I have been having a similar problem with my H22ed 94 Accord. For about six months after the swap was complete VTEC was kicking on hard everytime, no check engine light, and redline was at about 8200. Recently, the check engine light came on and now VTEC will not kick on anymore at all and the redline has decreased to about 6500 RPMs (where it was with my F22). The only code that is coming up is for an EGR valve. My mechanic checked the wiring and grounds and could not find anything. Replaced the solenoid, oil pressure switch, and swapped out the ECU and still no VTEC. Does anyone have any ideas? I would really appreciate any help.
