well cleaned up everything and truck seemed to start better but still rough idle and the same p0470 code. so ordered the sensor from oreillys and it will be here in the morning.

put the sensor on and got rid of the code but truck still idleing rough and shaking.. upon farther inspection the pig tail harness is all burnt up and brittle. so now trying that next..

Not sure what "tube" y'all are talking about but one thing you might want to check is the valve cover harness. One of the plugs fried on mine a few months ago and I was only running on 6 cylinders and it ran real rough. One of you plugs could just be lose and that is why it comes and goes.

Sometimes I am just that good. LOL at least you got the code erased.

Well replaced the pig tail and its still doing it so now the fun part is taking off the passenger valve cover.. Im 98 percent sure it the passenger side cause when i pull the connector the truck runs the same
