- I took the throttle bodies off, all hoses look good.
- Bench tested the ISCV and SAV, both OK.
- Reassembled and it ran, very fast idle.
- Connected up a pair of gauges to the throttle bodies and rebalanced them, it ran better.
- Adjusted the Throttle/Idle screw stop as I noticed that the butterflies were not fully closing when I had it on the bench.
Video attached of how it current runs, sometimes it will run ok for a minute, then end up as in the video, eventually it will stop. Also seems very hot very quickly. Fan turns on though.
