Lean Bank Codes
Am getting Codes PO 171 and PO 174 Fuel trim system lean bank 1-B and 2-B respectively. Do I take car to Corvettes of Houston for a fix or something a moderately capable home mechanic can take care of ??

Did you recently install a cold air intake by any chance? It's a common DIC code after that modification.
If that's not the case, check all of the connections between the MAF and the air cleaner, it could be as simple as a loose hose clamp allowing air to enter the system.
