I'm new here so try not to tear me apart but I'm a rotary engine enthusiast and I need to learn but I honestly have no idea as to where to start. I recently bought an 88 Fx3s N/A and I knew it had problems. When I start it, it idles at 4500 and then down to 3000 and I have to constantly feed it gas to keep it running. Any advice on where to look would be greatly appreciated

 

Replace all vacuum lines than start again
