My babysitter's '99 Honda Civic HX (non-VTEC engine) had the check engine
light come on. I put the scan tool to it and got the code P1259 which is
supposed to be a VTEC malfunction. I erased the code several times and it
keeps coming back. Concurrently, after having had her clutch and tranny
replaced, she cannot rev the engine above 4K RPMs. It's like it has a rev
limiter that kicks it down. Any ideas?

Thanks,
