Ok guys here the issue. my 1994 civic EX w/D16Z6-sohc vtec is running alot better after cleaning the IAC valve out. however now it runs ok and all it just has a searching idle. as soon as you come to a stop the idle will fluctuate from 550-1500. after about a minute it will come back to normal idle. but cant figure it out.

Maybe its the PCM? IAT?

Thanks

also car has new plugs and wires-no vaccum leaks I see

How andwhich way do I need to adjust the throttle cable?

Also how do I remove the lower idle valve?

any ideas where to start looking for vaccum leak?

Could the FITV being bad create a vaccum leak? thought I read that on here somewhere when searching for my answer

yeah just take those 3 or 4 gbolts out of it, then take it apart, and you will see a thing in there that fits a wide flat head, tighten it down.
