The car is a 95 eh2 with a B18c-R motor... Using a JDM P30 chipped ecu.

When i first start up the car it idles fine... no problem

after about 4 min of driving (warming up) the idle at a stop sign almost stalls out. Idles flutter between 200 and 500 rpms...

At operating temp, and for as long as im driving it fluctuates and flutters between 800-1100... Just goes up and down... up and down... Its not doing anything bad, and the rest of the car sounds like a champ... but it gts annoying when it sounds like im slowly revving the motor at a stop light...

Just thought id ask before i go start tearing stuff on the car... My inclination is first to take off the IM and clean it.. that and the IACV... if that doesnt work then a new IACV.. and if THAT doesnt work... i think maybe wiring or something electrical.... but i dont know what.

any of you have something similar?

 

Check the fast idle control valve by the TB, it was a bitch of a problem for me for like a week...There`s a screw type thermostat kinda deal there and if it comes loose, it will **** your idle up. Give it a lil once over
