What does it mean to have an improperly tightened gas cap?
Could the improperly tightened gas cap be the reason for the check engine light staying on or flashing?
I suspect that my 1997 Toyota Camry has it's original gas cap.
How many turns on the gas cap for proper tightening?
till it clicks, and your just guessing it could be the gas cap. Have the codes scanned at your local auto parts store for free. Post the codes back here.
ok thank you
