Just fitted another RB20 to the cefiro, it starts first turn, idles perfectly and smoothly, the problem I have is that it rises thru the rev range slowly - like it has a blocked Cat or something, but exhaust is straight thru system!!!
Have replaced injectors, plugs, AFM
ECU Diagnostics show "55" (a first for my car!!!)
any help leading to the solving of this problem will lead to a cash reward!!!
