Today while i asked to re-check the throttle body harmess, as i want to order one but it will take a while for it to ship here, i turned the car on without the covers or the air filters and the cars rpms were jumpy, there was a hiss sound that was happening when the rpms went higher and stopped as they dropped to normal levels, then they would drop to slightly below 500 and back up.(this happens always you can see the rpms often jumping) Monday they’ll check, i think that might be causing the issue. Considering that the car has been checked by two dealerships and multiple shops and none noticed..
