gud am. i had my isuzu elf (4hf1 engine) coverted to the mechanical type(no more electronic components) because it was flooded and the electronic parts (ecu, injection pump etc.) was beyond repair. the mechanic who did the conversion changed the injection pump, throttle and other parts. what i noticed after the conversion is "mataas ang idling" and it is too slow(60 km max speed!!!)!i tried reaching my mechanic but couldn't get hold of him. i am wondering what is wrong with it and hope you could refer me to a good mechanic with experience in this kind of conversion.thanks in advance
