no pick up

I have a 90 3.1 5 speed cavalier it runs great at higher speeds,the problem is getting it there. If you baby it through the gears it will do fine with no miss.
If you have to pull out quickly it feels like it flooding out. The car ran fine until the plenum gasket and pcv valve was changed. Thanks for any help.
