Idle issues
I have a 93 auto, no mods. The idle has started to fluctuate after I have driven the car a while, 20- 30 min. No engine light, I have not checked for codes. The car runs great, no change in milage or anything.
Any ideas? Thanks for the help.

Very
likely the injectors are bad, run an ohm test (many articles on the subject if you do a search)

Could be a bunch of things.....you should check for codes first. Most autoparts stores will do this for free.
A basic tune up might do some good if she's been neglected. Things such as filters, cleaning the carbon off inside the throttle body (use throttle body cleaner) and idle air control pintle and check or you could be a plug problem (check gap and burn)....other things to consider:
Could be dirty sensors
Could be clogging cats
As mentioned above it could be an opti spark related issue
Good luck
