Re: Check engine light...
Check engine light came on every time since about two years ago. Month
ago before I was going to replace original gas cap on 98 S-70, I tried
to oil gas cap gasket and it WORKED! It could be that old and dry gas
cap gasket leaked.
I spread out one drop of oil all over the gas cap gasket. Q-tip was
handy. Then I filled the tank. Few days later, check engine light start
to work as supposed to.
