I recently have been hearing two different sounds from my 91 NA. The first sound is when I am in the 1500-2000 rpm range. When I feather or press the gas slightly, I get this whirl sound, like wooooooo. The other sound might be related to this, which is when I release the gas pedal, I hear like a thunk sound. What are these things? Should I be afraid? How do I fix them? Thanks guys.

 

anyone?

oh yea i meant strange up there not strangle

 

Be afraid, be very afraid.
...sorry, couldn't resist...

What area of the car are these sounds coming from?

 

The first sound is probably your stock e-fan... does it only do it when the engine is hot?

Where are the sounds coming from? Front of car? Middle of car? Rear of car?

 

i think the woooo sound is somewhere from the front and the thunk is from the bottom of the car. These are my best guesstimates.

ninja edit : this happens all the time when I drive, regardless of a cold start or normal temps.

 

The "thunk" could be a bad front diff mount...the "wooo" sound...woo-hoo?

 

Iis your Air Inlet hose from your air pump not connected?..that would make a "wierd sound".Also the Thunk..Bad Front Diff mount or U joints on Driveshaft,bad Transmission mount,broken Engine mount..the list goes on..Only By taking the time are you Really Gonna Know.Nobody can 100% Diagnose the car on the internet.so get a flashlight and Get Dirty!..My Car make an ARGHHH sound when I get into it.I found out it Was ME!..because I am Getting OLDER!(grunt and Fart!)

 

So would the air dump and it's muffler.

 

Also, if your alternator is dirty or going out they can have a tendency to howl a bit. The thunk is more than likely bad mounts of some kind (engine, diff, tranny, etc.).
