Two Questions for yas about a dodge neon!?

k first one, i got a 97 dodge neon and i wana know where to get the r/t stripes at? and the other question is while im driving i notice its bucking a lil bit.. not alot.. but once in awihle it does and it dont matter what rpm im at.. for about an hour it wont do it but then like in 5 mins it starts happening again. it only does it for like 15 seconds and it stops but starts again, i checked everything like the plugs, wires, coil, all that stuff and its not even throwing any codes at all.. gas miliage isnt droping either.. ooo and it really happends when im on the gas floored, if i were to floor it and it gets up past 5500 rpm it gets reallly bad and it bucks really tough. it has a 2.0L dohc and its a stick.
