Hi, I was wondering what the circuit board on the side of the throttle body actually does? I recently had the problem of loss of power after the engine had warmed (roughly 10min from cold start). When the temperature gauge reached roughly 1/3 of the full scale, upon acceleration the engine would be starved of fuel and would jerk violently. The engine would idle roughly but the fault occurred mainly when the accelerator was pressed. I solved the issue by resoldering all the joints on the throttle body circuit board and now I'm curious as to what the circuit actually does??
