It's all Greek to me.
My recently acquired 01 2wd 4dr Blazer is difficult to start. But if you manage to keep it running until it warms up it will idle fine. No misfires. It's when you attempt to rev it up at all that it starts to sputter and stalls. Here is what the fuel trims were during normal operating temp at idle. Someone with more experience at deciphering these readings could perhaps make a suggestion on possible causes?
Thanks!

 

It may look like a vacuum leak, but the data You have posted are incomplete for an accurate troubleshooting.
Your car has two banks (1,2), while I don't see the data for bank no. 1, but just for a bank 2.

Please post the values for:
1+2 bank at idle long term/short term fuel trims
same with 1+2 bank at a higher rpm (let's say below the rpms where engine sputters) if possible

You may use Torque app. if You can't find the bank 1 in the current one.

 

Ah ok. I have Torque. Just haven't used it in a while. Will post up required data when I get back home Sunday. Thanks!
