My 100Q has no power again,,, big cow..

[Denis]

Since i have this 100Q 1989 is not powerful at all, nothing like my 90 1988, same 2.3 same CIS-3.....

2 weeks ago i notice the car runs better when i touch the little gray module on the fuel distributor..... then i clean the module plug and changed the connector.

So after that the car never run as powerful than before.
I was very happy, i can now pull a big trailer fiiled hard wood, up hill with no problem, i can even accelerat......

BUT the fun has gone 2 days ago......

The car is hard to start ,again,,, as before it seems no compression or not very much effort to start,,, like an old man...
The engine is oscilate between 1000-1200 even i removed the idle stab valve (was much worst with that valve).
The engine stop oscilate when i unplug the gray module but i dont have power..

When i accelerat i must let the engine take his breath before i can push more on the accelerator,, i f i even try more, the engine slow down like hhe has not enought gaz and to much air.....

I lett the engine take his breath , then i can push more a little again ,,,,, then again,,, and so on until i reach the speed i want.
Now i cant pull a trailer.... the car is like an old tired man .

So now why i dont have power on the car ? why is so lazzy ? 
It ran 2 weeks very good , powerful,,, then again very lazzy. I tought the plug was oxidated again, i cleaned it again  but nothing changed.

Any help is welcome.

thanks all
