Q: I need to take my 1997 nissan 200sx in for emmisions this year. I had the computer cleared so now i have to drive it for a while so the computer can read how the car is running. Does anyone know how long i have to drive it before i can take it back for emissions?
A: Lol full tank of gas and drive it. you need to fix the problem that triggered the light to begin with. if you dont, then monitors wont be ready, dont waste your money on a full tank of gas, any real mechanic would know that wont work
