Someone please help me?!? I scanned my computer with a MAC Tools scanner and it read codes PO171 and PO174. My engine light intermittently goes off and on. At first, I thought it was an O2 sensor, but it looks like it may be something else. What does that mean what do I do to fix it? Thanks.

According to http://shbox.com/1/Dtcs.htm

You are running lean in both banks of injectors.

Shot in the dark but maybe your fuel pump is going out? Ask the LT1 tech guys they will know.
