sensors, MAF, fuel filter, spark plugs and coil packs. The fuel pressure is 25 running.Any

I do not want to throw money at this. Fuel pump, cat converter, any other answers?

Fuel pump would no cause the issues you describe. Dirty or clogged fuel injectors would. Using anything but Premium gasoline "gums" the injectors up very quickly, within a tank or two. Before changing out any more parts it would be worth it to use a high quality fuel system treatment. Lucas makes a high strength version that works well and BG 44K, while the most expensive out there, is very effective.
