Well I had recently bought my supra and when you turned it on it idled at 2500 rpms, turned out the throttle cable had been broken so I replaced it and now it idles at 1500. How can I get it to set at a comfortable idle where it doesn't kill my gas, I'm thinking 750rpm. And the winning sound I usually always hear in first gear when letting my foot off the clutch and when slowing down and it's not my turbo. Thanks for the help!!!!!
