[V8] MPG - now stalling

[Jason Wilkerson]

Ok guys,  
   This is what has happened so far. (some of it is a re-cap) 
1. When I bought the car, before I even had driven it I replaced the o2s
2. When I start driving the car I notice really bad gas milage (14mpg
-used to 18.5mpg on my last v8 with more miles.
3. Check codes, get 2341 - out of range - causes could be: leaks in      
intake/exhaust, high or low fuel pressure, Ignition failure, bad o2s
4. Check o2s for output - seems to be functioning properly.
5. Car starts dieing intermittantly, expecially at a stop, then stumbling
horribly on the throttle - figure it is low ATF - find out later it isn't.
6. Change X-pipe with another o2s in it due to a patch job on the original
x-pipe (thinking this is the cause?), find that this o2s is bad and is
putting out no signal at all - this throws a code 2342 - disconnected o2s
- car runs great with no stalling but mpg stay around 13 or so.
7. Change out old o2s with the new one I had bought - car immedieatly dies
at idle - throws the 2341 code again.
8. Where do I go from here?

I really think that I need the time to pull apart the intake to look for a
vaccum leak, also I need to test fuel pressure.  I have changed the FPR
and MAF with known good units.  If any one has any ideas let me know -
expecially vaccum leaks to look for - I can't afford the gas anymore, and
besides it bugs me to know that the car isn't right!

        Thanks,
             Jason
