DTC P1336
 

I have always been able to fix a problem after knowing the trouble code, until now. I have replaced both the cam sensor and the crank sensor. I still get the trouble code and experience the same problems. I was hoping some one would have some suggestions on what to do next. Am I doing something wrong or missing something?
Thanks.
