How do you KNOW it isn't "cracking VTEC"? Are you throwing any CELs? Can you rev past 5500RPMS?

Yea I can rev past 5300 and I dnt hear the crossover(I know its not as loud as a dohc) and yes o2 sensor

Sounds like it's working to me.
You can get a P2P ECU and an adapter harness but I doubt it will change anything.
Fix the CEL.

Ok thanx

But what about the vtec not cracking is it cause the cel light is on?

Fix the CEL.
I think VTEC is working just fine. Can't feel it on my car.
