B&M Converter is bad

big difference on how a car will idle between initial timing and total timing...

so the converter works fine except the engine dies at idle in gear.?

The cars idle is set at 1200. Once you put it in gear it drops to about 500 and runs rough. It wants to just take off. I can't even foot brake the car and get it to spin the tires because I can't get the rpms up. The car just wants to take off and go.
