i have the vafc hooked up on my 92 gs-r. when the vtec hits though, the car starts boggin down... we took my vtec soleniod off and cleaned it hoping that it would be a quick fix, but it still does that. i was wondering if anybody knows what everything should be set on the vafc to make it run stock?

 

take the vafc out. that'll fix it.

 

or u can try hooking up the wires correctly on the ecu, i havent heard of anyone having a problem with their VAFC II, mine works just fine.
