Alright my car's been Idling rough for a while now. I've read to check and clean your throttle body, so I went to AutoZone and bought some throttle body cleaner. Last week while looking under my hood I noticed some hoses looking pretty checked nd weathered so I went online and bought a nice high quality (not cheapo $20 Ebay kit) colored hose kit for my car. Well never got around to cleaning my throotle body yet, but today at lunch I had a little extra time so I started changing a couple hoses from the bypass valve to the supercharger and such. When I drove home I noticed my car wasn't Idle rough any more. So if get a chance check some of your hoses to see how they look. Don't know if you guys checked this on your cars but it worked for me I'm still gonna check my throttle body to make sure but just figured I'd put it out there

 

Yeah, you probably had a small vac leak in one of the hoses. Glad you got it fixed up though.
