Hi, I'm new here, I'm a mechanic, I have trouble detecting the fault.
The car is a Ford Focus 2008, Zetec Rocam 1.6 engine, the failure is in fourth when you stretch a lot, but more in fifth when you get to 110km. What the scanner throws is P300 and P304. I changed coils, spark plug wires, naphtha pump, replace fuel, I made cylinder cover and rings for low compression doubts. The exhaust also probe. That waiting for your answers, thank you very much, a month ago I disagree with the car, even check with mechanics in the area and nothing ...

Good day Matín, the faults in high of this vehicle are usually the gas filters both the one that brings the pump internally in the tank and the one that is at the exit of the tank, change them and you will see the improvements. I have an 2006 and it presented the same fault as yours.
