VAFC **** turns green to red indicates lo cam changes into hi cam (Vtec kicks in).

 

ohh, ok so thats cool,
but as far as the motor not pasing 6,000 just like rev limiter effect, could it be the fuel pump?

 

no CEL lights?? cuz thats what happens wen u throw a code, the ECU goes into limp mode, and wont run properly

 

no check light

 

my car did a simular thing. It turned out that the vtec solenoid came unhooked. It never threw any codes, but the ecu seemed to go into this protective mode. I coudnt rev past 6000 rmp, but on my vafc light would come on to. I hooked it back up, and it ran fine.
