i bought this prelude for 300 bucks knowing that it had a problem, the guy said it needed new plugs and wires but that is not the case (i dont think)
here is what i have done and came up with so far

car starts right up but it runs really rough like its on 2 or three cylinders and sometimes stalls.
did a compression test to see if i had burned valves and everything came out well there
I took out plugs, they were all extremely black so i replaced them just to make sure,the car ran good for about 20 min then started acting up again, i took the new plugs out and they were pitch black yet again.
i thought maybe the wires were bad so i changed them out today and i still got the same shitty idle and troubles.
i took out each plug individually and placed them on the block then cranked the engine over to see if they sparked and they all did.

It seemed to me like everything was working right so now im stuck
then only thing i noticed was cylinder 2 plug was not black like it was not burnin but it sparked fine and passed the compression test.

PLEASE HELP ME OUT
sorry if this seems kind of confusing

 

has the fuel filter been replaced?

 

not since i have owned it could that be a factor?
cause it feels like only 1 or 2 cylinder are not firing plus it smells real bad like gas and sometimes it backfires but maybe thats cause the exhaust ends at the cat

 

any other input, this needs to be running befor we get another snow
