Has anybody ever had a problem with there camshaft position sensor? I have cel and my scan tool says thats the problem, so I ordered a new one. I just added the m50 manifold and software, I can't give a honest impression yet because the car feels real strong at times and sometimes it feels like it doesn't want to rev up. I was thinking that the bad cam sensor may be causing this erractic behavior with my car. What do you guys think?
