I believe i have already fixed it. But im wondering even since i fixed the problem but didnt erase the code will the car still have synpthoms of the code because it is still stored? Everythings works as should i just noticed a decrease in gas mileage and still had the p0700 code stored and read that decrease in gas mileage is the sign of that code
