I need the tubes for the EGR valve that go from the exhsut manifold to the EGR valve. Got a constant check engine light because I had to remove them when I did my head gaskets. I couldn't get the tubes to come loose from the manifolds so cut them off. Thought I coudl get the car to run okay without the EGR hooked up. Now I just want to get rid of this damn check engine light and from what I've read, having the EGR hooked up should help it run better.
