I misread though you said pull the sensor not unplug

 

That's what you get for trying to read that teeny tiny print on your phone. You know, as you get older, that's gonna play hell with your vision.

Sorry, couldn't resist.

 

On the battery drain part you should check your iod fuse. Think its under the hood. Thats the ignition off drain. May have popped. Install any lights, radio, anything electrical on the truck lately?

 

Well as soon as a company provides internet for me I'll use my 8yr old desktop instead not my fault no finish wants to spend about $150,000 just to bring me internet, selfish people these days

 

I know. Its just awful. Comast is about two blocks from me, (less than a mile) but, they won't extend out here either.

 

I tried satellite but it didn't workout to well plus had a cap on how much data I could use

 

Thank you. I appreciate it. I'll give that a try.

I replaced the downstream sensor and had a new cat put on less than two thousand miles ago. That said, I suspected that the cat they installed was too small and not the correct one.

 

Thank you. I'll check that. No, I haven't installed anything new, but I did have several things unplugged when I installed a heater core and evaporator core. I also installed a new clock spring at the same time. The battery drain problem started after I did that.

 

Turns out the IOD fuse in in the fuse block on the side of my dash. I finally figured out how to get it out, checked it and it's not blown.

Thanks again for the tip. I had no idea about it and will remember it for future issues.
