jumping?

So I recently had a squealing/ chirping issue and replaced the belt which calmed it down a bit but it still occurs every once in a while. I won't be able to look into it until I get home from school.. But while driving on the interstate and cruising for a while, the car started lurching randomly. It would just make am odd jump and then keep going.. Any ideas? Could it be a pulley that I still need to replace?

Does this happen while the car is accelerating? Or at constant speed?

I replaced the plugs and wires less than 4k miles ago... They've been running fine since and it only happens occasionally.. Could it still be a plug?

Mine did what you described when I had a cracked plug. But mine did it during acceleration too

Could it have cracked from just running to long and getting warm?

That's a possibility. Mine was cracked while putting headers on though

I'm just wondering if it has something to do with one of the pulleys because I almost certain one of them needs replacing I just never can pinpoint which one

Check the coil pack. That may very well be it, if not other things that may cause this is bad/dirty IAC valve or a leak on one of the vacuum hoses, I do not think a bad pulley would cause this, it sounds more like a spark problem, which may be caused by the air intake of the engine, or the ignition (coil, spark plugs, wires), it can also be caused by a bad fuel filter or clogged cats. That's about all that can cause this lurching problem you speak of.
