I have a stock 95 prelude with 190k miles. I havent been driving my car for at least 6 months. But now I just started the car the idle seems to be a bit rough. The rpm isnt stable and it keeps bouncing from 2k to 4k and so on. 6 months ago the problem wasnt there. You think the problem may be that i havent been driving it?

 

i checked every vac line there is. dont seem to be any vac lines. what is a iacv?

 

but the funny thing is that once the car warms up the rpm goes back to normal and the rpm becomes stable. the iacv seems to be fine?
