alright when i hit the thottle there is a weird noise and the exhaust note doesnt sound the same... i dont know how to describe it but it sounds like a go kart or a tapping.. it gets louder as i speed up and loud when im in a high gear...
when i lift the hood it sounds like its coming from near the thottle body

it kinda makes me mad because i just bought the car and theres no warranty:/

Is the sound coming from the engine itself? Or somewhere back behind?

It sounds to me like an exhaust leak, maybe a bad exhaust gasket.

+1 on the head gasket. Same thing happened to mine. My suggestion would be to get a mechanics stethoscope and find exactly where it's coming from. There's so many different noises going on under the hood it's hard to pick one out and know where it's coming from without a stethoscope

And your sure it's deffently coming from the throttle body kinda sounds like a donut gasket where the header meets the down pipe

You can stick you hand down where the header hits the down pipe when the motors cold of corse have some one rev it up you should be able to feel the exhaust coming out if that's what it is

I'm really thinking its an exhaust leak from somewhere.. check for exhaust leaks on rev like the guy above suggested and let us know.

Ac drain? Is it a hard line hitting the exhaust? If so, it could possibly be knocking on the exhaust at rev... seems kinda flimsy but its possible, may explain why you don't hear it when its idling

Those hard lines can be bent a little bit just be carefull and you can get it off there prolly not good for a line that gets super cold to touch somthing that hot could cause the line to burst I watched the clip a few more times I'm with blood I'm 90% sure it's an exhaust leak it's the manifold gasket or donut gasket

When you say a/c drain do you mean a line or the drip area...because the drip on a 99-04 causes a common manifold crack

Your passenger manifold is cracked/broken at the collector flange. Best bet is buy a pair of 94-98 manifolds from a junk yard.
Common issue with these cars.
