both oxygen sensor s have been replaced the forward oxygen sensor 1 yr ago the other one 1&1/2 yr ago,
the past month, it was a rainy day i passed someone
my speed was around 80mph, couple of minutes later my check engine light came on and it scanned and it was the oxygen senso,i was told it could have gotten moisture from the rain, the code was cleared.i passed someone last night it was not raining,
my speed was 70 mph, about 2 minutes later the check engine light came on, had it scanned, i was told it was the oxygen sensor. i have put maybe 15,000 miles since the sensors was replaced. i do more town driving than highway.is this normal, is there anything i should do besides replacing the oxygen sensor. i also use shell regular gas
