i'm a noob to rotarys and someone wants to trade me a 91 rx7 convertible with a turbo 13b for my 95 dx coupe with a gsr.
the car idles up and down, he doesn't know what's wrong with it. he says he thinks it's a vacuum leak. he showed me what he called a "boost selenoid" on the side of the intake manifold that he just changed the gasket on. he said those are 1000 bucks new. to me it looks like a idle air control valve but he assure me it was not. could this be the problem or do you guys think it's something vacuum related? any information would be helpfull
