High rpms on idle
Hi iv got an 92 ssei and sudenly my idle got high .. i cant find any leaks and the engine is runing GREAT .. the idle is at 2500 rpms with no ac or gear but goes down to aprox 2000 rpm when il use the ac and gear in drive .. i doesnt display any SES and i dosent change anythig between cold or hot ,, could this might be the IAC that is stucked in open position ? right now im clueless .... anyone ?

EXACTLY MINE TOO HELP!!!
Checked all vacum connects and changed PCV and the lil grommets on it.
just changed intake manifold gaskets (was leaking coolant, puddled under plenum) and disasembled throttle body n cleaned everything to look like new.
Cleaned up the iac and tested with it unplugged, no change.
next is ECT, seems to run extra cool and i live in VEGAS (i did put an oversized truck radiator in it though it operates at like 140-160 F
TPS figure it could be screwy have to go get my ohm meter from the shop.
EGR think it might be hung open?
SPEEDOMETER also suddenly started cutting out intermittently and A/C cuts out when it does... Electrical?
on my way to buy a OBD I scanner will post code later....
