so my check engine light turned on twice after going more then 115-120mph , i had to smog my car recently so i thought a genius idea would be to reset my battery terminals so i could pass smog rite? lol wrong it didnt pass smog but the check engine light went away so the smog place couldnt tell me what to fix to pass smog. now i have to figure out what it is because ironicly it wont turn back on !!! plz help on what the problem could be? thanks alot
