My car idols fine but when you put it in gear or turn the A/C on it starts missing. When you try to drive off it cuts out until you get going and then it will not miss a lick until you lug it in overdrive.I have changed plugs, plug wires, coil packs and the crank sensor.I ran it up to 6500 rpms before it changed and it ran fine.
RepairPal Certified shops can diagnose and repair your 2002 Kia Spectra. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
In many circumstances like this I would typically suspect the secondary ignition components: such as ignition wires leaking voltage causing a cylinder miss. Under load designates a drop in ignition signals. You may have a defective component ex: a cracked plug.....if the ignition is good I'd check for a lean or restricted injector.
