I just did an engine swap in my 89 760T and the new engine is not idling properly. It is sometimes hard to start and then it will idle fine for a few seconds and then skip...then the skip gets more frequent and eventually it will stall.

I replaced the fuel fllter, spark plugs, fuel pressure regulator, and injectors and this did not affect the problem.

I am not guess in it might be dist. cap, rotor and plug wires....and I on the right track...or should I investigate something else?

Thanks
