SES Light diagnosed! So I took it to Auto Zone and had the light diagnosed!
I actually had 3 come up.
p0171
p0174
p0507
I have a ported and polished tb, ported and polished maf, and slp lid.
My idle surges a little bit from about 900 and spikes to 1000. No loss of power or anything and it ran a 13.1 last Saturday so I'd hope if I can figure these out it will be faster yet??
It says something about running lean in banks 1 and 2... and something about malfunctioning IAC sensor??
Any input? Thanks!

if it is surging, you most likely have a large vacuum leak hense p0171/p0174, the idle air motor is going crazy trying to smooth the idle and is most likely out of the operating range of the iac. possible intake leaks??? have you done anything to it recently?
