O2 Sensor taking a dump?
I was driving today on the freeway and the car just instantly started running like crap. It instantly lost power, became sluggish, and my wideband went straight to "very lean". I pulled over and poked around and couldnt see anything staring me in the face.
I pulled the codes and I recieved a P0152 C, H "Heated o2 Circuit High Voltage Bank 2 Sensor 1" Would losing that O2 make the car run like that? I initially thought I might have a fuel issue but my FP gauge never dipped, stayed at 60 the entire time.
I started the car and it ran fine for about 20 miles and then started acting up again. It seems to be intermittent.
Any ideas?

I drove the car again, I cleared all codes and drove it for around 20 minutes. The car is having the same issue. It sounds like I have a slight exhaust leak, that might be one issue. Also, it seems like the more rpm's I turn the better the car runs. If I'm just driving at a steady pace it'll go lean on the WB and start chugging along, I can ease into the throttle and the WB goes back to normal and the car runs fine.
After the drive no codes were present.

Today I had the same thing occur. I checked the codes and now I have 0135, 0152, and 1154 all at the pcm.
I pm'd Bill Curlee and he suggested that I check my ignition switch. I checked all the fuses that work with the key on and they all had 12.2-12.3 volts going to them.
Anyone have a guess?
