Ford F-150 (2004-2008) :: Slight Hissing Sound When Lightly Press The Accelerator And Then Stops
I have a 2004 F150 4.6L... There is a slight hissing sound under the dash on the drivers side when you lightly press the accelerator and then stops. No matter what speed you are going as soon as you apply the accelerator it hisses then stops. There is also the same hissing , only louder when the engine is cut off. It hisses for about 3 seconds. What could be causing this. It has been idling rough since the hissing started. The check engine light is on and showing P0420 and P0430 codes . The cats were replaced with resonators so I believe that is the reason for the codes.

Honda Accord Ex 2004. My AC stopped working today. After sitting at a light in the FL heat I heard a hissing sound of shooting air and the ac went warm. I tried a can of freon but the gauge read in the red and it wouldn't take a charge. It doesn't sound like the compressor is clicking on.

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.
Prius C :: Sound Like Some Metal Dropping On Concrete When Stepped On Brake While Making Turns
I heard some weird sounds, it sounded like some metal dropping on concrete, when I stepped on the brake while making turns. I know in the manual it says "Sounds may be heard due to regenerative braking when the brake pedal is depressed." in P.28, but was the sound normal?

So I was driving home from my girls house the other day, i stepped on the gas pretty decently, and instead of the normal "whoosh" from the intake, i hear the "whoosh" with an extra loud "whoosh" sound. Then when i came to a halt, the engine wanted to stall out and was sputtering incredibly bad. car seems to run fine @ 2k rpms+. Now it actually does crap out on me, so I am currently not even driving it.
I got fault codes p0300, 0301, 0303, 0304. random misfires in cyls 1,3,4 right? I checked my hoses and I don't seem to have a leak anywhere...
Ford - Aviator :: 2003 - Hissing Sound Near Rear Of Engine?
I have the '03 Lincoln Aviator 4.6 DOHC. It has a noticeable knock/ping/chatter and somewhat sluggish acceleration. I notice the PCV hose was collapsed and shredded. I replaced the hose and valve, didn't change idle or acceleration and I still hear the hissing noise in the same region. I unplugged the EGR valve and started the truck, the idle was the same as before I unplugged the valve. could a bad EGR valve give a vacuum leak that is hard to detect? I tried testing for leaks by squirting starter fluid near the suspect areas, and I couldn't detect anything.
could a bad PCV valve be caused by a bad EGR valve and/or vise versa?
Buick - Lesabre :: 2004 - Hesitation When Stepped On The Gas
Driving my car over the week-end and experienced a lot of hesitation when I stepped on the gas. The car seemed to delay in kicking in to the next gear.I stopped and checked my transmission oil and realized I didn't have much transmission fluid, practically none. So, I added a quart. My question is what should I do now. I know it probably doesn't have enough but I don't know how much to put in. Or should I just have it changed?

My truck is running fine but it sounds like there is an air leak on the drivers side of the truck. When it first happened I was passing a car and it sounded like a vacuum hose come loose. It made a loud hissing sound. Now I have come to the conclusion it must be associated with the turbo. I don't hear the hiss unless I get into the truck and the turbo starts making boost. The more boost is made the louder the hissing sound is.

My Explorer overheated yesterday. Found a very loud hissing sound coming out from under the hood. Let it cool off filled it with antifreeze, started it up, started hissing again. Found the thermostat had broken. Replaced the thermostat. Filled it up again. After replacing the thermostat I found out the hissing sound was coming from the plastic thermostat housing. Replaced the housing. Again I refilled it with antifreeze.
Started to let it warm up and noticed liquid dripping out of the exhaust pipe. Checked it out. Had a green color to it. Then I noticed the coolant resivor was full up to the cap. I did not fill it up past the full line on the side of the resistor. Tried removing the cap.
Found out it had a ton of pressure under it. Bled off the pressure. Refilled it again. Did not put the cap back on. Tried starting it. Instantaneous geyser. Runs like it is missing on 1cylinder. No oil in the coolant that I can see. No coolant in the oil. Could this problem be caused by a blown head gasket of a crack in 1 of the heads or in the block?
Ford Super Duty (1999-2016) :: Hissing Sound From AC That Lasts For A Couple Of Seconds Then Goes Away
I used the a/c for the first time this year on my 2013 F250 and heard some noises I don't remember hearing before. When the a/c(or defrost) is on every 12 sec or so I hear a hissing sound that lasts for a couple of seconds then goes away. Is this the compressor cycling and if so is it normal to hear it inside the cab?
I know it has to do with the a/c because if I shut it off as the hissing sound is being made the sound will instantly stop. Other than the noise the a/c works fine and blows cold air. Also, if it matters I have the standard control panel, not climate control.

Started the car the other day and a loud whining noise followed by the car "jumping" when I stepped on the gas. It would go/stop for a second, then shut down. Mechanic who is not a Prius expert said it was the tranny. He could put in a used one (77k miles). Car has 250k miles on it. Is it worth it? Or should I just part it out. I'm worried about things like the battery going next.
View 8 RepliesFord Excursion :: 2004 - Thud Sound When Back Out Of Driveway
I did some searching on brake and suspension related issues to no avail. When I let our excursion sit overnight, and get in it to leave in the morning...drop it in reverse and let off the brakes, I get a 'thud' noise in the rear of the vehicle.
It sounds like a brake pad sticking and immediately freeing itself when the vehicle is in motion. We don't set the parking break. The brake pads and rotors are new, calipers and pins moved freely, parking brake shoes seemed to be in great shape.
The only thing I noticed was a small leak from the rear axle seal which could possibly be saturating the ebrake shoes and causing them to swell and stick overnight. The only other thing I can think of is maybe suspension related.
I have noticed it when pulling forward into and out of a prolonged parking spot so I don't think it is driveline related. It also doesn't occur any other time except for after sitting for several hours.
It sounds like the spare tire is loose and rocks forward slightly and hits the back of the seat. I checked that also. Very faint thud..

Ford 6.7L Power Stroke Diesel :: Hissing Sound Coming From Engine Mounted Fuel Filter
I changed my fuel filters a couple weeks ago. When I opened the hood the other day i noticed a kinda hissing or sucking sound coming from the engine mounted fuel filter. I've watched epics video a couple time and think his made the same sound but not sure. I am just paranoid with all the hpfp problems. It runs fine and had no long starts or hesitation at all. Lemme know if you all have the same thing. I just can't remember if it sounded like that before. I have done the air purge properly and several times since changing the filters. I notice the sound while doing the air purge procedure with engine off and key on.
