91 hatch oil buring/ intermitent stalling

ok yall i tried looking thru everything here and im at my wits end . i dotn know much about trouble shooting motors, electrical sure .. but anywho ...

i have a 91 hatch with a mpfi swap in it ...( intake, header, exhaust, cam gear nothign to crazy ) and the person i know who can fix this is being a lazy a$$ ... so i need some assistance .. i burn oil like a mad man , i step on the gas cloud behind me .. what should i look at it, check etc i honestly have no clue .. my car also will die when i come to a light , dont think its a vacuum leak i replaced all the hoses due to a vaccum leak so help please before this thing becomes my next bonfire LOL hahaha !!!!

hope everyone had a good new years !

Burning the oil is from shot piston rings or valve seals. Sounds like time for a rebuild or a swap.

i was afiradi you were gonna say that LOL ...im gonna try the valve seals first hoping that thats the issue
