Hi, I have an Opel Astra 2.0 Turbo, I think its Vauxhall, and when I put the hks valve the check engine apear on my car, and the car dont work right.
How do I need to connect the valve so that symbol dissapear?
Do I need to cover the original valve or only taking the vaccum line from the original valve and putting it in the hks can work?
have the same problem?
