Hey Scotty I'm chasing my tail here I've got a turbo underboost code, cam position sensor code, misfiring, and now my car idles rough and sometimes dies. I've I started replacing the ground wires but still have the main positive terminal one to yet. My boost is intermittent and my gas mileage is horrible...could this be the unfinished grounds? Or something else?

You left out some information, such as model year and mileage.

Anything suspicious in codes or live data?
Turbo underboost,camshaft position sensor, fuel pressure regulator, a friend of mine said that it was a parasitic drain so we started replacing the big 3 but aren't finished yet. Sometimes my check engine light isn't on at all
