Hi All,
Finally got my car running better 74 914 2L FI. Thanks to all for suggestions. It turns out it was most likely the main power wires loose to my battery (fixed). Fuel was on and off. I noticed something else when setting my idle. When I turn on my headlights my RPM's drop. I recently acquired a 912E and it does the same thing, though not quite as much. I attached some pictures, just because I like threads with pictures better. A. Could this be my Battery? B. Grounds? C. All the above? D. Other_________?    |
