I have a 1995 dodge stratus es 2.5L. About 6 weeks ago I replaced my crank sensor, before doing so I had the distributor cap off and plug wires off testing for a no start. Since getting it running again (crank sensor) it has a bad hesitation, the warmer it gets the worse it runs. I have three codes from the ignition 12, 51, 32. (My catalytic converter has been removed) When idling, in park, if I step on the gas heavily, it bogs down badly but won't die. Fuel pressure is about 30-35 psi. While driving if I give too much gas too fast, it hesitates, and I can hear and feel a knock under my left foot. If I feather the gas just right I can access all available power. What is my best course of action for self repair? I work at a GM dealership but answers are limited for a dodge! Please help me!

I am curious how you are reading those codes?
From the ignition? You mean key on/engine off?
Also, have you cleared the codes and did they all come back?
Also, how long has it not ran? More info is necessary.

Code 12 just says your battery was disconnected. Code 32 indicates that there's an EGR system failure; code 51 says the system is running lean. Were these codes present prior removal of your converter? If not, you may need to put the converter back on. If they were already there, then you might need an EGR valve.
