Does anyone know what code 13 means on a Pr4. Also i have a crx with a b18a1 swap and when i use the crx si single cam computer my idle is fine but with the Pr4 it idles crazy and it breathes. It like goes up to 2000k and back down as if it had a vacuum leak (which it does not) this is what i mean by breathing. Can anyone help? Thanks in advance
