THat is an interesting symptom for a blown Overvolt Protection Relay fuse... revs not more than 5000 rpm! Interesting.
Has your car been jump started or have you jumped anyone recently? That is what *usually* blows the fuse.
Glad your problem was solved and for cheap! I wish you would have let us known about the ABS light! Then we probably could have told you to check the fuse!
