Hi.. my x-90 has been acting up a bit, the other day i went on a 1km uphill run and it worked fine going up...on the way down the road i coasted in neutral alot and when i hit the main road and applied the throttle it started skipping badly. On another occation i was driving around the comunity and again it worked fine, then all of a sudden it started bogging out like anything past an idle would bog out completely. I unplugged the sensor in the air breather and it started working again just fine until yesterday it started skipping again, anyone have any suggestion on what to try ? ...the first time it seemed like a gas problem but now i'm not so sure. This is my first zuk and i'm not familiar with their behavior yet . Is that my fuel filter right above my tank, can type looking filter ?
