codes p102 and p1125 help

[4x4k30]

ok I have checked the codes on my 79 6.0 . they are p102 maf and p1125 throttle body. it still will not run over 5 mins. with the maf sensor hooked up if I unhook it it stays running .also the p1125 has to do with the t/b and pedal somehow.. my pedal and tac module and ecm are not the orginal parts to the engine harness it runs ok without the maf hooked up but it acts like its flooding when I first cold start it and after a few mins. it idles smooth
