Chevrolet - 1500 :: Loud Whining / Spinning Noise On Startup - High Idle
May 6, 2013
My question is what could cause a high idle?I have a 95 Chevy pickup 4x4 with a 5.7... Recently the lower radiator hose fell came off the radiator, dumping the liquids all over the street. The motor shut down, and every time we went to start it there would be a loud whining/spinning noise. We thought that the motor seized, so we pulled the plugs, turned the motor by the crank bolt.Turned out that the starter went bad, the spindle and bendex werent catching on the flywheel.
After examining the flywheel teeth, and gapping the plugs to the recommended manufacture gap, (they werent when we pulled them), we got a new starter installed. It started right up! But it ran at a high idle, around 1500-2000 RPM. I did not have a chance to really let it warm up (it was cold and raining). Now there is a gray flexhose that is running from the air filter housing down to the exhaust manifold. If i remember correctly, it was not seated very well when I took it off. Could it be causing too much of a vacuum?

Here is the noise that I am getting... Ignore the ticks and such, I'm talking about the LOUD whining noise at startup, and continuing at idle(although somewhat quieter)
[URL] .....
Some information : 2006 Camry 2.4L.
I have removed the belt to verify that the noise is not from any belt-driven components. Using an Engine Ear, it gets louder towards the exhaust manifold, but apart from starting to tear things down.

I have a 1995 4X4 Chevy Silverado. Well tonight the lower radiator hose came off, and all the coolant drained out while my wife was driving it around town. She noticed that the temp gauge spiked, and tried to get home. The truck stalled, was able to restart it for a moment, stalled again and now when we try to start it up there is a low spinning noise coming from the area around the starter. I think it might be the starter trying to engage the flywheel. My question is whether or not this could because the motor has seized, or is there another symptom that could potentially make this noise.

My '03 Jeep Grand Cherokee seems to be having an array of problems lately, I think they might be related. Almost 100,000 and its falling apart on me. When I start it up on cold mornings it has a loud whining noise. The check gauges light comes on and shows the oil temp as being cold. After leaving it idle for a bit, I will go to drive it and the heater will shut itself off. Later in the day after the first cold start, the loud whining and check gauges light don't happen again. But the heat shuts off every now and then. Is it all related?

I've got a noise that has me puzzled on my 1995 Chevy C1500 (2wd). I hear a mid to high pitched noise when I'm driving at between 45 and 55 mph (70-90 kph). It varies in pitch depending on the speed I'm going, starts at around 45 and goes away above 55, and also tends to go away if I lift off the gas. The sound occurs in any gear, but always at the same speeds. My leading suspect is the differential, but I haven't ruled out anything yet. I pulled the differential plug and the fluid isn't very dark.

Yesterday as soon as I started my car, I noticed a high pitched whining noise. As I drove, it seemed to stop, but as I slowed down and idled, it came back. After driving a couple miles, the battery light came on, so I turned off the AC, radio, and lights and it went off again, but as I sat at stop lights it would flicker on and off again.

Car wouldn't start, would just kind of do a high pitch whining. Bought new battery and still does it. It might crank right up or take up to 5-6 times. I'm a second owner and I believe it is the starter.

I have a 2008 Chevy Express Explorer conversion van with a high top. We purchased the van used in great condition in 2011. The sunroof leaks. It always has. I first called the Explorer company to ask what we could do. They said we needed to replace the seal. We ordered one from them and had it replaced. I was desperate to have it stop leaking that I had my husband put clear caulk to try and seal it up.
I am at the point of putting a tarp inside to keep my kids (4) car seats dry. The water has already damaged so much. Even the wood colored plastic now has a white haze (would like to know how to fix that if possible). Most of the water soaks in the ceiling around the sunroof and spreads out and down to the windows and in the upper cabinets. Is there anyway to fix this without having to spend more than we owe on it.

I have a 99 tahoe 4x4. It has 220000 miles. I had a wheel hum that got loud when I went faster and the pitch changed with speed. It doesn't seem to matter if I swerve left or right. I took it to a dealer and was told I needed bearings, both wheels. I bought the wheel hub assembly and changed them out. I figured it is just better to change the whole assembly. Well, I still have the hum and it seems to be getting worse. I don't know if the u-joint would do that or if it could be a shaft thing. I can not tell what needs to be fixed but can usually fix them when I know what it is. I don't know if there is a transfer case problem either? I know the shaft spins when I turn the wheel. I assume the lock for 4x4 would be in the transfer case? It seems to be getting worse and I don't want to do any damage. I don't get paid for another week and have to drive 50 miles a day.

Transmission comes out of gear and has a loud whirring sound when in reverse, but not every time. it has happened when driving at about 60 mph (twice) Sometimes it happens a couple times in a row sometimes it is ok for a couple weeks.

My 1995 chevy c1500 cuts out at idle or the moment the brakes are applied to shift into drive. I replaced the passenger wheel cylinder and bled the brakes and it ran fine for a few hours, then the idle problem stated again. I have check the map senor and a few other electronic component as my mechanic said the problem " might be electrical."

2004 1500 5.3 low oil pressure after using Lucas engine stop leak. No pressure at idle just below 40 when driving. Replace the sending unit and pressure improved for about a day. Just had a manual pressure gauge hooked up and it shows the same as cluster. No engine noise at all. I was informed that using Seafoam or another solvent could loosen up build up and cause damage. Trying to find out if using an engine flush machine may support. I am assuming that the cause of the low oil pressure is due to build up from using several qt of the stop leak over a four months. I am the only owner and I have always changed the oil according to schedule and have always used Valvoline synthetic.

I have a 97 Chevy K1500 truck that i have been having problem with starting. Sometimes it will start. When it does the idle is rough. When i put in in gear it almost acts like it will shut off. Then it comes back and it drives fine. If it shut it off it may or may not start. I had the distributor cap a rotor replaced. Then I replaced the spark plugs and wires. Still does not start. It seems like it is getting too much fuel. I pulled the fuel pump relay and the truck would start then die out. When i put the relay back in truck does not start. I am not sure what might be the next piece to look at. I was thinking the MAP sensor or the throttle position sensor. So far i have not had any codes come up.

I just bought a 2009 Chevy Silverado , have only had for a week and have noticed an irregular fluctuation in idle, also the transmission has lack of a better term jarred a few times and seems to downshift rough sometimes. The irregular idle seems to be worse when the ac is on, I can hear the compressor kick on and off alot. And just once I was driving and tried to accelerate and it didn't want to very much. Factory warranty is out and dealer didn't give option for extended warranty. They have agreed to look at it but aren't willing to do much other than clean injectors and throttle body.

After my truck sits overnight it starts immediately and goes to fast idle for a few seconds, then ithe idle starts dropping until it gets to approx. 400 RPM.If I drive off immediately it will correct itself in a short while, otherwise I need to baby the engine speed until it runs on its own - usually five minutes.I cleaned the MAF and performed a MAF tap test with no success.

I am having issues with my 2002 chevy cavalier.
The car occasionally surges forward while idle and revs up to 1500 rpm approximately occasionally when the air conditioner is on... if the brake is not applied I move forward.. the lurches are continuous every 3 seconds or so.
I am getting a code for an evap leak.. I have replaced the purge solenoid valve, gas cap, and checked all connections with no luck... slightly decreased gas mileage has occurred.
A little bit of a slick substance has been leaking from the car.. it has the consistency of water, but leaves a slight brown tinge on concrete.

Whenever I am driving 60 km/h or more a loud noise seems to come into play. The noise sounds like a really loose ball bearing spinning. Then sounds like a turbine slowing down when going 30 or under. The only issue is the noise does not go away until the truck shifts down into 1st gear. And when doing so the truck jerks enough for everyone in the vechile to feel it. This problem only seems to come when it's rainy or slushy outside and even then does not happen very often. I have had the truck to ford and another mech. Nobody can seem to pinpoint the problem. 2006 f150 5.4l ....

My vehicle has 113 k and when I start it cold there is a whining sound for about 20 seconds and then increases in pitch and then slowly winds down to a stop. Does not do it when motor is warm. What it might be?

I have a misfire in the 6 cylinder on my 98 Chevy c1500 5.7l 350 v8 2wd. I changed the spark plugs and wires, cap and rotor, and changed the spider injector i put the spider injector in from another engine I had. After doing all this the code still comes up. The truck runs fine and except it idles slight rough not bad at all and now it says I have a vacuum leak and while I'm driving you can feel the loss of power. I tried all the ways to do it like on YouTube. What is wrong with my truck?
