hey. im new to this forum thing so i dont really know what im doing but i have a 97 gs-r with spoon sport pistons in my 97 hatch. Im getting a p1259 error code (v-tec system malfunction). I cant figure out what the problem is and i was wondering if it might have something to do with the pistons.....would i need to tune my ecu??? im not sure. Any help would be appreciated!
