the O2 sensor used to set an error code occasionaly back home, but now it's driving me nuts.
yesterday i drove 650 miles thru a winter storm on my way to california. normal speeds on this trip are 70 to 85 mph depending on whether it's two lanes or four. at these speeds i only see the SES light come on when i had to slow down for traffic and wait for a chance to pass.
on this trip i had to slow to 50 to 60 mph because of weather. when ever i slowed to about 50 the SES would come on and go off again as soon as i picked up speed again. on and off for 13 hours. and i still have over 1200 miles left before i finish this trip and get home.
can anyone tell me where the O2 sensor is? can it be removed easily and cleaned or do i need to replace it.
