You have a 70mm tb on a nearly stock motor? I think I know what the sources of the rough idle is then ... That's way too big.

 

idles fine.

its just that it leaks out the back.

 

You're causing yourself triple the work by having done the intake first instead of just keeping the intake put away until you got the heads and/or cam to go in with it. You're going to have to rip it all apart AGAIN. The cork or rubber front/rear lower gaskets are fine as long as you're using a stock intake. Otherwise, lay down a fat bead of RTV. Leave the TPS right where you left it. It's not supposed to be messed with unless it is out of range by a large margin. The screw you referred to as an idle screw is just a throttle stop and was not meant by Ford to adjust the idle. Be sure that it was backed all the way out before you set your TPS to the mid .90 range. I hope you're replacing factory bolts with ARP pieces as you go.

 

Ridgemoor, in palm harbor. by east lake high school for a reference for you.

we did the bolt sequence twice. got it all bolted down really good. but we used the supplied gaskets and didnt RTV the hell outta them. granted we didnt RTV the front and back gaskets, big mistake i can see now.

im going to get it tuned tomorrow or the next day, and let them deal with it. hell, im so tired and worn out from the fucking ordeal.

thanks for your help guys, especially Mars.

ill give you an update to how it feels when it gets back.

the TPS on the new throttle body was at 1.44, way too high.

and i wanted this on before may 2 anyways. the heads are a LONG time in coming as of now. might as well have this on till then.

 

no problem.

thanks for your help Mars
