Question about Mitsubishi Cars & Trucks
Mitsubishi shogun pinin 2.0 GDI 2001. Car starts ok,idles ok but will not rev above 2000 rpm when accelerating. I have already cleaned the throttle body and replaced the microfilters in the high pressure fuel pump i have also stripped and cleaned the injectors and also replaced the microfilters in them too. i have replaced all spark plugs and checked the coils for correct operation i have changed the airfilter and the MAF meter. i have had only two dtc flag up p0190 which is low pressure in the fuel rail, i changed all filters and cleaned out the fuel rail and the injectors and this fault has now cleared the other code was p1221 which only came up once and when cleared never came back. it will rev to 4000 rpm if i press the accelerator very slowly but wont go above 2000 if i press it down normally, also the engine pops as if its misfiring when i press down normally but does no when i press down slowly any ideas???
