Ford - F250 :: Buffering Or Low Whizzing Sound Coming From Smog Pump And High Idle
Apr 2, 2012
I have a 96 F250 w/a 351w, I can hear a buffering or low whizzing sound coming from the smog pump...(I know its from the pump cuz I took the hose off and could really hear it). In addition, I notice that even after the truck is warmed up I push in the clutch and the rpm's will stay at about 1100-1200 then slowly go back down to 900ish. But if I just let start it and it runs it will sit around 900 even after I rev it up.....? I am wondering, A. is the smog pump supposed to make that sound, ( I can hear it in the cab when driving and initially thought is was a small exhaust leak), and B. could there be any relation between the smog pump and the odd idle?

Had spilled little bit of gas in trunk, wiped it off and closed the trunk.
After opening the trunk next morning smell of gas in trunk and back seat of car
Left all car windows open 24 hours and trunk 6 hours,gas smell subsided 90%
While coming back from mall, while driving lowered both rear windows to maximum...as I was driving @ 50 MPH..Extremely annoying sound started coming from back windows area....it was unbearable annoying...so closed the windows and sound was gone.
Checked oil and it was full. What is this UFO sound with rear windows down.

trying to get my smog pump to run. I know its only supposed to run the first minute. took pump apart. impeller spun freely. connected to battery using jumpers. pump ran fine. changed relay that's located next to the 2 fuses next to the battery. the 30 amp fuse and the 10 amp fuse are good. there is no power getting to the pump. also have confirmed good ground. where do I look now ?

Baffled that my well-maintained 05 Corolla couldn't smog today. Smog checker said rpms were too high and it got kicked off the machine six times; said he had replaced his cable today. Manual transmission, 96,000 miles and had oil change last week; 93,000 major service included flush of something.

Noticed any excessive wind noise coming from driver's side window/door on their 3IS? Maybe because its pretty quiet but I'm noticing a slightly louder than normal "whizzing" noise (wind noise) coming from driver's side window/door..
Something the dealer can adjust / tighten up to eliminate this annoying noise?

1988 245 DL, 240,000 miles.
My idle is at around 1200. It should be 750. If I take off the flame trap the idle drops. The flame trap is not clogged and there is good vacuum pressure on the small hose. After replacing my cat the numbers went way down on the tail pipe emissions.
So my flame trap appears functional and not clogged but it causes high idle.

I have a 2010 f250 6.4 About two months ago the truck just quite on me. I am a farmer in south jersey and have a decent background in diesel motors. First thing that came to mind was fuel. I assumed I was having a fuel issue (clogged filters, failed pump, etc.) truck only had 45,000 miles on it so I took it to my local dealership for what I assumed would be a warranty job. I dealer service all my trucks while under warranty. Long story short I was told it was a fuel contamination issue which scared the walls of the hpfp throwing metal pieces into the injectors, fouling them.
I would need all new injectors, fuel rails etc. as well as new filter housings, fuel tank cleaning, etc. I had receipts for every drop of fuel put in the vehicle and fought all the way to through the dealership to Ford who sent out a rep and who denied the warranty work. Fortunately my insurance company covered the ordeal and all repairs were completed. I got the truck back and 2 weeks later the truck died on me again. I called the dealership back who supposedly warranted the repairs but there first words were there is no way it is their problem, they would look at it but I have to consent that if they find it is contamination again I am responsible for the repairs which we all know just to diagnose they have to remove the cab etc.
I of course lost my mind and told them this is there issue and there is no way in hell I am that unlucky that I received 2 bad tanks of fuel from 2 different high volume highway side fuel stations in the same 2 months. it is obvious they missed something or there is another issue that was not addressed. They claim there is no way they missed something. I am at a standstill.

Recently my 2011 F-250 Diesel with 21,000 miles seemed to start hard one morning. After starting the truck it ran well that day and started fine. The next morning it would not start. Had it taken to the dealer and they went to work. Started at the fuel filters and replaced low pressure fuel pump. Thought a piece of the defective pump had moved up fuel line. Removed high pressure pump and found signs of rust. All regular service intervals have been met. Didn't see this coming. No water in fuel light or other warning.

1996 Ranger 2.3 140 CID XLT 126,000 Miles. When coming to a stoplight or stopping the engine idle is low and causing engine to almost die. Engine has been stuck at high idle a couple of times. It started with the engine idle slowly coming down and now it its too low. I suspect the Idle air control valve.

Having an intermittent strange sound coming from the fuel pump from its normal whine at start up to a gurgling sound almost like you are blowing back through the fuel line back into the tank. Going on a 300 mile trip, should I hold off?
Btw: it's a 1996 Aerostar 3.0L

My truck has been doing this since I got it and I can't figure it out. It's a 2000 Ford Ranger XLT 2.5 5Spd. It runs fine if you don't rev it above 2500-3000 rpm. After you rev it that high coming down to idle it is stumbling real bad and sometimes stalls. I've been driving it like this since I got it, and it does fine other than this. It gets better the longer you drive it, but it still will do it if you rev it high enough.
Here are all the parts I personally have changed (previous owner said he did the plugs and wires and air filter, which it looks like he did but I'm about ready to change them myself):
-Fuel filter
-coil packs
-timing belt
-egr valve
-cleaned throttle body
-iacv
-tps
-thermostat

My 2003 T-Bird (52,000 miles, original owner and only driver) has a fan coming on occasionally (in front) while I am driving. No warning lights. It goes off when I shut off the engine but then I get a high pitched whining sound (in front) that shuts off after a few minutes. I took into the dealer and they checked out my radiator level (full) but found a pinhole leak in the radiator hose. "The engine is not overheating, not to worry, fan is electronic and is normal". I don't think its normal since this is the first time its doing this after 9 years. Could this be the same problem as Elaina is having: An evaporative emissions pump sticky valve or leak in this system?

I have recently noticed that there is a loud, high-pitched whistling sound coming from under my hood that has progressively gotten worse over the weeks. At first, it would only occur when I had my AC or heat on and would stop immediately once i turned the AC/heat off, and will also happen from time to time when I accelerate. Now, this noise is happening right when I start my car and takes a few seconds to stop.

Just bought my first Ford. Its a 2015 F250 Platinum. Im at 1400 miles and Im becoming concerned because when I start the truck for the first time in the day, no matter how long I let it sit and warm up I am noticing that on the first couple of miles of driving I hear a high revving sound as I accelerate and it seems to quick shift during those first few miles.
As I continue to drive the high rev sound just fades away and all engine sounds and shifting are as normal as can be and will remain that way until the truck has been sitting for an extended period of time and is cold. I thought it had something to do with tranny temp but this morning I let the tranny warm up to about 115 deg in neutral before taking off but still had the high rev for the first few miles. I have never owned a ford nor have I ever owned a heavy duty truck, hoping this is normal.

Recently blew the belt that runs the water pump, etc while on a vacation. Had to leave the car at a small mechanic in Winthrop, WA. He replaced the Water pump which had gone bad and the belt that shredded. The car ran beautifully for a week. Now there is this constant rattling sound coming from the water pump area. I attached a video with the sound. The sound will quicken as you accelerate. At cold start up it is usually not present then starts a couple of minutes in.

High pitched noise when car is running at idle and when not on the gas. Whenever I accelerate it goes away. Pitch/Loudness seems to be higher with RPM's. Could be coming from front of the car.
Checked so far:
I read some other posts about this and fully disconnected my aftermarket radio. I'm pretty sure it is not a ground loop as no power to HU shouldn't still create the whistle.
What I have:
I have an EIP aftermarket street exhaust. I checked the exhaust to see about the flapper, but I don't believe I have any of the items involved - maybe I'm wrong. After some more reading it sounds like a vacuum leak as it goes away upon acceleration. I need identifying what vacuum hoses are still in place/clamped off with having an aftermarket exhaust.
I do not have a CAI, just a K&N drop in.

My 11 cc lb 4x4 6.2 has a clunking/loose sound coming from the front end. It is prominent when going over small/medium bumps but not so much large bumps. I have had my local dealer and a couple local shops look at it and they all say everything checks out. It definitely seems like something is loose in the front suspension. I just put new Gabriel max control shocks on all four corners. I have no play in wheel bearings or ball joints. Tie rod ends also look fine.

My 88 2.3l 5 speed ranger was running fine then i went to start it up again and it wouldn't turn any of the cylinders or none of the belts move. i can hear the fuel pump turn on for about a second every time, there is weak fuel pressure at the rail. Why wouldn't the engine crank? the starter does not turn the belts and all i hear is a whizzing sound. it sounds as if the starter is spinning but not engaging.
I have had problems with the fuel pump relays but those are all taped up pretty good. I am leaning towards a clogged fuel filter or bad fuel pump. but even with a bad fuel pump or clogged filter wouldn't the engine try to crank even with low fuel pressure? I have a new battery in there. I checked all the fuses in the kick panel. I will check the inertia switch wires as the inertia switch has been disabled.

I have recently bought a 2007 ES350 that's runs fantastic considering I bought it with high miles from the Lexus dealer (149k). I live in warm climate area and I notice that even though it's not cold out in the mornings my car idles high (at about 2k) for only a few minutes 2-4 tops then starts to drop to normal as it warms up. It hurts me to hear it as I'm not use to this and I worry that it may cause damage to my engine due to oil not being circulated properly yet.
Most importantly, ONLY when cold, I hear a very light knocking sound, kinda like a bad lifter tick, but by the time I get to my daughters school which is about 5-6 miles away it goes away and sounds normal at that point. Had me very concerned as I just bought it less than a few weeks ago and I'm afraid something was wrong and dealer may been able to mask it at my point of purchase and now its starting to rear its ugly head.
This is my first Lexus ES350, not really sure if it's normal or not. I can tell you, when it warms up, I've jumped out of my car and have put me ear to the good and can't hear the tick. Should I be concerned? Is high idle with tick normal if it goes away when it warms up or is it a fair warning something is bad or about to go bad?
