only cold , idle is unstable?
Hot what does it do?
what timing, ignition or cam?
are you tuned up? plugs, filters?
could be many things, including stuck IAC/ISC (idle control valve) or EGR sticking. they can be cleaned and it is common to do so.
ISC is in diff. location on 1.6L and 1.8L this year.
on 1.6 , the ISC bolts to Intake manifold and has 1 air tube and 2 water tubes.
It controls the idle under cold start conditons.
Dont have fSM this year but there may by some other hot idler controller under TB or ? the ECU controls directly.
