efi idling problems

['88WhtNtchBck$]

any advise to fix my idle? My car was apart for awhile and now it idles high, i bought a new iacv and tps, but it still idles at like 1500 rpms, sometimes when i'm sitting at a light it comes back down but then it seems to be too low,

that sounds like a vaccum leak to me. make sure you have on all the proper gaskets when installing new parts. and check for work or cracked vaccum lines.

this should help you locate the lines for inspection.

if no lines are broke or cracked and you cant find a leak. see the surging idle checklist.

See "Surging Idle Checklist for help with all your idle/stall problems. The first two posts contain all the updates to the fixes. I continue to update it as more people post fixes or ask questions.
