Thank you very much for your response,

The spark plugs had oil on them (I overfilled the oil a bit before) here is the picture of them, https://imgur.com/a/2ZL84Xy I changed them with NGK spark plugs.

- If I unplug the MAF sensor is that safe ? do you mean IDLE or should I drive it? is there a page I could see what is the Correct MAF and O2 Voltage Data ? (I I will go get them soon for you)


ps, btw my car does have small oil leak and does occassionally Yell at me at the "STOP engine oil pressure" (but there is enough oil in there, I get 28 Thermal Sensor or OilLevel Defect Error code which I think means oil level sensor is bad )
