Though the Oxygen (O2) sensor, the Engine Control Module (ECM) has detected a lean system, which means that there is either not enough fuel or and excessive amount of air in the system. Start by checking for vacuum leaks.

regardless of prior concerns here, we've got to go back to the basics, air, fuel, spark, timing----got these elements? we should start testing to see which component is deficient~

like my evil uncle would have me hold the high-voltage wire while he pulled the starter handle, we should check to see if it's sparkin'~

It is a challenging job to get to that oil pump which is under the motor inside the oil pan...the pan bolts must be removed, the oil drained and a new gasket will need to be fitted---now why are we doin' this? low oil pressure?
