Hello -

Awhile back I sold my 90 Sentra with the GA16i to my relatives and now it has issues. I idles way too high, about a constant 2K RPM's. The idle never fluctuates and never decreases when warm.

Any ideas on how to fix this? Does it have an idle air control valve somewhere? I could find only one vacuum line that was split and that didn't change anything. Could the ECU be stuck in "cold-start" mode?

Thanks for any help!

OK so I found the idle valve and solenoids, now I'm going to clean or replace them.
