Kind of surprised there isn't a sticky for idle issues. Something like...
1. Verify no DTCs, fuel pressure, coolant level, strong battery (capacity ck), clean air filter, Ohms check ignition coil, ign source voltage & ground (zero resistance)
2.Verify plugs - AC IRIDIUM*; wires - Delco - OE*, cap & rotor - Delco*
*=recommended for reliability
