Ok, here it goes. I bought a 914 1970, EU 1.7 D-jetronic. Off course it didn't run. I did some work on the car & engine -> other topic
But I don't get it to run smoot. I'm not an idiot with these engines, now how they love to have no vacuum leaks, valve adjustment etc etc. I've read a whole lot of bowlsby pages and every other article I could find on the net. But she just doesn't run smooth.

What I know for sure:
- valves / adjustment / compression -> OK
- trigger points and adjustment -> OK
- wiring -> OK
- injectors checked -> OK
- tried different Ecu's -> no difference
- tried different MPS -> no difference

What doesn't work:

She starts, but I've the feeling that she runs on 2.5 cilinders.
Lack of power except, sometimes around 2000rpm, she flys
Sometimes she runs good, and all of a sudden, crappy.

Where to start? Anyone nows these symptoms? And NO I don't want a carb!!!!!

When you checked the fuel injectors, did you check them electrically? Did you check their spray patterns? Also, look at the grounds for the injectors....could be the connectors aren't getting good ground due to dirt or looseness. Also, how are the wiring plugs for the injectors themselves? Sometimes they get loose and cause injectors not to fire properly. In addition to the spark plugs, do you have good plug wires and ignition items such as points, condenser, rotor, cap on the dizzy?
