71 = cylinder #1 misfire
74 = cylinder #4 misfire
80 = EGR low flow rate

I try that the first time and it work for a few days but it came on again.. I can hear like a vacuum leak somewhere by cylinder 1 right by the intake manifold, but can't find the leak. have any idea which hose I can check??

Could be your intake manifold gasket or even the fuel injector o-rings, also if the light flashes, it means catalyst damaging misfires, in other words, it's destroying your catalytic converter.
