16 fuel injector system. defective circuit or unplugged / defective fuel injector.
start your car, when its warmed up unplug each injector one at a time. Each time you inplug the wires from the injector the idle of your car should drop (you can hear it). if it doesnt than that is the one that is messed up. what i did was i took out the injector cleaned it and pressed on the little thing at the end where it sprays the fuel ( i dont know if thats good..) i reset my ecu and the problem was gone. if that doesnt work than i guess you should get new ones or something.... I hope that helped, goodluck!

I dont suggest disconecting the fuel injector while its running. The proper way is to use a dso to test the injector.
