Vtec not engageing properly

[HiHiVti]

I have an issue that only started in the last day or so...the problem is when I bring it up to 4,800 rpm it crosses over fine but the Gos back out of vtec as the rpm still rises up to the 6,800 when the inlets start sucking air that's works fine but it's still kind of dropping in and out of vtec? Also about 2 days ago the fuel light came on and even with half a tank it still won't go off ... Would this be a fuel issue
