Error code
I have a 2002 Z06.
I just installed Kook's Headers w/o Cats, And NXT Step Catback exhaust.
I got the car tuned on a dyno about 4 weeks ago. After that I broke a valve spring and I replaced it.
Since this day the car has a gas injection problem or a air problem or...
The check engine stills on.
Sometime the check engine flashes and during this time the performance are worst.
The codes are P0200 and P0300
All 8 plugs are brand new.
The only other modification on the car is a KN air filter.
Somebody has an idea?

Have you checked to make sure no spark plugs were damaged during the install and that all the wires are seated fully onto the plugs? O2 sensors are plugged back in correctly, right?

Wow....nobody is biting on the P200? You may have one issue precipitating another. P200 suggests there is an issue with a fuel injector(or control circuit). If you have a problem in that area, it can cause a misfire. I would start inspecting the injector connectors and wiring.

Thanks Lucky,
I'll told my mecanic to check that first.
I'll also cut my X-Pipe and re-install my original Cats. I think it'll be better for the readings of the 4 O2Sensors. Also the car sound will be more appreciate by my neighboors
I think I'll have to re-program the Computer on the Dyno for the air-fuel ratio after re-install of Cats...
