after replaced those parts no more code. I replaced the left and right manifolds because they have particles moving inside and the scanner reported a misfire on piston number 1 and 5

I replace the spark plugs, the O2 sensors and the coils before the manifolds

Ok, have you performed a compression test or a cylinder leak down test on these cylinders?

Customer: replied 1 year ago.
no
Expert:  Mike Kelly replied 1 year ago.

Since the system is not setting any codes, this would need to be the next step. This issue sounds like the issue is mechanical with the engine.

Customer: replied 1 year ago.
the car is running strong but when is running from time to time fills like when you press the brake just a little and let it go

Yes, these vehicle had a common issue with the valves and valve seats leaking and causing this issue.
