either the lift pump or the injector pump.the injector pump is very expensive to replace.it costs anywhere from 1800 to 2500 dollars just for the pump.I found someone to rebuild mine for 700 dollars.
no
Sounds like it's running lean. a fuel pump, or related issue....
No
If the 2003 Focus is running good then suddenly shakes and looses power, check the fuel system for proper pressure. If the pressure is correct, check the ignition system for fire, the ignition components could be starting to fail.
Fuel Pressure
Need to run a fuel pressure test, and check the fuel filter.
If no codes (check engine light) or rpm fluctation first check fuel pressure
It will burst. It is selectively permeable to ensure that only the material that is required in the cell is able to enter it, if it looses the ability to to be selectively permeable then difusion will occur and the cell with try to be equal to the outside pressure, which will likely cause the cell to burst.
i have the same issue. the radio is bad and is shorting out. it is running my battery down every 3 days.
It looses air therefore, you have a flat tire so you should go to a mechanic! The tire pressure slowly drops causing the tire to wear unevenly and you to have less stability and control of your vehicle.
High pressure tells me of a possible head gasket problem. Have the cooling system pressure tested by a reputable garage; this will answer some questions.
