I'm driving a Ford Ltd with a windsor V8 on deul feul petrol/LPG I have changed on it the feul pump, feul filter and new feul injectors. Well on LPG it's ok,but on petrol it starts, run on idle ok but when put it gear it seems to loss power it stalls.
Any help Please

Most probably have partially blocked injectors, or maybe a lazy MAF sensor ( gas backfire ?). Rip the injectors out and get them ultrasonically cleaned and flow tested. Mike

Thank Mike for that promt response, where would theMAF sensor be on the engine, and the feul injectors are brand new is that nessesarly to clean them.
Thank You
