I have a 2001 civic si and im having problems, the car died and will now only rev up to maybe 2000 rpms when this happened temp guage and rpm guage stopped working tried a scanner couldn get a reading tried to use self diagnosis check engine light doesn't blink at all im stuck and want to know what to do next or if anyone has had this problem, your input is greatly appreciated

 

Sounds like the car is in limp mode, the problem is figuring out why it got put into limp mode in the first place.
