Derwood00. 2000 Blazer 4x4

Hello I have a 2000 Blazer 4x4 LS. With a 4.3
She has a miss at idle. I have changed the spider injectors, the Idle Air Control Vale, Throttle Position Sensor, Fuel Pump, Spark Plugs and Wires, Distributer Cap, and Rotor, Have cleaned the MAF as well. It still has a miss at idle. Any clue or suggestions?

Welcome

Does your engine have an EGR valve? If so, You may want to check your EGR valve to see if its sticking open slightly.
