Chimaera 500 help needed
Discussion
Dear forum,
Chimaera 500, year 95, Serp. Engine
The following symptoms: At cold start after 14 days of standing, not all cylinders run smoothly, but this normalises after a few throttle strokes. Not unusual according to Mr Pohlmann from ACS Germany.
Then, however, after approx. 45 minutes of completely trouble-free driving, sudden loss of power, uneven running on not all cylinders, slight smell of unburnt petrol, jerky throttle response. After approx. 1 minute the phenomenon is gone again and it runs as if nothing had happened!
Replaced so far: distributor cap and finger, ignition cables, plugs, plug extensions and stepper motor.
I know that remote diagnoses are always tricky, but perhaps someone has already experienced a similar phenomenon and has a solution.
Perhaps the concentrated forum knowledge will help.
Best regards from Hamburg
