Poor idle how do i change the fuel filter

Possible catalytic converters or mufflers are restricted .

Sorry guys i was late with my feedback... So here it goes.. I have no check engine light.... Currently running the stock tune as well.. The car has no tps, pcv or egr valve.. It is all controlled by the electronic throttle body which i recently cleaned but didnt help with my problem. I ordered a new fuel pump as well, just didnt get the chance to install it yet. Cant change the fuel filter as it is builtin within the pump. However, shouldnt the fuel pump or fuel filter cause engine stalling, bucking and hesitation? I doubted the fuel pump could be causing this since the problem only occurs at idle. By the way, there is no missing on any of the cylinders.

run fault codes and replace faulty sensors/ servos.

change fuel filter & change air cleaner filter, sounds like fuel and air problem RayC

check fuel filter. it is starving for fuel. unless the fuel pump is bad. check filter first, then go from there. symtoms of a bad coolant sensor--poor cold idle, stalling, rich mixture retarded timing, slow idle speed, cold hesitation or stumble, poor fuel milage.

CHANGE FUEL FILTER.HAVE FUEL PRESSURE CHECK AND HAVE THE IGNITION TIMING CHECK.TIMING COULD BE OFF A LITTLE.HAVE IDLE SPEED CHECK ALSO.

symtoms of a bad coolant sensor: poor car idle, rich mixture, retarded timing, slow idle speed, cold hesitation or stumble, poor fuel milage, check and make sure air filter is clean. and check plugs and wires if need be,

I think some air going into fuel system.Need to put some compressed air in fuel tank and check for leak.

check transmission fluid.change fuel filter and air filter.try changing up on where you buy gas .because bad gas causes problems.

change air filter.and fuel filter. replace plugs and wires.check tires air pressure.
