miss34

thanks i was wondering what the steering wheel buttons do. now just have to figure out why it slows down on the highway when in forth my need a new solenoid

i recently just brought a r34 gt-t auto and it seems to have a few little faults. When on the highway every now an then the accelerator will stop working so its like you cant go up in speed it just slowly drops. Some times if you put your foot flat it will kick back in but lately the only way in fixing it is to put it into 3rd and wait a few seconds then put it back into drive. Does anyone no what this could be? Also slip will keep flashing on the screen?
