Hot air turbo power with digital boost

Replaced wastegate vac lines. Prior to replacing lines the digital boost was working but at times it would only show orange or only show red, or show red before orange which still does. Sorry I don’t know the technical terms. What could be causing this? There was some evidence of oil in the old lines. I also replaced the PCV valve and added a grommet as there wasn’t one. But the new grommet doesn’t seem to seat into the port. Was that a mistake? Car is all stock 84 GN driven very little for the past 25 years. Overall the car has been running better than I ever remember but the power is inconsistent. Thank you.
