I have a cel I can't get rid of in my 2.2 CL. I don't remember the exact code but when I hooked it up to a diagnostic scanner it said "Insuffient Air Flow". I bought a new EGR valve and took the intake manifold off and cleaned it, but the code is still there.

What else could it be?

 

something on your intake isnt connected

 

mine said that and i got a new cat and ignition system for free, as well free oil and filter change and a crappy wash

 

Go to Autozone, et al, determine the code, and repost the code for some help.

good luck
