Hey yall, first time here and first time owner of a 1984 Rx-7 FB GSL-SE 13B. I've been having trouble with starting it up recently with it shooting up to 4000rpm and then dying immediately unless I pump the throttle to keep it at 4000rm. It was running just fine before hand but leading up to my problems my car would start up fine then die a few moments later but restarting it would work just fine.
