Hi I just recently bought a 99 corolla and I have a few issues with it for one the other day when I used the turn signal the headlights flashed off for a few seconds and now when I try to get in the car at night they come on and go back off a few seconds later even in the on position. I can turn the car off and back on and they come back on for a few seconds and dob it again. And second I've read its poses to get 31 Mike's to the gallon but I'm doing good to get like maybe 15 if that
