First post sorry if I screw it up. Bought my car about a month ago. CEL came on 2 days after I bought it (surprise, surprise). Pulled a p0411 off of it at auto zone. SAIP was working great so I started looking at other issues.
The idle is a little rough so I changed the spark plugs and the CEL vanished. Didn't fix the idle though. I think that CELs go off on their own eventually just wondering if there was any connection.


Also going to clean up the throttle body tomorrow and see if that helps the idle. Any ideas, suggestions, comments, concerns are appreciated. Thanks in advance.

 

Bump.

 

while you think your sai was working great, odds are you have a big hole in the line at some point. its the usual suspect
