Start by pulling codes. You should stop driving it until you get this sorted out.
i dont drive it right now due to the problems. i was driving one day and it started missing and breakin up so i took it to my house and its been sitting ever since. i tried putting it on a diagnostics machine that my dad has and the only thing that keeps popping up is MAP sensor i tried changing it but still didnt work. do you have any other ideas or suggestions?

Have you kept up with regular maintenance? On this diagnostic machine, can you check out the ingition module? After you pull the plugs, do any of them look bad, burn't or damaged? Can you post some pics of your plugs and label which cylinders they are from?

I don't know what that "diagnostic machine" does. This is not a new car you are dealing with, so keep it simple. Just pull the trouble codes from it, which can be done with a paper clip if you have to. That way you know what numbers are coming up.
Otherwise, I'd start by checking the spark plug wires and plugs.

i will post some pics of the plugs today. i changed the plugs once and wires too. cap and rotor was replaced didnt make a change. what the diagnostics machine does is it plugs in to the computer and tells me if there are any sensors or anything going wrong. it also tells me if its running lean or rich and it pulls up codes to let me know how my car is doing. i have kept up on regular maintenance plugs wires oil change every 2500 miles i take really good care of it. air filter and fuel filter was replaced when i got the car. any chance it could be a bad body ground or a bad connection somewhere???
thanks man... so your from ohio?

It could be bad grounding, but it doesn't sound like it. It seems to be like a bad TPS, honestly. You don't have bad gas in there, do you?

Yeah, I'm a transplant...
Outside of all that inspection and double checking; JoshMcMadMac has a good point. Have you checked your Throttle Position Sensor to see if the voltage is in range?
