I have a pajero GDI and it start make me problems with the acceleration. When I m driving it start losing power and when I press the petal violent it start responding normally. The diagnostic dint show me any problems, the engine light and the others are switch off as normal, but the fuel pump pressure range between 4.0-5.0. Any ideas?I clean the throttle, I check the sparks, and clean the mass flow. Any ideas to help?
We don not have any information on your vehicle and if I am not mistaken, it uses a fly-by-wire throttle system. As no trouble codes are ptresent, the only way to find out is to use a scan tool to monitor the accelerator control and throttle to check if anything is working out of specs.
