Misfire
I have a 2010 camaro 3.6. Swapped the engine when I got it because the old one had broken rockers so I bought a donor car with a seemingly good engine that started and ran fine. I have the new engine in and it starts and runs fine for about 30seconds, then it starts to idle rough, but when you step on the gas it seems to smooth. I am getting misfire codes on cylinders 2, 4 and 6. Also the scanner reads no injector command on those cylinders most of the time, but every so often the scanner shows the proper injector command and it runs fine. Not sure where to start.
Thanks
