When I slow down it sounds as if there is a hole in the intake manifold area 94 gt

Could be a leak...time to hunt it down. Grab a can of ester and see what you can find

Thx I pretty sure its the intake manifold its never been messed with tho but I guess cork only last so long

Looks like my vacume hoses shot

If you get a length of vacuum tube put one end in your ear and move the other around the engine bay... I was like "nothin... nothin... *whooosh* then it sucked the tube on and made my ear pop lol.
Also replace your cork gaskets on your Valve covers with some reusable fel-pro ones theyre a bit more but so much easier to deal with. might be time to freshen up the top end?
Also if you reset your base idle ( this is a new car right?) you should redo it now that theres no vac leak, maybe timing too.

Not new lol well over 200k been around the block she needs a lil love I just now got the means to do it tho but thx I'll take the advice on the new gaskets ima try to get a proformance intake manifold off a explorer or something let that puppy breathe
