ok another problem i just found out. the 2 lines that are vents for the opti are switched and prolly have been like that idk for a long *** time. the one that is supseod to goto the intake manifold just goes to the intake elbow and the one that goes to the intake elbow is going to the manifold. so would that cause any type of problem other than not venting it correctly. like would just switching them make the car run worse somehow?

 

Should make no difference, all they do is to circulate air inside the Opti.
