i recently took off my intake manifold(1st time) to get it polished + installed the greddy elbow and intercooler pipes. when i started my car it makes horrible noises and idles a 5 grand . i think i hooked up all the hoses right except the top left of the manifold where the hose from the bov connect, theres two nipples one for the bov and the other i cant find any hose to connect there and dont remeber if anything was there when i took it apart. also i didn't weld a nipple on the greddy elbow just put on a cap on the end that comes from the manifold . also i'm not sure if i put the throtle cable on correctly but dont know if this would rev the car to 5000. sorry for the long post - thanks

ok,i found the missing hose on top of the manifold - it was the boost gauge vacuum hose, now the car idles at 3000 rpms and still makes a horrible high pitch noise. would switched electrical connectors under the manifold do this ?? thanks

hmmm, make sure the throttle cable is not the cause, also there is a adjustment screw on the front of the throttle body, lossen that all the way and see if you still get this....

is the throttle cable supposed to have a some play to move both ways or is it supposed to be tight

no play, but not that tight

it could be your throttle position sensor. try this http://www.scuderiaciriani.com/rx7/TPS_adjustment.html

also make sure no part of the throttle mechanism is getting caught on something, like a hose or tie wrap.
