Volvo 940 1993 estate

Hi all.
I am new here and from Norway and have a technical question.
I have had some trouble with the engine(220k km). under load it does not pull as it did especially uphill. It sounds like it don't ignite on a cylinder. I changed all the ignition parts (distributer lid, rotor, ignition cables, coil and sparkplugs).
Then it got hunting idle but that dissapearedafter a drive, but the loose of power under loa still exists.
Fuel filter is about 50k km the same is the fuel pumps.
Do please you have any possible suggestions about what it can be??

ADDITIONAL SYMPTOMS.

When driving uphill with load on the engine feels like somebody tries to hold it back and it can loose power and it comes back.
Another thing that hasoccured is that having slight throttle on downhill and suddenly have no throttle the engine suddenly and much stronger "breakes" than before when it was not that suddenly. So with suddenly giving a lttle throttle and then no throttle the car "stumbles" which means it is not comfortable
Hope this gives more info

Fuel Pump Relay?
Clogged/Collapsed Catalytic Converter?
Dirty Throttle Body?

What codes is it throwing?

Good luck.

Mine was sluggish on hills...
I had new distributor Cap,Rotor arm,Air filter..

mines like a new car again...(it wouldn't rev over 4000rpm under load before)
