As I am driving it will suddenly flash P01 or P00 then start showing readings as .XX. The dial will stay correct but the digital read gets weird. I tried to video it but it is totally random to do this.

 

Sounds like you have a loose power connection.

 

no mine does not.

something sounds loose/off.

 

Why would it read out with a decimal? I would think if there were a loose connection it would be blank.

 

when i start my car, it first says

UGO

POO

then starts to read

is this what u are talking about?

 

Mine does this, haven't looked into it.

I think it's switching between UEGO/Lamda, no?

 

I would think if it reads fine then maybe it is a loose connection that is getting jarred when going over bumps and resetting itself as a result?

not sure, just a guess.

one thing is for sure, mine does not do that.

 

Sorry back on topic, it seems like it changes to a decimal when it peaks past its reading capabilities(too rich/lean).

 

That's what I was thinking but why would it switch on its own?

 

no mine don't do that......something is loose in there.

 

loose power connection....

 

you go poo!!
thats tooo funny!!!!

Check the connection..
