Check Engine Light

[StanHolder]

Hi everyone, Check Engine Light came on yesterday. The CTS2 brings up P0108, P0073, P0106, P0069. No driving issues. I just noticed it smokes a little after start sitting at idle. No upgrades, 205,000 miles. If I clear the codes the P0108 and P0073 are still there. any ideas
