Hello
I'm having problem with stock Camaro i got to tune, lot of problems and most of them fixed. Car is currently full stock and stock tune installed.
Some things made by prevoius garage
1. New vin matched injectors
2. New twice changed hight pressure fuel pump
3. New low pressure fuel pump
It was pig rich and oxygen sensors were not doing anything due clogged cats.
Now new oxygen sensors, no cats, oxygen sensors works correct and finally match wideband installed.
But cold it starts to -20 fuel trims and going to rich and rich with temp growing finishing at total of around -55 or so, still matching wideband.
Do you have any ideas?
I could try to "fix" the problem by injector tip correction, but that's just a "fix". My ideas finished.
