93 olds 88 Ignition problems

I have a 1993 olds 88 royal with the standard 3.8 liter and im having some ignition problems

- I bought it from a older lady, in which was sitting under a tree for two years
- When i got it, it didnt run ( bad ignition modual ) in which i bought a a ignition modual / coils from the local junkyard
- Well it was still running rough however, my computer wasnt stating anything is wrong with it ( slow acceleration, rough ignition around 55 mph and poor fuel ecnomy 12- 14 mpg)
- that modual was short lived in which i bought a new one and installed
- still running rough
- bought a new 02 sensor slightly better not and dramatic increase however
- I blew a fitting and lost my coolant and overheated, since then ive been running off 4 cylinders (the lower coil isnt firing)
- nor is my computer stating anything
any ideas on what the problem is? thanks

Did you replace the wires?and if your coil isnt being signaled it also won't fire.Try cleaning the bottom of the ignition module and put a little never sneeze on it.

sorry to re-reply but does your engine light ever come on like when you first turn on your ignition key?

Could it be your computer. Have you unplugged the injectors one at a time to see if there is a change.
