I have a 99 ls1 z28
when i first got the car a month ago i changed the plugs wires fuel filter put a k&n cold air filter on it and changed the oil then went from there.

my check engine light is on,i got it read at auto zone and it said failure over 80mph, low volts to knock 1 and 2, 02 sensors bank 1 sensor 1, bank 2 sensor 1 both above converters and it had low fuel pressure. i changed the fuel pump with a ac delco. that did not work so i took it to the dealer to have them read it and see what they thought.they read the computer and said the computer was bad they was for sure that it was bad i told them i did not think that was the problem they changed it and it was not the problem light came back on this time
both driver side 02 sensors so i changed them. then it said both passenger 02s then i changed them got it reset came back on again so i got it read again it said both knocks changed them reset the computer again it came back on and said 02''''s bank 1 sensor 1 and bank 1 sensor 2 and low volts to knock 1 and 2 sensors. I dont know what to do. All changes I have done myself but changing the computer
