Dear all
I had a S4 a year ago, recently I ran into a engine REV issue. When I normal riding in 1-4 gears, the throttle turn smoothly, but the RPM can only go up to 4000-5000 then stay there, can not go up higher. Unless I ease the throttle a bit, then it will go higher then before.
The video I took is in station. It's the same situation when i riding. Video @ the 15's I turn the throttle, the RPM can only goes to 3000 then goes down, but my hand still turning the throttle.
Anyone can identified the issue? my local shop can not help alot with this problem...
