RE: o2 sensor location
Hi,yes it is normal to have 4 O2 sensors. Two heated oxygen sensors and two monitor. There is one before, called the upstream, and one after the catalyst, called the downstream. On your specific truck, if I remember well you have three. One because each catalyst on each side of the engine (this part is called a Y-pipe. After the y-pipe there is twoin-line catalysts and there is one monitor between these two.
But, before replacing part for no reason, I suggest that you have, at least, your code scanned if you don't want to pay for the whole diagnoctic. The we will be able to pinpoint your problem.
