New to this site. I do have a question I hope some one can answer.I have a 2005 Chevy Tralilblazer ext,with the 4,2 engine, My check engine light came on. Scan shower P0014. I have replaced the vvt solenoid,and the cam position sensor. Everything was fine when the light came on,no rough idling,no stalling,fuel mileage was the same, It seems that after about 60-65 miles,the cel comes back on with the same code. I reset it,and it went another 75+ miles before it comes back on. I can't figure out the problem. Can any one help? Thanks very much!
