my 93 wrx does not always run on boost right it holds back but the turbo still boosts up feels like your running with the brakes on, it also runs very rich all the time

Sounds like an air leak to me

but it only does it evry so often, it will do it constantly for half a day or so then go like a train for the next few days but it always runs rich
