I checked my vaccum lines and I realized they were leaking in about 8 different places, so it's definitely time to change them out. My question is - do broken vaccum lines rob power off of NA cars? I've asked a few people and they tell me that the power losses are mainly prevalent on turbo cars...

 

It can cause power loss. Probably not as much as you think though..

 

So what, like 2-3hp? These vaccum lines are REALLY shot.
