Possible intake air (vacuum) fault, faulty fuel pump, Idle Air Control system faulty or emissions fault.

Run a bottle of fuel system cleaner in a full tank of gas.  
Chevron with Techron Complete Fuel System Cleaner is one that I have used with very positive results.

Lots of people also use SeaFoam.

If you run it through the fuel system the normal way, it will clean up everything from the fuel filter through the injectors/carbs, intake runners, intake valves, combustion chamber, piston crown, upper piston rings, and exhaust valve and port.

Once this is all cleaned out, you should note much better characteristics.

ok. major problem. everything got fixed and then my transmission, i guess, locked up. its in nuetral and wont go into any gear what so ever. clutch is still good and so is the fluid. is it possible that its just a piece that broke off in it and i just have to take it out. or is it something worse.
