Rough idle

Hi! I have an 05 Civic DX, recently replaced clutch and have developed a VERY rough idle. I have done a idle relearn procedure to no avail. Just wondering if someone had any thoughts or suggestions to offer. Thanks in advance.

Did you forget to plug something back in? Anything get bumped or damaged?

Re: Rough idle

Exedy clutch kits are recommended by many and either re-surface their stock flywheel, get another OEM Honda flywheel, or buy a high quality light flywheel.

Change your oil after if your flywheel is off balance.

If the car is not modified you will have to remove the whole air box assembly to get to it
