check engine light...
at 182,000 miles and countin my check engine light has come on. After plugging in the accutron obII diagnostic tool i get the following numbers po141, po155, po135. this meant that all my 02 sensors were bad. i replaced all three of them and this still happens(check engine light comes on!) i have erased the codes everytime i start the car and drive away. the codes do not come back untill i shut off the truck and start it again. the truck in the mean time has a slight stumble at idle that comes and goes. all other driving conditions are fine. plenty of power,getting almost 400 miles to every tankfull. what gives?

what people done understand is when a code is generated it pointing to a sensor or what ever that is not working properly due to something else. so what you need to investigate is why would the o2 sensors be having a problem???? what do your plugs look like, hows your fuel pressure at the rail. things like that.
