I've just installed the fuel injection kit on my 79 MGB, and really happy with it, but the idle is around 1400 rpm. I can't locate any vacuum leaks. Where do I look, and how? The car also runs on the hot side, very close to the red zone. Is this ok? Finally, it doesn't have much power, but I've never driven an MGB before, and it didn't run when I bought it, so I don't have any experience for comparison. Thanks.
