Hello
I have a 1992 s13 dohc I have this problem when the idle surges sometimes from like 1.3k to almost stalling sometimes it does. Drives fine but idles bad once warm. Would it be a Iacv I bought a new one but the plugs are different and I can’t seem to find one with the correct plugs. Also heard of people just blocking it off completely and it being fine. Please help me.

I would check the MAF, most common issues on s13, cleaning it doesn’t always fix it and rebuilt ones aren’t much better. If you do buy a MAF get a brand new one, I’ve had good luck with Blue Streak. Also the plug into the MAF can go bad as well, you can a new one from Wiring Specialties for around $20
