Just got my new motor installed jdm b18c. the throttle feels really hard to push open and it feels like it doesnt open all the way. Probably the cable.
the second thing is in 2nd 3rd and 4th gear the engine and tranny shake from 3000to 4000 rpm.
also It sounds like a pulley or something is freewheeling when im on the throttle. Kind of sound like when you pedal your bike backwards.
whats going on someone help me out please
