service engine soon light?
Hey guys i'm at 16385 mi and just put in a helix hfc helix dp and i already had a greddy ti cat back and my car just threw the service engine soon light so what does this mean? is this the same as the CEL because i have the mechanical cel fix. I've had the parts since thursday so i'm not sure what to do because i haven't had any problems yet.

id say its most likely the p0420 cat operating below thresh hold or whatever it is but none of us can really help you until you get the code pulled.
