Start but not idle
So I have a 1989 rx7 turbo swapped and when I turn it over it'll start up and die unless I give it gas. Just got the AFM all hooked up. Ideas?

A vacuum leak which is large will cause an engine to die immediately after starting. It could also result from having the fuel lines mixed up (JDM engines have their fuel lines reversed relative to their USDM counterparts). Could also be caused by a restriction in the fuel line, including the primary fuel injectors.

At one point the throttle cable was too tight so it would kick up to 4,000 RPMS and keep climbing until I shut it off. I loosened it and now it does this. Would the issues you mentioned still be in play?

I bought it from a local guy who just had it rebuilt and he said he didn't really wanna be in the car scene anymore. I believe it's JDM by the what the intercooler says. Intercooled turbo rotary or something of the sort. And what would you advise for checking for vacuum leaks?

When I sit there and rev it or hold gas it dies still. Thoughts? I'm really struggling
