I pulled the car in the driveway today and once I stopped and let it idle I noticed a moaning noise coming from the trans tunnel. I don't think it is the TOB, because I can also hear that slightly whining.

The noise goes away once you give it the slightest throttle input. It doesn't matter if the car is in gear or not, or if the clutch pedal is depressed. It always makes the noise.

It comes on intermitently, the RPM's will dip slightly and the noise/slight vibration will become much more pronounced.

You can't hear it from outside the car, and barely when you are under the hood. From what I have investigated so far it seems to be at the back of the engine/bellhousing area.

I am tearing my hair out with this car. I think I'm gonna have to sell it and buy an Evo.

Moaning?

It's not a whirring type noise?

Couldn't be exhaust?

This could very well be coming from one of your catalytic converters (my '91 has 4 of them) which are all up front. Sometimes they fall apart inside, or the exterior heat shields come loose, and can cause sounds like you are describing in that area of the car under those conditions.

Hit your cats with a rubber mallet and check the tightness of the heat shields.

(I am presuming that your car still has cats on it).

Good luck!
