Engine emissions system Problem
My engine emissions system light in the dashboard. Bought it in to dealship. Said they fixed it. Guess what it came back . They said it was a cmp sensor a and ckp incorrect phase . Clear code and check .

So going to bring in back . Try some yelling . Starting to be a normal when visiting the dealership .

And the vsa light appeared with the engine light on the second time . Sbeijing to dealership get more problems . Seem like a bad cycle too me. Good for the dealership.

What are others they will cause now

 

My light came on this morning... so what is the main solution? should I pay lots of money and bring to dealership? or is it something i can do myself or bring to an autoshop? thanks
