Cadillac Repair: combustion problem, fuel combustion, fuel consumption

Question
Dear Sir,
I have a problem with my Cadillac sts95 northstar, sometimes when I starts the car , a blast occurs in the engine and  I can see the smoke coming up. Also the car seems to be very slow and can t handle up slopes . My fuel consumption increases.
When I m driving the car I press hard on the fuel pedal to increase the speed of the car, and suddenly the car take it too fast and increases the speed. I feel smthn wrong in the fuel combustion. I changed the wires connected to the coils. Could it be the coils on the top of the engine?
I cleared the history codes and took the new ones:
P085 Current
P095 History
No IPC
NO ACP
R017 Current
R025 Current
R026 History
R051 History
R052 History
T027 Current
S036 History
S038 Current
S044 History
S060 History

Please advise..
