Ok thank you. If it is the fuel pump is still under warranty.

Yup all the symptoms , thats how i got my yukon so cheap, the guys mechanic did a full tune up with new o2's and fuel pump. So the guy just wanted what he had into parts back. Took me 10 mins to diagnose..Fuel pressure droped 30psi in one second. I popped the TB off and #2 & #4 had cracked lines flooding the system.. causing the front o2's to command a super lean with fue l delivery and hella retard timing condition.

Its not a bad job at all, took me about an hour each each way. Now it runs like a top!

Quick question could it be a clogged catylic converter.
