Hello everyone, I have a problem that I would like to solve since I have been 5 months and it has not improved that it is the rich mixture, it turns out that I changed the cylinder head and changed a turbo td05 and after that the car was burning too much fuel , the wideband in 2nd is already marking me 10, but it is strange because in low gears I can disengage and accelerate slowly and it marks me 14 (wideband) not like that when going 45 miles up, already there it marks me again 10 and one great loss of power always.
this is a video of the parameters that marks me


The lambda sensor was changed, the injectors were cleaned and it does not improve. bujias y cables nuevos, junta culata cometic

I would greatly appreciate your help

my car is a 95 year GST eclipse
