So I noticed a few months back the car[87 GN] would sometimes have hi idle,sometimes turning the car off and on again seemed to reset it.If the car was started cold and driven and not shut off it seemed fine.but on restart it may have had hi idle.So my Gn guru friend says ahh its a bad chip-so i threw in my TT race chip,problem gone[short drive],so I installed my old Red Armstrong street chip[again short drive]Thinking it was a bad Tt chip,I slept good.next morning[today]hi idle from the get go!And now worse than before!I tried all my other chips-still hi idle.About 1000 rpm warmed up in gear!vacum gauge reads 15[in gear]19 idle.Dont think its a vacum leak cause why would it go away before when i restarted it?I reset the tps to .44[was at 50].IAC seems hi?[60ish]
Could this be something with my IAC?Id like to "reset" if I knew how,or do I just change it?Any Jobber store unit ok?Am i barking up the wrong tree here?I got the old OTC 4000 plugged in to answer any questions where my numbers are at.
Just had car running and warmed up IAC at 40ish in park-toss it into gear and it shoots up to 73?02 at 43.
K so engine off key on-tps at 42 and IAC at 140.
I went and bought a new AC Delco IAC,installed it-car runs the exact same!!
same numbers
Thanks!Rich
