Dont know my beretta will start and run but if u hit the gas it will spit and spudder u cant rev it higher than 3 thousand rpm's just changed the plugs and wires and got the coil's and modgel tested and thay are both good

Run fuel injector cleaner through the engine.  If the injectors are clogged the car will hardly run.  Trust me I know, I had a beretta that had the same problem.  I took it to the dealership and when the machanic took it out for a test drive to see what the problem was he couldn't keep the car running without holding the gas to the floor.  Whe I asked him what he though the problem was he immediatly said the fuel injectors were clogged.  It comes from running cheap gas.  I was surprised to read in the owners manual that no less than 92 octan rated gas should be ran in the car.  He cleaned the injectors and the car ran fine. 

Runs but spits and sputtersaround 2000 rpms and then stalls

Check your fuel filter and make sure it not plugged up, make sure you reinstall exactly as it came off.
good luck
