Ok, I know there's probly a thousand things that could be causing this but what are the most common? Ive been in other cars with rough idles and mine seems a bit rougher. Its strange though, some days it will happen and some it wont. So any ideas on what my problem is? Could it be my CAI? Possibly messing up my air/fuel ratio. Or maybe waters getting in or something. I dunno...

Thanks for any help

 

It could also be the IAC. Check for vaccum leaks and check your idle speed screw. Don't know for sure if this will help with a rough idle, but I know it helps with idles that jump. Good luck.

 

Well its a start... thank-you

 

I am interested in looking at this too, but I swear my Helms manual and my engine don't have this thing in the same place. Does anyone have a picture/link I can look at?
