A couple of days ago my check engine light had come on. I took my car to the same dealership that I bought it from five years ago. There were a total of five codes upon the engine diagnostics. The first three have never affected the cars performance in any way, shape, or form, which were items that I knew about or caused the check engine light to come on. The first three codes were cruise control malfunctioning, the floater switch stuck in the up position, and an analog Onstar kit. The last two were the fuel pressure regulator and the failing passlock housing which I did get replaced. Today (Wednesday), my check engine light came on again. I am looking at the bill and the exact words that appear are "replace leaking fuel pressure regulator, " and, "replaced fuel pressure regulator & adjusted." Can a fuel pressure regulator be adjusted either mechanically or digitally/electronically? If someone could please review and advise, than as always be appreciated.
have the same problem?
