My Poorman acts like it wants to stall out on a stop light. I open the hood and looked at the cam gears and its not spining normaly. When it would want to stall out the cams spins slower, plus i also feel that my car has lost power. Ive recently changed the clutch/flywheel and fuel filter. I open my buddies car and his just spins faster than mines at a constant speed. Can timing be knocked off on its own?

 

now i got a code 9(CYP) and 41(o2)
