One day i was driving and all of sudden it was like my car was in neutral it did not wanna go. Before this my car would shut off right after i start the car every once in awhile so i changed the o2 sensor, the TPS sensor transmission fluid and filter . now when I put my car in drive I have to hold down the gas for a while to get it to move then it drives fine and it goes in reverse no problems....everyone tells me that there's a lot of sensors I don't know which ones to replace.

You don't replace anything until you have diagnosed and confirm that the sensor is bad.

Above link explains how to check for trouble codes. For transmission codes, note the OD light blinking codes. OD OFF light should be turned off for this process.
