I have a 2005 STX Neon that has ran great up until now. It runs really rough
it has new wires and I have cleaned the throttle body a number of times. I don't have a ton of cash to try this and that by replacing a bunch of parts with the hope of getting it fixed.........so that's why I'm here!

 

Were spark plugs changed also?

 

No just cleaned them up some they looked great, but that was my next step thanks for the reply.
