My engine is a GSR with a b16 head, and it has a p30 ECU.I have problems with my car as follows, the VTEC will sometimes kick in when in first gear, then it won't engage after that. I'm throwing a CEL either #20 or #22. I'm hoping this is a common problem or an easy fix at least. The first several months I had the car I had no problems with it at all. Then one day the VTEC started not engaging. It tends to leak a little oil but not much. Any help would be much appreciated.
