Hello to all forum, I see that this forum has a lot of news on Marea and maybe can help me with my problem, recently my car had blown engine, I've had good grinding, but do not understand why when the car gets hot loses the strength and time delay to start, hopefully help me in this fight, since I changed the (MAF) and the fuel pressure regulator, and not yet resolved the question of delay in the operation, and the car is still weak when the temperature rises.
