How about Jovanny and Honduras
my name is Miguel. I am from El Salvador.
I answer your questions in order I hope it's not too late.
1) I have a Frod Focus Year 2000 Motor 2.0 LX Split.
I can tell you that it is an excellent car when you give the maintenance that the owner sends, the noise in your engine already lived it and it is a bus that is worn the packaging, and it does not reach enough oil when it is cold, you have to change, it has to be a mechanic that knows,
2) This problem is given because the gasoline pump is already very old and dirty and does not reach the gasoline well to the injectors, since these cars work. Injector, you have to buy it, at my cost $ 108.00 dollars plus $ 20.00 of the installation, and I put a bona of the Ford Explorer and I no longer have problems.
I hope it helps you.
