1998 cylinder misfire
 

Can you guys help me out. This is driving me nuts. About 2 months ago, my car started "bucking". So i changed my spark plugs. Start it up again, same problem. Now fault of money problems, wait a bit. Just changed my wires, distributor cap and rotor on friday may 20th. Start it up again seems less worse, able to drive around, still some small bucking. Figured the car sat for 2 months, maybe gas isn't all that good so not burning right. Lone behold star my car on sunday morning and check engine goes back on. Again, CYLINDER 2 MISFIRE. I know my way around under the hood but this problem has kinda got me agaisnt the wall. I really don't know what now?????? HELP PLEASE.
