virtually no idle - won't stay lit

used to rev high when he started (weeks or months like that) it then it started dieing at idle and he had to keep it revved to make it stay lit - drove it for about a week like that, then it started getting hard to start (had previous starter problems as well, suspect bad flywheel)

he says it chugs a little but just won't stay lit, like not getting gas

don't know about exhaust flow

his receipt is for an idle air control valve and a throttle position sensor, previously the fuel pump was checked and a new filter installed

edit to let me toss in a thanks! here
