8.1L ... Fuel too lean in right and left bank
Diagnostics is saying (1) mass air flow problem (2) fuel too lean in left bank and (3) fuel too lean in right bank. This happens intimitantly and causes the "check engine light" to appear. What is going on man?
I have installed various bolt-ons i.e. flowmaster, JBL headers, K&N, throttle body spacer, hypertech. Am I sucking in too much air for the fuel mix or do I need a better fuel pump? It seems to me the on-board computer just aint getting the mix right!
