I'm assuming we are looking at the back of the motor, left side are we talking ground one and eight on the right side around five on the left side? Neither of which you can see
I look at the history on my OBD two reader and it said fuel overload and air overload

G104 and G105 are the grounds you want to clean and inspect wires. #5 and #8 in picture. They are behind/below the intake manifold on back of engine. Let me know if you have more questions, thanks.
