My 86T has been garaged for 3 months already. Prior to that it was not idling or if did idle will idle at 600 then 500 then 300 then Die. Been just taking my time to figure out and replace or tighten things that have made it much bettter then the serious flu it just had. I discovered the plastic tube that goes from AFM to Turbo inlet was loose. Ok so after tighting that to tight that the rusted stock bolt broke off,I had to take the whole plastic elbow off and put in another bolt after took old one out. No problem, just a little annoying getting it back on. Oh also cleaned the plastic tube inside with carb cleaner and water before putting it back. Then I found the annoying Vac leak I had for sometime, but ignored it cause did not know until now it was from a tube under the TB I never saw. Saw I put tube back on. Vac leak is no more music in my ears. Then I replaced the fuel filter, When I took old one out,I try blowing air into it with my mouth, and was able to do so,but not with ease. The new filter with no gas inside was easy to blow air into. Then again I do not want to take it off to find out if it still lets air in as easy. But Im sure it was clogged. Now the car idles for sometime, about 3 min or so at around 400 rpm then dies. So All I have to do is up the idle. I tried turning the screw but it will not move. Pain in the ass? I know I moved it before. So maybe I will buy a new Idle control valve from nissan and well then everything should be ok, once i get that idle up a bit.
