet away. Had no issues till just lately when the afternoons are well into a hundred degrees. That is when my car starts giving me issues. After one of these hot days on my ride home from work, I had just come off the highway and stopped at a stop light when I felt the engine bogging out, the engine stalled and I had to push it to the side of the road.
Its worth mentioning that this humming noise is much louder in the heat than the cool morning then when I turned the key to hear the fuel pump(auto fuel inject) it was louder than it has ever been, and would keep stalling on the way home, I had at the most a quarter tank of gas (gas boy is busted/stuck I think) the fuel pump is bad? Could it be the sock? I thought I read somewhere that my girl pump uses gas to cool down, and that having the tank any less than a quarter could lead to the fuel pump overheating????
Ford Ranger / B-Series :: Hissing Noises And Idle Fluctuate Between 2500 And 3000 RPMs
Truck: Ranger
Year: 1990
Engine: 2.3 Lima
Trans: 5 Speed Manual
Miles: 83,445
Recently Replaced:Oil Pressure Switch
Oil Pan Gasket
Crank Position Sensor
Spark Plugs
Plug Wireset
Ignition Control Module
Driver Side Coilpack
After I got done with all of this crap on my Ranger, I noticed that it was driving great! But...today I was on my way to school and BAM! My engine idle started hitting (presumably because I do not have a tachometer) about 3000RPM and lowering down to about 2500RPM and from there, every time I am not in gear it decided to fluctuate between 2500RPM and 3000RPM. Crazy style too.
Now, I got to school, and getting closer to it at a stop light the truck basically died. It was almost at 100'ish RPM. I gave it gas, and BAM. I hear a continuous hissing noise from under my hood. Haven't diagnosed it fully yet because I just got home and its 12AM.
Now, every time I stop at a light or in traffic or whatever it may be, I have to give it gas every other second, like a small push on the pedal, to make sure the truck doesn't die. Also, every time I am out of gear and my RPM's are at an 'idle' state, I get continuous hissing from somewhere, I get no power loss or anything, just really weird idle RPM's and hissing when my foot is not on the gas basically. It is strange. I think It is some sort of Vacuum leak but I am not sure.
To get a better picture of the 'hissing' noise, it is the same hissing as you would hear when letting the air out of a tire. That is the best way I could describe it.
Camry :: Car Started To Shudder When Applying Brakes
I have a 2003 Camry LE 4cly. Approx 150k miles. Car has been a good Camry. About 6 months ago it started to shudder when applying brakes. At first I thought rotors, but it seemed speed dependent. When over 40 it happens more often and more strongly. After the car gets below 10 to 20 the shudder ceases. Front pads are in reasonable shape. Rotating tires does not affect the shudder. Has never effected handling of vehicle. Brakes work without fail, just shudder in front end and steering wheel. I tried flushing the system, had not done that previously. Fluid was yellow, but not black. After the flush, the system seemed to shudder less, but still have the intermittent shudder. There are no error code for ABS, and the light is not on and does not come on.
View 5 RepliesGolf VI R :: Slight Vibration When Applying The Brakes
So having done a single track day, I feel like my rotors must have warped, as there is now a slight vibration when applying the brakes. This is very surprising as I don't do anything out of the ordinary, and tried to use brakes intelligently, including a proper cool down lap and so on. Is this normal? What are my options for making life better? Is there some set of rotors I should get that wouldn't be prone to warping like this? Is it a question of pads?
View 18 RepliesPassat (B6) :: Suspension Noise When Reversing And Applying Brakes
I had been hearing bang noise from my front suspension at certain times like when reversing car and applying brakes. It was happening since I bought my car and every time I have complained about it to local VW service guys, I was told by them that they cannot replicate the noise so there is nothing wrong. I even told them to have a look at front suspension bushings but again they said everything is fine.
Last week I went for 45.000KM Service and I complained about the same issue again and luckily this time service advisor heard the noise himself. Next day, they called me to inform that my front lower arm bushings needs to be replaced, front brake pads and discs, and front wheel bearings as well. In my response I told them that bushings were bad for long time and no one figured it out earlier and due to this my front brake discs had abnormal wear along with the wheel bearings.
I am still trying to relate that it is technically possible for brake discs at least to wear off earlier if the suspension bushings are bad as when you apply brakes, the brake discs are stressed heavily as the bushing are not absorbing any stress.
I would like to have thoughts on this matter. Just let me know if my understanding is correct or it does not makes any sense and technically would not be proved.
Just to let you know that it is 3.2 4motion model. My driving is average within 120 KM speed and never hit any potholes etc. Plus my brake pads indicator never went on.
Accent RB (2012+) :: Crunch Sound When Applying Brakes
I haven't noticed it before but applying the brakes after driving thru snow I get an awful crunch sound. I have stopped the car a few times to look and it appears the wheel wells are clogged with slush but I don't know if that's whats causing it. After the crunching sound if I'm driving on a clear road there is no noise if I brake. Its much worse than say the crunch you get if the brakes are wet. Whats up with this?

View 11 RepliesTiguan :: 2011 - While Applying The Brakes The RPMs Will Go Up While Slowing Down
Just got the Tiguan SE- love it! We have had it for about 3 weeks. I noticed sometimes while applying the brakes, the RPM's will go up as I am slowing down. I know the car has to move between gears when slowing down or speeding up, but it almost as if it gets "stuck" in a gear when the car is slowing down. Any thoughts, input? We don't drive fast, we apply the brakes and gas slowly to ease the car in. This just seems odd as my past car (2005 Maza 3) did not do this. I am new the VW family so maybe I am just not used this.
View 6 RepliesPassat (B7) :: Pedal Feels Almost Loose When Applying The Brakes
2014 Passat... I've got a little over 2,000 miles on mine now and I really do like the car. However, one thing that is really bothersome to me is----the brakes.
I'm not sure if it is specific to my car or to the passat in general. Here's the issue:
When applying the brakes, the pedal feels almost loose, as though the is no pressure on it, but once you push the pedal down far enough the brakes come on heavy, hard and fast. It's like turning on a light switch.
I am wondering if this is an adjustment that I can have done at the dealer to put more feel into the brakes or if this is just something that we all have to live with, of if maybe there could be something wrong with the brakes on my car.
Prius (Gen 3) :: 2013 - Groaning Sounds Occasionally When Applying Brakes
I have noticed brake groaning sounds ocassionally when applying the brakes. When this happens the pedal seems spongy takes longer to stop. After the car is turned off in the garage I have heard the same kinds of sound coming from the car. It almost sounds like the car in sequencing through checks after the system has been turned off.

02-F150-4.2L-102k. Truck was rolling down the road at approx. 35 to 40 mph. A speed bump/table appeared out of nowhere and was hit before beeing seen. Immediately since this event, the truck pulls to the left while applying the brakes. It pulls very hard and is fine while rolling down the road. Is there some damaged steering component or did one of the calipers go out from the jolt?
View 4 RepliesAccent MC (2006-11) :: Rear Drums Clicking When Applying Brakes?
I am having a issue with my 07 accent. Had front rotors and pads replaced because they needed to be. Clicking continued. Had drums and shoes replaced last month. Clicking went away for a few weeks. Recently started back up just the other day. The clicking is only when applying the brake and it sounds like it is coming from the right rear drum. It doesn't interfere with stopping, but it s so annoying and brakes shouldn't make that kind of noise anyway.

I checked again with same results, is been posible that my brake discs could be damaged or something is wrong with the brake system? I didn't have any light of malfunction. What is the normal life of brakes discs and pads in a santa fe with normal use?
View 13 RepliesSonata NF (2006-10) :: Ticking Sound When Slowing Down (applying Brakes) At 35 / 30 Mph
I am getting a ticking sound when i am slowing down (applying my brakes) at say 35/30mph. The sound stops when I stop. This problem starts after my car warms up; doesn't do it when I first start up.
I've taken the car to 2 Hyundai dealerships and a certified mechanic and the problem continues. I first noticed this about a month ago.
So far no one seems to be able to find the problem. The mechanic did try by replacing the front brake pads. He said something about a "shims piece " and thought if we replace the front pads that would take care of the problem. The rear brakes or ok.
I'm still having the problem and I wonder if it's the rear brakes after all. I don't know what I can try now. Someone suggested going to Brake Check. I have about 1000 miles left on the original warranty.
