I have an 87 Iroc with a 5.0/ 305. When I get it started, it begins to accelerate automatically. I have read quite a few forums and the one thing constantly in common is vacuum line issues. I have three below that I need to know what they go to so I can eliminate vacuum as an issue. Thanks in advance for the help.

the one in the top pic is the heater controle modual. thats a decent leak. and it goes fron the passenger firewall area to the modual. then the bottom pic is just the smog pump not a vaccum leak.
