how could you not notice that ??? plus vtec hits @ 4400
anyways i had the same problem and it was my vss. certain 95 jdm b18c had a recall on them. so if you speedo wigs out sometime its your vehicle speed sensor. but im probaly wrong.
just make sure thats it i bought a new ecu too and that wasnt the problem to bad i sold my old one or you would have one huh ?
good luck there exspensive !
