Stupid thing wouldn't work right .... Anyways . I did a kade to kade swap . Everything is hooked up right . It fired right up but idles from 300-2000 rpms . I'm thinkin maybe a vaccum leak but i don't know if that'd do it . My brake booster line was broke in half , but i patched it with a coupling I made from an ink pen and hose clamps . So any help would be much appreciated . BTW anyone know where I can adjust the idle ?

 

Idle adjust screw, look at the back of the intake manifold between/under the fourth and third runner. You'll see a little screw. In lowers idle, out raises it. Make sure you've fixed (not patched...that's ghetto) all vaccuum leaks first. Then unplug ur TPS, then reset your timing to 20BTC. Then adjust the idle so it's at around 700-750. Shut the car off, replug the TPS, and you're good to go.

 

Thanks . I figured it out . It was my intake piping

 

funny, i never had that problem until recently. not even on my old s13 ><

could the idle valve get clogged? already cleaned the aiv reeds and throttle body. so frusterating! guess ill double check the vacuum piping
