Should there be a gap between the throttle plate and t-body housing in the idling position or should there be no gap? I could see light shining through all around the throttle plate after cleaning. Thanks for any replies.

ahhh hmmmm? probably not.

i think it must be fuel injection. you might need to go get a new gasket! <IMG SRC="smilies/confused.gif" border="0">

Are you talking about the butterfly valve?

Well, if it closed all the way, how would the engine get air at an idle???? Does it work ok?

I thought the idle screw took care of that. <IMG SRC="smilies/smile.gif" border="0">

All around as in full circle, even right by the shaft? Any chance the throttle body was machined at some point in time and a stock size valve plate was put back in?

This is possible. However,
it is true, that the AIR plate,
when at rest, provides minimal
air intake - immediately around
the flow plate, intentionally.
Learned this the hard way, on a
nissan Z motor problem i was
having years ago.

Hi Shane. I believe it's all stock considering all the gunk I cleaned out of it but I'll ask the guy I bought it from though. Going to try the EFI conversion again using a later intake plenum and t-body.
