Was woundering if anyone has experienced this...I installed a VAFC in my car..spoon header..spoon cams..cam gears..throtle body etc....after starting my car up the vtec kicks in noooo problem even after its been driving a little and say I get out turn off the car and get back in car still runs ok....ill be driving the car a while on the road for a long distance I go to bring the car past 5gs and it feels like either a fuel cut off or rev limiter kicks in and prevents me from going past 5gs...seems to me like it occurs after the car has been driving and warms up a little has anyone had this problem?? please help thanks
