Here is the problem with my baby (92300ce)...
Slight hesitation when applying throttle from idle. when kickdown, see a puff of black smoke. Seems like the symptoms of engine running rich.
So, I brought to a mechanic. The guy said it is becoz i put a high octane gasoline (97) that damage the fuel distributor unit.
Is that right? Spending more money on "better" gasoline only to damage the engine?
