Need some help....

Ok I dont know of anything else to check...

This is the list of NEW parts

-Opti
-MAF
-MAP
-EVAP SLND
-Changed the burn plug wires
- O2s
-New module underneath coil pack (delteq)
-sanded all the grounds
-New wiring harness for the engine (only wire that still shows bare copper and frayed is the oil level sensor)
-Checked plugs
-Checked wires

It misses terribly

then it throws a code then runs really boggy....I really need help

I cannot figure this out....

Idk, my car is a 96 and it has a sensor from the timeing cover down by the crankshaft. I guess I havent looked too hard at a 95 to really tell.

95= no crank sensor but, the crank sensor on 96-97 does nothing as far engine control. It is just there more mis-fire detection.
