I need help with my civic, I bought a old 85 im gonna race in the 24 hours of lemons race, and I need to get it running right, this car was sitting for a long time, so I put fresh gas and plugs in it, and it runs crazy!? I dont know what else to do? Also i want to know what vaccuum lines I can take off, i want to get rid of all that, i dont need any emmissions or any extra everything can go that doesnt make it run basically>? It has a ton of them, and I dont need any of them but scared to rip them out till I know what I do need? Can someone help me with this>? Thanks!
