I am having idle issues with my s13 Sr. Once I start the car it will idle Normal for about 1 min or until the gas is touched. After either one of those it starts to hunt for idle. It revs high then drops. And leans out to 22.5:1 afr. I have boost leak tested it, changed the O2, maf, iacv, and the coolant temp sensor. The only thing that fixes the issue is when I unplug the coolant temp sensor sub harness. What am I missing?
