92 MTX Misfire

[93SHO24V]

OKay so the car had a slight misfire earlier today so I took the intake manifold off and the lower gaskets were pretty much shot but I had to re-use them because I have no money to go buy new ones, I took the spark plugs out cleaned them up and put it all back together. Now the car runs like Shit and it ****** me off I know I did everything correctly and didnt do anything else what else could this be? I ran codes and it gave me a front o2 sensor not switching, something about pin #10 shows low voltage, and a couple other things in which I cant remember.

By running like sh*t, what do you mean? Is the misfire worse now, or something else? When's the last time you changed the plugs? What kind of wires do you have?

A spark misfire without an electrically-related EEC code points to the plugs and/or the plug wires.
