Most newer fuel injected vehicles have a idle control valve or idle speed motor or a variation of one. A idle speed motor controls the idle speed but when they are defective, they can allow a lean mixture which can cause a very rough idle. WRONG! A malfunctioning iac will NOT effect your fuel mixture. Your misfire problem is likely one of five things. Bad injector, bad spark plug, bad spark plug wire, bad egr, or bad egr control valve. If the problem is ignition related it usually gets worse as engine load is increased. A dirty injector can cause issues across the load range. A bad egr or egr control valve will be worse at low engine loads. The control valve is strapped on the side of the intake tube from the airfilter box to the throttle body. Find the hose going from that to the egr valve itself and unhook it. If the idle improves, you have a bad egr control valve. If idle does not improve, chech the other items (egr valve, plugs, wires, injectors).
