I put in a Air/fuel ratio gauge today using a guide I found from a link on this forum and it works but says my car is running really rich.

could this be true with:

UEL headers
pulley
intake
muffler


just wondering if i find the link i'll post it.

Narrowband or wideband? If you spent $50 on a Pep Boys a/f gauge, you just bought a pretty lightshow. They're pretty much worthless for tuning, for that you would need a wideband like Innovative's kit or the AEM UEGO.
