P0442 Smog Check
I cant pass smog check with check engine light throwing this code P0442 (small evap leak detected).
I ordered a new gas cap, if indeed it is the gas cap will the check engine light void itself immediately or
would I have to complete a new drive cycle before the light goes away?
Every time I need to smog the car, I get a code saying that a small leak is detected, whats up w/ this?
Anyone else constantly dealing with this nightmare?
