okay, heres the problem. i have my vtec crossover point at 4500 rpm, but when i start driving, the vtec controller drops the vtec crossoever point to 2000 rpm. i reset it, and after a few minutes of driving, it does the same thing again. it was not giving me these problems before, but all of sudden, it started doing this. anyone have any ideas of what it could be? what wires should i check for?
