i have a 97 ws6 ta and i bought it used and it had already been modded out. my question may sound dumb but should there be vacuum lines coming off of the opti. it runs fine dry but as soon as it rains it starts to run like crap. there have never been any hoses hooked up to the opti so if there should be please tell me were exactly they are run. i believe there are two one is very small and the other would probably take like a 5/16 hose. thanks

 

It depends on the year of your car. 93-94 are non-vented so they do not have vaccum lines coming off the opti. 95-97 are vented and should have vaccum lines coming off the opti.
