There is a baby under the hood.
bad transfer case
your Imagination.... :)
An air conditioner should not smell like smoke when turned on (or when turned off). I would have to suspect that the electrical insulation is burning.
If it's a type of clunking noise, check your gearbox. If it's some kind of rattling, check your hubcaps.
You should really go to the doctor it could be neumona I would go get that checked out
Check to heat-shield at the catalytic converter because something is loose
I'd like to know too! Mine does the same thing - it makes a rattling noise upon startup that goes away after 30 seconds or so and isn't present while driving or idling.
it may be your tire alignment. your tires may need to be re-aligned. a couple of months ago my car started making a rattling noise when we would go about 70 mph on the highway. we found out are tires needed to be aligned again.
I had the same question until my wife noticed the tag rattling as I took off, I put 2 rubber pads behind it and the noise stopped! I had the same question until my wife noticed the tag rattling as I took off, I put 2 rubber pads behind it and the noise stopped!
It's probably your shock mounts, I had the same problem. The noise went away after I replaced the shock mounts.
Possibly bad throwout bearing
Well without further analysis or information, a short answer would be that your engine is BROKEN.
With just that to go on I would say that your clutch release bearing is going bad especially if the noise quits when you put pressure on the clutch
bad wheel bearing may cause it
check a/c compressor and belt.
It could just be the heat shield on the under side of the catalytic converter.
Check pLugs and wires and the vibration my be from brake pads or warped rotors
An AC runs at a quiet would be 40 dB.
It sounds like your ignition timing timing is too far advanced. It will need resetting.
Check wheel bearings - quickly! Very dangerous left unrepaired!
You could be very low on oil, check your oil and add to the full line.
I own 2 Jeep Grand Cherokees. I had the same issue with one of mine and it turned out to be a bad catalytic converter which was making that nasty banging noise. It would mostly make the noise when sitting in one spot idling the engine. You will have to get that replaced before you can pass any future emissions tests. Good Luck It might also be your water pump going out. Where does the sound come from? Front of engine or below? If it is front - check water pump. Remove fan belt and see if water pump will wiggle up and down. If below, does the engine emit a 'stinky; smell. Sometime, the c-converter can emit a methane like odor.
Try to locate the rattling noise. I would especially check the catalytic converters if the noise sounds like it is coming from underneath the vehicle. Usually throughout some time the honeycomb material inside them will break up from 'heat stress' and will rattle around there. In some cases it can get lodged int he pipe between the converter and the muffler blocking some of the path of the exhaust causing some major performance issues.
The most likely cause is an inoperative radiator fan.
