Car running lean?

[DiabloRojoStang]

I've noticed my valves rattling when I open her up. Was told that my car is running lean and needs a chip and tune. Was told that it's because of my CAI. I've had the CAI for 3 years and the problem started pretty recently. Any advice?

I doubt the CAI is gonna make it run THAT lean...

It's probably about time for a good ol' Tune Up anyway.

When you installed the Cold Air kit did you put the screen back in?

is the screen needed? Just curious because I have been driving with mine out for awhile now and want to know if it's bad

The screen wouldn't fit back in so it ain't in there
