Hi all fellow Pelicans,
My Porsche 928 S2 from 1985, is running pretty stable in IDLE and in general seems to run also fine when driving around.
But there’s a smell behind the car (coming from the exhaust) that it seems to be running rich. And if a friend is driving behind me in his car, he’ll typical when we stop and talk say “your car smell like an environmental hazard”. :-/
So it seems the problem is there also not only running in IDLE.
Does any one know of a “checklist” of stuff to walkthrough for finding root cause of such a problem?
I did already change spark plugs, ignition caps/rotors, air filter, engine oil, water pump, timing belt, coolant.
Thx in advance.
BR
Chris
