ok then scan for codes and check fuel pressure. then check for vacuum leaks. make sure the throttle plate is clean on both sides though with no residue and wipe around inside of where plate touches. also you can't have any holes between the throttle plate an dmaf sensor.

The check engine light is not on will there still be a code to retrive? The only light that is on is engine coolant but that has always been on since i bought the car

it cold be an idle air control valve then if you have done everything i've suggested. you should fix the engine coolant light as that could give aproblem as well.but recheck for codes, most auto parts stores do it for free.
