no combustion from 1 and 2 cylinders

3 and 4 are both keeping the car running but 1 and 2 have spark but no combustion and is making the car miss very bad but it has very compression on all the cylinders i also do not have the o2 sensor plugged in

I assume there is no change in running condition when you pull off the plug wires on cyl. 1&2. If not, verify you are getting spark to those 2 cylinders. Then you can narrow it down to a fuel problem. After the car runs for a second, pull the plugs to see if they are wet. If they are, then you have fuel. If you have fuel, then spark, your problems lie mechanically in the pistons/valvetrain area.
