Disadvantages of the Peugeot ES9A engine
The majority of engine issues are linked to using subpar oil or gasoline;
Candles rapidly deteriorate due to poor fuel, and the ignition coils follow;
There are four types of lambda probes that fail for the same reason.
Many people put off replacing the expensive timing belt, which requires a significant overhaul, because non-original grease frequently leaks from gaskets and seals.
