Weak VTEC???
I have a 99 Civic with a 99 GSR engine converted to OBD-1 using an OBD-1 P72 ecu. I was talking to my friend and he says he thinks I have weak VTEC. He says that could be caused by the secondary butterflies not working properly. I mean I can hear them kick in everytime I take it to high RPM's so to me they are working properly. Is there anyway I can find out if they are not working right or if I have weak vtec?
