alright so I took a long drive to a casino tonight (I lost) lol .but just got in town and turned a corner and a rattling noise coming from under the car.only when I give it gas .when I driving and throw it in neutral it goes away its pretty annoying .when car is in neutral it does it when I give it gas .right under the engine.wondering if its a heat shield .I cant check till morning .

 

Given the weather, and the age of our cars, it could be just about anything. If it's happening regardless of gear, it's probably one of your heat shields. A blown or almost blown motor or torque mount could also be exacerbating the problem.

 

tthe car seems to drive like its perfect .just rattleing noise .kinda right under clutch

 

a blown or almost blown motor mount or torque mount would still let the car "seem to drive like it's perfect". Just tossing it out there as something else for you to check.

 

how would I check for these things?

 

Have a friend rev the engine in neutral while you look at it and check for excessive lateral movement.

 

I did that earlier and tried to look for anything and nothing .when I was driving at a low rpm it didn't make the noise till I gave it more power .

 

If you still have stock cat, check heat shield w/o engine on by shaking it or lightly tapping it w/hammer handle not head. Little pebbles love to get trapped in there.
Hopefully its not a spring/bushing in the clutch that's rattling loose.
Another way to check mounts is w/eng off, car in n, e brake on, eng cold. Grab on to front and back of valve cover and push/pull pretty hard. Engine should not move front to back any more than 1/4 inch. If so your rear mount is shot. Side to side shouldn't move @ all.
