Ok first time I got my exhaust on and started my car, it had a bad idle surge. I was told it was a vaccum line. So when I checked I forgot about putting a line on it. After replaceing the line the idlewent down greatly, but is still slightly there. When you hit the gas in not only gets worse, but feels like it's loseing power. Only thought I had was the throttle body. But im not the best person to think about stuff like that lol. Anyone else give it a go?

 

Are you talking about an exhuast, or an intake? There are no vacuum lines that run to the exhaust

 

no, there was a line that went from the intake manifold to the block. My motor is a D15B8. I put a full exhaust system on it, and a new intake system.

 

Bump, I still need help!!
