toycar

hi, im new to the forum and after a lot of searching i've only come to the conclusion that when the cel and trac off lights are both on it is not a trac system problem? anyway, i connected pin tc and e1 on the dlc1 and got a code 61 which is for a bad engine control system. the description was VERy vague on alldata. the car still runs fine and has about 55k miles on it('00 es300). can anyone give me anymore info on this dtc? would getting an obd2 code reader help more? thanks
