Guys last night I put on my 60 pounders and got a tune and everything seemed to be working right and later last night I got on it and immediatly had the car misfire p0300, and two injector codes p0201, and p0204, well long story short I recked the fuel rail and all connections and started car and it went and then died again only with no misfire. So I had the car towed to gm and I was putting my old stage2 injectors and harness in and the car started and ran no problem so I now know something is wrong with the injectors I got, any ideas? Left message with intense but not there saturday.

Bump for needing help.
