Hello folks I’m new to this site , I just had the intake off my 98 GMC 1500 as the inside of it had 1/8 inch of gunk in it , i got it cleaned at an industrial cleaning place , come back beautiful , I eliminated the EGR with a plate but left it plugged in , after reassembly and getting the timing dialed it’s running like it should but for some reason the transmission won’t kick down when I step on , I douible church myself as far as plugs and shit it can’t figure out why it won’t , it was before the work ,
