Well, I thought I had this licked, but apparently not. My 1974 914 with the 1.8 is giving me a weird problem.

Once it is warmed up, it will run fine for about 15 minutes, then when you try to hold speed, the engine will just completely die. In about five seconds, it comes back. After this happens, it won't hold idle any longer either. Before, it idles perfectly. It repeats this until I shut it down for an hour.

So far, I have moved the fuel pump up front.
Replaced fuel filter.
Replaced all ignition components except distributer.
Replaced injectors.
Found and fixed all loose connections in FI harness.
Cleaned and checked throttle body.

The throttle body was full of oil and grime. and the butterfly seems to be actually dragging on the body so, I guess I will be replacing that too.

What I fear is this is an ECU problem..

Anyone have any ideas??
