Yesterday while driving home I discovered my car had the inability to rev past 3k RPM. It seemed temporary but then on the way into work this morning it returned, along with the check engine light. Searching the internet seems to show that my car may be in limp mode, possibly due to a bad knock sensor. This may be right, since I did drive through a rather large puddle while merging back on the highway, but we won't know until Thursday when I bring it in for a previously scheduled scheduled service appointment.
Have a Golf that is very likely over 3000 RPM for your Monday morning.
