Dear 914ers,
I'm quite in a pickle with my 914 1.7. The engine sometimes starts sometimes not (usually after it started, ran 5-10 seconds and then stopped and I couldn't manage to start it again). Messing arround in the engine compartment I accidentally unplugged the cyl 4 fuel injector and surprise the engine started and idled low. Tried again one, two, three times and he started succesfully, but as soon as I plug back the cyl 4 injector cable does not want to start again... What's wrong here? (the injector not, because I've swapped 3 with 4 and I still had the same problem). According to the attached current flow cyl 4 injector is in series with the cold start valve and the thermoswitch for the cold start valve.. Am I looking at the right diagram? I also don't know where current track 102 comes from. Also very interesting is that I removed the injectors 3 and 4 and placed them in two cups to see if they work, and I could start the engine in two cylinders (although the cyl 4 injector plug was connected) Cheers, Bogdan Attached thumbnail(s) |

Have you checked all the shift rod bushings?
One in the front shift rod support bracket under the shift lever assembly in the tunnel One at the fire wall One spherical on the shift pivot bolt at the connection to the rear shift rod One spherical in the front of the rear shift rod One in the rear shift rod support bracket EDIT: The condition you describe is pretty common when the bushings need replaced. Mark the positions of the shift rod connection at the rear of the tunnel prior to disassembling anything. It will save you a lot of time getting the shift adjustment back to normal.
