Hi guys finally decided to make a post about problems I've been having. My trailblazer has had a rough sometimes sporadic idle for some time now and just recently a p0014 code popped up. So I did what everyone says to do, cleaned the throttle body, put a full can of seafood at fuel up, changed the oil, replaced the camshaft position sensor, and then replaced the cpas but check engine light came back even after I reset it. Both sensors are duralast if that makes any difference which i doubt. I've heard that it might have to do with the timing chain and tensioners but with 133,000 I doubt they're bad and wouldn't spend any money replacing them. That being said I just can't figure it out and I'd love some advice from people who have solved this problem

Rough at Stratup

I have the same rough idle, but just at startup. Once the engine warms up, everything is good. Code is a P0014 and I have not replaced anything yet. What did you end up doing?
