1994 Ford Probe idles a little low and sputters on accelera

Hi there, So this all started about a month after I bought my probe, I was dinking around under the hood and pulled out the pcv valve and the car died, so I put it back, and ever since then whenever I stepped on the gas from a stop it would sputter until it shifted out of 1st gear, I asked a mechanic I knew and he said maybe a tune up so I replaced the plugs and wires and that made it run 10 times worse, it would sputter off the line bad and around 40 mph, but over 60 it was fine. Sometimes I would go to take off and it would rev up to like 6000 rpms and then take off and shift hard. Since it ran better before the new plugs I put the old ones(which were fine) back in and it helped some. I have replaced the pcv valve, the plugs wires cleaned the points on the cap cleaned the throttle body and the maf sensor, and taped up some cracks on the rubber piece that goes from the maf to the T.B I am stumped and really annoyed Please help. Oh and no check engine light and it is fine while cold and gets worse the warmer it gets. Thanks for your help!
