2004 GMC Envoy 4.2v6 check engine

Question

The check engine came on the codes were for a cam senser and thermast senser. Replaced both and the check engine light came on again with the same codes. What should I do now.
Thanks

Answer 1

What are the codes? Did you replace Cam sensor? and the code came back on? do you know what speed, the reason I ask is that you have a cam actuator that uses oil pressure to control exhast camshaft timing, On your particular vehicle these actuator are famous for plugging up and causing rough idle, the cure was a replacement or pop it out and clean it out using brake cleaner, and stick it back in, can you give the other code that you have?
