Hello , I saw your videos and feel they are all amazing , super good materials for me to know my car.
I recently got engine lights on , error showing p2188 too rich idle on bank 1,
And p2179 too lean idle on bank2
The symdrome happens sometimes ,not always, by luck or by no luck, I find problem when accelerating.
The engine just doesn't response to my pedal press. Even I press to the limit, the engine doesn’t response in ratio, like super tired , nearly no power . but if gear in 1 or 2, it can still go. if gear 3, not even able to move up slope.
if leave the car for a few days and back, it could resume normal sometimes.
What is the possible reasons you think? And what kind of stuff do you think I can test first ?
