Default help please!!!

Hey guys,
Im new to this sight as well as ls engines and in a bit of a bind
After my rebuild... Im down to 2 problems at the moment...


1. My car is running rich as hell, and cant figure out why? Ive replaced both o2
Sensors, new plugs, wires, cleaned MAF sensor still nothing... It idles great besides
The strong gas smell, but when i drive or go WOT, it hesitates, bucks and pulses..

2. The tranny... I cant figure out what its doing either... I replaced the pilot bearing
During rebuild and it drove great for the first 100 miles of break in. But now
When i drive it, i suddenly loose pressure in my clutch and it grabs its about 2-3 inches
From the floorboard and wont go into gear.. but turned off or idling it shifts fine ive bled it twice to no prevail... Took it to a mechanic, and after
1 week (and alot of money) said they fixed it.. made it to blocks from shop then had to
Putt putt back to shop...

Mt question is.. what could cause my engine to be running crappy when
everythings new (within 100 miles of usage) and what could be causing my
Tranny to be acting bipolar lol... Could it be my slave or master going out?

What about ECM codes? That should direct you to the problem and if you don't have an OBII you can go to Auto Zone and they will tell you what the diagnostic trouble code is.
