Answers :

Its good you took care of the basics
but you need to focus on the sensors that provide feed back once in closed loop

O2 sensors
Temp sensors
Knock sensor

that being said though...any of your sensors could be the cause because temperature can affect the sensors

then there is the possibility that you are dealing with a base engine problem too which may be affected by engine oil

LONG STORY SHORT...we need to get a scanner installed so that we can measure fuel trims and O2 readings

when you did the "tune-up" did you replace the fuel filter too?
