Ok I drove through a big muddy area yesterday and hit a few puddles, nothing a disco can't handle right?

A bit afterwards I felt the car shudder at idle without RPM gauge fluctuating
Got home a few miles away and all seemed well. I drove to work this morning and found the service engine soon light on.
Checked codes after work at autozone I got

P0152 - o2 sensor?

then P0301 and P0305

Anything to do with the puddle? What should I do?
Drives fine like nothing is wrong except with a random shudder here and there at idle

 

What color are your plug wires, if grey, they are junk and and would cause the 2 mis-fires. You need 8 mm silicone wire that won't leak when wet throwing codes. as for the 152 code, bank 2 sensor one is gone and you should replace both front's to get your air/fuel ration equal on both banks.

 

I have yellow ones they were recently replaced. During a top end rebuild for headgasket
I forget where and what they are called. Kings something? I believe they were 8mm

Is bank 2 on the passenger side?
Is it at the bottom?

If it dries out should it be fine?

 

Only time will tell.

 

Looks like you got misfire codes.
You can plug codes into this site:

http://enginecodemaster.com

It has most of the codes from the RAVE in it by now.

 

I had issues with getting some O2 codes, and I replaced them one by one only to have the next one go. I replaced them all and haven't had an issue since. Best to do em in pairs at least IMO
