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.

 

Thanks, I appreciate the help...I'll try it and see what happens.
