2.0L turbo charged engines may develop a hesitation on acceleration and/or illumination of the Check Engine Light due to a failed high pressure fuel pump or a worn camshaft follower or camshaft. Our technicians tell us that whenever the high pressure fuel pump is replaced the camshaft and the follower should be checked for wear. The camshaft lobe pushes on the follower to operate the high pressure fuel pump. Frequent oil changes and use of synthetic oil may help with this wear issue.

Everytime I press harder on the accelerator to pass someone or after a red light the car hesitates and there is no power. I used my code checker becaus e the engine light was on and it gave me several codes but mainly the cam follower code. I bought one for 30 bucks but i have no idea on how to replace it. I also bought a fuel filter will replace hopefully this weekend,
