Hello all. Finally saved up enough to get a 914. It's a 1974 2.0 in silver. I am working through a few issues. When I first got the car home it was hard to start so I did a valve adjustment and now it starts right up. The next hiccup is the engine runs very rough just above idle until it is completely warmed up. I checked the AAR valve and it seems to open when the car is cold. I took out the air sensor and it passed the olms and vacuum test. Replaced the plugs but the old ones looked good. Light grey in color. I could use some help if anyone knows where the two wires in the white connector goes. This is all new to me and the learning curve is steep (at least in the beginning). Any help would be appreciated. Thanks.
