LT1 IACV

So I went through a bunch of different tests. Started car initially without flashing and got it to fire up, idle and run. Running symptoms deteriorated and idle stuck around 1700 RPM. pulled Ide Air Control Valve out and tried to clean it. Apparently the plastic mechanism inside has broken in some way or another . Once I get the idle down it might act properly. So the water something light is on but it acts kind of flickery. And it says I am low on oil, added oil and that went off after repairing a few wires. Also after repairing about 5 wires total there is no check engine light until it runs approximately 10 seconds. still idles 1700. gotta buy an IACV.
