I can play with the idle screw and kill it and open it up and somehow it will still find a way to idle at 1500.
It will creep up but eventually it idles at that speed.
Any ideas? Im guessing the car is now in open loop.
Car ran and drove great, then I did a hard launch and its been idling high.

check that small hose that connets the ISV to the intake manifold ,that one cracked on mine once. and i got high idle due to that
i've never seen 1500rpm out of a small vacuum hose break before, it has to be bigger then 3.5mm inner dia for that
I watched a mechanic do this recently. Get a vac gun (should be a free rental or max $30) and plug it into the ends of the vac lines in the bay. Draw a vac and listen for the hiss. You might have to pump pretty fast. I would say you have a blown off line. Good luck.
Edit: Quick tip, the only line that really matters for your idle that much is the ECU line. That, and the idle screw.
