2000 Chevy Camaro 6 cyl Two Wheel Drive Automatic 64000 miles
There is a Resonance/whine noise that just started and it is most noticeable from in the car, it is not coming from engine compartment. It sounds like it is in the car under dash, under the floor shift console or from the middle to rear of the car.
The Car runs great, no stumble, no hesitation, starts all the time.
It happens a few minutes after I start it up and will sometimes will get louder/lower or go away for a few moments. Hot or cold makes no difference. When the car is in gear and I accelerate it goes away, when I come off the gas at a stop light or at idle in gear it is there. When I place the car in neutral and rev the motor it does NOT go away.
I thought it was the fuel pump but when I rev the motor at idle it is still there. It seems only when in gear under acceleration is when it goes away.
Is there something on the transmission, vacuum leak?
Fuel pump; but only disappears under acceleration?
Apparently, I did not remember asking questions before but I did so I will make a donation. Sorry
