Default suddenly running bad.

Hey guys so my 95 has suddenly started running really badly. Im thinking its the cold because it ran fine when it wasnt all cold and snowy. Anyone have any thoughts on how to make it run normal in cold *** weather?

Most recent was a fuel filter and fuel system cleaning. Im hoping a tune up will help out. Havent replaced plugs or wires since i bought it 2 weeks ago

Can some define "running badly"? There's absolutely no information here to work off of.

Are you throwing and CELs? Gas mileage bad? Idle issues? What?

Running badly as in dying after starting and driving with a bogged down feeling. I can literally feel my power come back once im up to speed.

I dont see how a new fuel filter could make a car run worse. I know who did it and know they did it right 100%

what it sounds like to me, is your filter was clogged before you changed it causing your fuel pressure to be lower... ok so now you changed your filter allowing your fuel pressure to come back up where its supposed to be but now your running rich/flooding the car..... to me it sounds like either your fuel pressure regulator is bad or your injectors are bad... the reason you didnt know that before was because the clogged filter lowered the pressure enough for the car to run right!! im not saying its for sure 100 percent your problem but ive seen it before and might give you a place to start looking!

what you could also do to kind of confirm your running rich is to pull the plugs out and see what color they are, and see if they are wet or dry...

I pulled the plug boots out 3 days ago just to see if they are intact and the were wet with some sort of liquid but i did spray a plug cleaner in there like the day i bought it.

well if the plug boots are wet its usually oil coming from the seals that are supposed to keep the oil from getting into the plug area!! but in order to see wether its rich or not you have to actually remove the plugs from the head and look at the end that goes into the engine

Mileage on the car/motor? Also you didn't answer marks question, does the car have a CEL(check engine light)?

Inspect the spark plugs, wires, distributor cap/rotor, and coil. Replace if necessary and move from there.
