Nissan Repair: 1986 nissan micra idle

Question
my girlfriends 1986 Nissan micra wont idle

Answer
Hi Andy -

Is the check engine light on?

Does it perform OK when you rev it up or drive?

Does it start OK, but just won't idle?

Does it matter if the engine is cold or warmed up?

The more info you can give me the better.

LMK
aloha
