Good evening to everyone i have a very Big problem with my Ford Escape 2002 I have this problems code: P0305 accuses Cylinder #5 P0306 accuses Cylinder #6.
I already change the gasket i buy the felpro Kit, and i Also replace all the sparks and spark plug boots, I clean the air sensors and i also replace the EGR, i try to switch cables, and all is the same the car start buy when i accelerate it just go off, i don't know what can i do next, somebody told me to change the fuel injector, i take the pressure in both spark holes the number 4 was 150 and the 5 and 6 was 120, No leaks oil.

Somebody can help me please? i don't know what else try
My car is a Ford Escape 2002, XLT 3.0 4x4

 

I think I read somewhere that the wires can be swapped - Cylinder 5 wires mounted to #6 and visa versa. You could have had bad spark plugs or boots and inadvertantly swapped the wires during reassembly. This could explain both codes.

 

You can try swapping the COP (Coil On Plug) from number 4 to number 5 or 6 to see if the misfire follows the COP. They can fail, causing misfire.
From reading, you have replaced the plugs & boots, but not the COPs, correct?
The compression readings on 5 & 6 are a bit low. Did you try adding a tsp or Tbsp of engine oil to the cylinder through the spark plug hole and re-testing? The oil would temporarily seal the piston rings if they were troubled, and increase effective compression. If you did that test, and compression stayed the same, then you could diagnose the problem as being with the valves with a bit more assurance.
I don't know if 120psi is enough to get good constant firing to prevent misfire at idle.
