is the motor a stock rebuild? whats the timing set at with the spout connector removed? have you checked the fuel pressure at the rail? double check the plug wire firing order. I would also check for vacum leaks.

something isnt right if your getting the motor up to temp, pulling spout connector and setting the timeing to 20* btdc.

I have mine at 12* btdc with spout connector removed, msd coil and plugs gapped to
.55
the 88/93 timing procedures are the same.
code 33 could be the sensor on top of the egr or bad vacum to the egr or the egr is bad period. I just got my first code reader and so far its worked as should. prior i used paperclip method.
