Runs poor all the time or only bad at idle?
Probably an air leak with that description of maf disconnected . Try pulling the brake booster hose and plugging the hole in the intake then see how it goes. That would point you to a blown booster giving the motor extra air from what the maf reported to the ECM. It is sort of dumb. But without fuel trim and other data its is a little hard.
It is ok to drive with AMM disconnected for 1 trip since it then just looks at manifold pressure / rpm .. etc.
