first you need to try all the same suggestions from your other misfire thread: https://chevroletforum.com/forum/equ...e2/#post491697
And post any other troubleshooting you've already tried.

I have switched the coils and plugs haven’t had a problem and now still getting po303 which is making traction control off light come on flashing engine light and feels like power loss. Anyone have a idea why this is happening?
