weird idle and sudden engine fan operation
does anyone ever experience a sudden shake or idk what u call it , but the engine starts to shake out of no where at idle (only sometimes ), and the fan also sometimes starts to operate even when im just cruising , i live in a hot country so maybe that explains the sudden fan operation?

I had a similar problem that I posted up here. I would approach a stop or come to a stop, the engine would shudder and then turn itself of. One occasion I let it shudder turned the car off and it wouldn't turn back on.
After replacing some relays in the rear, the problem was still there. Then the dealership replaced the battery and the car has been running fine since with no shudder whatsoever.
