yea mine has the same problem but i just keep clearing the code every 400-800 or so miles then it comes back WTF it helps if you lower the idle really low (mines at around 650-700) otherwise cleaning the throttle body is a good idea like said above. o yea and i also got a ISC from a 1g in the junkyard (the beige plastic one) it was junk and i think it only works on 1g's correctly
 
aiight so i went to advanced n ordred an Air Idle Control Valve. the guy said it didnt matter for a 1G or a 2G and non turbo n turbo.. well it does.. this one, i guess ,was for a non turbo .. diff male n female clips... i was wonderin .. its been doin this for a while but i recently put in a XACT flywheel n new clutch.. could the lightend flywheel b causing this? im outa options.. wats its suposed to idle at n e ways. i herd that if u set the idle too high itll thro ## CEL.. if i set it to like 700 itll stall. and wat u use to clean out the TB??
