Civics have a MAP not a MAF. Your problem is most likely related to the ICAV or FITV. I see you've already asked about the ICAV but here's a nice little write up on idle trouble shooting http://www.ef-honda.com/ben/Badidle.php Also don't forget to check the online resources sticky https://www.honda-acura.net/forums/s...d.php?t=238067 there is a link to download the service manual in .pdf
