I have to be honest, if it isn't a wiring issue caused by your work, I strongly recommend having a trained tech who has access to a scanner work on this problem. This can turn into a nightmare.
First, possible causes include:
possible open or short in oil control valve circuit (OVC) bank 1
OVC for intake camshaft bank 1
Bad ECM
Let me know your questions.
