Might be a dirty oxygen sensor. Is this 323 an around town, short runs type of use vehicle? If so take it for a hard run on a country road. Dale P......... aka Diddly

!999 Mazda 323 with erratic, slowish idling. Drives quite normal everywhere else. Sorry about off topic, figured there would not be too much of a difference John
The first thing I would do is get some xylene carburettor/fuel injection cleaner and flush out the throttle body and idle air valve. You may need to adjust base idle afterwards, since this will remove 9 years of gunk.
Don't clean off the black ring around the edge of the throttle butterfly itself, since some of this is factory sealant.
I tried some possibilities ( etc.) but with no success. ____________________________________________________________________________________ I want to sell my 'beauty'
Rather common and usually pretty easy to fix. Pick up a spray can of throttle cleaner at parts store and follow the directions on the can. A small amount of dirty or oily residue/gunk in the throttle body really affects your idle. Also consider having your fuel injectors cleaned, but try the throttle body cleaning first. Both operations will raise your gas mileage.
