what to replace to get smooth engine?

what type of things should i replace to get my engine running smooth again?....does the 95 sunfire have a pollen filter?.....also has anynoe had problems with their lights behind the heat control?..my lights seem to not work, check fuses, they are fine.??...PLS HELP ME>>????

Replace fuel filter, plugs and wires, air filter, other routine maitenance, check injectors for leakage, check head gasket, check coil packs for cracks. No the 95 sunfire does not to my knowledge have a pollen filter. Check the bulbs to see if they are burnt out, or the connectors.
