Hi everyone, so, i bought and installed MPFI spider injection on my track, could feel the difference straight away, it started working more powerful i would say, even sound. While installing, i noticed that when i wanted to drop fuel pressure before taking the fuel line of, the was no pressure in the line, so i gues, after shuting of the engine, fuel just doesnt stay in the line and dropes to tank straight away. I have a taiwan after market fuel pump installed, 280l power. Dont know if that may be the cause, or something else, but i still have the idle problem i described earlier. The engine works, but sims to may be not inject onse in some cycle.. May be its the pump, may be the PCM, dont know. If anyone have any idea, would appreciate!Here is two videos i recorded, you can see and hear, from the exhast, how it just stalls for a second in every some of a cycle.https://youtu.be/kCDyOP1qC6U https://youtu.be/HzucmfJvTcM
