Sentence structure leaves much to be desired. Please help. Anyway, your idle air control circuit is a reasonable guess. Another possibility is your EGR system. Some Hondas of your era had issues with the EGR passages getting filled with carbon and becoming blocked. This will cause driveability issues. I know it was very common on Accords, but not sure on the Civics. It’s been a while since I’ve had to deal with it. This is definitely something to check into.
