P0131 Question
Hello All,
I am looking at purchasing a T/A WS6 on Tuesday. I do know that the it has popped the P0131 message around 4 times over the last 6 months. Generally this happens after the car has been sitting for a will and goes away once warmed up, so says the owner.
My Experience with this Error code on the V6 Firebirds is as follows:
1. EGR
2. MAF
3. O2 sensor
4. After Market Muffler
How do these items translate to the LS1?

Later model Trans Ams - such as '01 and '02 are not equipped with an EGR valve. Let us know what you find.

Thanks for the Info Pajeff02. I will have to looking into this more as I have found the Duralast EGR1103 fitting the 01 and 02's.

WhamHammer, I will look into the exhaust as well. I know that it has at least an after Market Muffler, maybe more.

WOW, I had no clue of this, and now it brings up more questions then answers. So most 01/02 Birds, got the LS6 intake, which is why there is no EGR. There are Many posts out there suggesting that the some vehicles got the LS6 block too. Any clue how to determine this? That is what I am looking up now.
EDIT - Found the Info. Thanks again.Last edited by MikadoWu; 07-17-2016 at 08:52 AM.

There is a casting number on the back of the block just beneath the driver side head. You need a mirror and a flashlight to see it.
