Any ideas if this could be my O2 sensor?
Check for intake manifold for vacuum leaks, use a can of spray carb cleaner and spray around the top of the engine, if you hit a leak the engine idle will change, P0302 is a miss in #2 cylinder (cylinder power output low, lean cylinder due to poss vacuum leak and other issues.). once again an O2 will not cuase a mis-fire.
This involves the front oxygen sensor on bank 1. This code indicates that the heated oxygen sensor reading is too high.
The simplest thing to do is to reset the code and see if it comes back.
If the code comes back, the problem is more than likely the front bank1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:

I reset the codes it came back only as a P0302. If the P0132 comes back any ideas on where to start looking for problems? O2's are only 2 years old. The longer i run the truck the more codes i get along wih the P0300 and P0171.
Tried the carb cleaner on the intake and had no idle change at all. Soaked it real good. cleared all the codes again. let it idle and P0302 came up. No other codes so far. Got me goin crazy... if it was my 66 dodge I could fix it!
Sorry.... not real sure how to rate these things. I'm new to the site. Still workin on the problem took out the dist and plugs and wires. Gonna start there first.
this would not be an O2 problem 100% sure of that, The O2 is just reporting what it see's going on with fuel ratio, concentrate on the miss firing which is a very lean mixture or an ignition problem.
