I have single turbo T04S 3rd gen rx7 with pfc. The car will stall when I am driving sometimes, i just feel that there is no fuel and the rpm's just die, usually from 3K rpm. Sometimes at idle it dies too. Happens randomly. Very hard to start up after it dies. Sometimes have to wait 5 min. I tried adjusting the fuel at idle but that didn't seem to help. Any ideas?
