I was driving to school this morning and my check engine light came on half way there, i notice the day before my car seem to be lagging a little..got the codes checked,had 2 codes it said fuel is running to rich and too lean at the same time....anyone ever had that problem?? im thinking i need to replace my fuel filter and clean the injectors..also i believe i got some bad gas..thats what i think but id like other opinions
