Picked up two new sensors from Dan last fall and installed them, no problem. A few weeks ago I get a 71 EGR cel, banged on it and cleaned everything up and reset. Then a week later got a 71 and a 26. I put a couple cans of Red Line in on the next two fill ups and things were running very good. There was considerable stumble and it cleared up after the RL treatment. I let that go for a week and reset it today and get a 21 for the #1 sensor as soon as I start the motor. Does any of this make any sense to anyone besides trouble in river city and I need a new #1?
Has anyone had a O2 sensor go bad in that short of time?
