Idle Surge, Running lean? I took my car to get the codes checked at Auto Zone and I ended up getting 3 codes that popped up!
p0171
p0174
p0507
My car isn't slow or anything..... it just surges a little bouncing from about 900rpms to 1000rpms. just very annoying.
Any ideas as to what it could be? I have a lid, p&p maf and p&p throttle body.

So just a de-screened MAF right, hopefully you did not port it. Your car is running lean for some reason, seems MAF related. Try cleaning it with a MAF cleaner.
P0171 System too Lean (Bank 1)
P0174 System too Lean (Bank 2)
P0507 Idle Control System RPM Higher Than Expected

It sounds like you are looking for a vacuum leak. If there is air entering the engine that the maf doesn't know about it will run lean and go away off idle. Also check the IAC for proper operation.
