so, to start off this car is a rb20 swapped s13, the cluster (rb cluster) is my problem, also my idle, my cluster temp guage isnt working propperly it reads that its above the H when its actually at operating temp, the fuel guage reads all over the place, and when i drove home from work tonight, my tach was "bouncing"back and forth. so, my idle, i can figure out why my car is idling between 2500 and 3000 rpm? my throttle cable isnt tight, i tested my ect and it was fine? what could be causing this? ---
