I removed the smog rails from my 2.0, blocked the air pipes with caps, and reattached all the vacuum lines - used the diagram for '73-'74 2.0 that is available here or on PP or ???. Anyway, car idles fine but loses power around 3k and backfires on decel. I do have a bit of an exhaust leak at the heads (new gaskets ordered)
Just wanted to verify that I have the vac lines hooked up correctly. Once I know that I plan to get all new lines as well as get rid of any exhaust leaks. Click on picture for larger image. (IMG:http://www.volksbraggin.com/porsche/vacLines_1.jpg) TIA. |

One thing to note: Since that diagram was made, we have come to the conclusion that the larger hoses (colored blue on that diagram) to the Decel Valve need to be swapped; the one plugged into the side of the DV should go to the air cleaner, and the one plugged into the back of the DV to the manifold.
