the idle seems so go up and down. its pretty steady in drive, no so good in park, and it nearly stalls in nutruel. What do you think?
also, i was just wondering about somthing... right behind the font hood realease under the dash, there is a litlle cable coming out of a hose with a nob on the end. what the heck is that???

that little cable is your emergency hoo release that you pull should you other not work, its actually suppose to be held up by a small clip on the hood release handle bracket

ya its held up by a clip... ic
what about the idling, oxy sensor??

it might be an intake leek or a vacume leek.

Try pulling the IAC out and giving it a good cleaning. Carbon build up on the tip may be preventing it from working correctly.

sorry to steal your post, but where exactly is the iac? and what is that little box by the radiator cap. 85 gt v6. thanks

EGR!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

what is the IAC??

Hi IAC idle air control valve is roughly a stepper type motor or seleniod that the ECM
controls to provide more or less air as needed thru a passage biult into the throttle body, after a while carbon biuld can clog the conical pintle. it is on the oppsite side if the throttle cable, very easy to get out screws in abd has one oring seal thing just unplug carefully unscrew out out and flush out with throttle body cleaner, not carb cleaner!!!? to rset it unplug batt 30 sec and restart car go for short drive so computer can relearn or reset itself
this all siad use maanual for more precise procedure
good luck
