weird throttle noise

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

What are the 99-04 manifolds made of? Cast iron?

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.

Wow were they exhaust shops? My locals will weld them. Tell them its not a header but a cast manifold. Then if they still say no laugh at them for not having enough skill to run a bead. You could use blue magic exhaust metal putty....it seems to do some good size cracks at least from what ive seen

One guy said he couldnt do it because it was cast and one said it would only last 2 weeks so he'd rather replace it.. i think they are trying to get me to spend more

++^^ exactly, they are steering you toward already permanent, lasting solution.. As a business owner they don't wanna don something half assed like weld up a manifold vs replacing it for just a little more money and know they made a repair that's not coming back to bite or haunt them.

Then your best option is to use what slowsix suggested or JB Welb or some other band aid until you can get some headers. You can probably get the ones lowFlyn suggested on eBay pretty damn cheap.

Well you can feel an exhaust leak, if its a lifter you will hear a tapping sound, grab a screw driver, put the steal side on the valve cover, and put the plastic side right up to your ear. Then just listen and see if you hear wear noises inside, you could always go to the other valve cover and see if it sounds the same or different.
You can do this trick on anything really and hear inside better.

You don't need new headers. Temporary solution is go to a scrapyard and pul one out of an old mustang. While you're at it find a tube to move the ac drip away from the manifold

It's the weld where the collector meets the log on your manifold. I'll put money on it.
