Default '99 Z28 M6 - Code P0171 Set

'99 Z28 M6 - Code P0171 Set ... Lean condition in bank 1.

Bank 1 would be the driver's side?

This will end up at an O2 sensor replacement?

There don't appear to be any leaks, bad connections or bad gaskets on either set of injectors.

Thanks

Bill

Doohhhh ..... or maybe the problem is just an inproperly installed air filter lid ! I had swapped in a new air filter this morning before I left for work. Suspecting that I accidentally disconnected something electrical, I just checked. Noticed that the lid was not fully engaged, fixed that and ....... no more check engine light. I'll clear the code and see what happens.

It's amazing how many times I shoot my own foot!!!!

Well, that seemed too easy. Still getting the P0171 code. Going to check the idle air control valve and EGR valve today.
