aaaaaaaahhh ok, i got it.
i installed a 'freshly clean' throttle body wondering if it would be any
better (different TPS and microswitch). idle is still high (now actually
2100rpm), but now the transfer from 0% gas to 1% gas (and vise versa) is
super harsh.
i was thinking more about adjusting the throttle stop screw, but being that
the idle was once fine, i dont think it's the problem (???)
as far as the air aux valve, is there any way to check to make sure that
thing is working properly, other then disconnecting it when the car is hot
to make sure the door is shut? is it possible that could be the issue?
