B18C idle problems
 

I have a 2nd gen JDM GSR in my 1st gen gsr shell...I'm still using the OBD1 wiring.

I had the computer chipped back in the day and everything was running fine. But now, when the engine is cold it revs at about 2500rpm. and when it is warm it revs at 1500...sometimes it drops down to 1000 and other times it fluctuates (anywhere from 1000 to 2000rpm)...

I've tried everything from retarding the dizzy, tuning my idle control screw but none of these things even affect the rpm. Even tho i kno it should.

I have no engine light on so i figure all my sensors still work properly.

I'm wondering if i should go find a stock gsr computer and try it or maybe I have a leaking vacuum line...

if you have any ideas lemme kno thanx....

first off is to change the pcv valve and then go from their you might have fast idle, and that maybe whats screwing it up. hope that helps
