Help diagnosing CEL codes
 

I was driving to the gym today and noticed that my CEL popped up. Terrific! Once I stopped, I checked the codes with my dashscanner and got these 4:

P1000
P2195
P2196
U1900

Anyone?

All 4? :| Google it.

Yeah, it seems like 2 of them are non-issues and the other 2 are maybe running lean/rich. Just wanted to see if anyone has had any experience with them

Did you get a new tune recently? Sounds like it might be that.

I had to remove the CAI & tune for inspection over a month ago and then reinstalled them. But I've been running the same Bama 93 tune for months and months. I'm going take the highway tomorrow on the way to school to hopefully go through a drive cycle. Couldn't hurt right? If not, I'll give AM a call

For what it's worth, I also checked my CAI this afternoon to make sure everything's ok and tightened all the clamps. Nothing stood out to me

So the one that's throwing a CEL is P2196- o2 sensor signal biased/stuck rich (b1,s1)

Right but 2195 is lack of switching system lean, so most likely it's in the tune or the PCM is having a brain fart from the return to stock and the reboot. I'ld clear the codes. Reload the tune properly and take for a drive and see what happens.

That's what Im going to do. I cleared the code and am going to reload the tune when I get home. It's running strong otherwise
