If the fuel filter was old, what else might be old? This concern could be caused by a lot of things; worn spark plugs, spark leak or high resistance in the plug wires, dirty mass airflow sensor, plugged air filter, damaged catalytic converter.... the list goes on. Do you have and trouble codes stored? Are there any other symptoms? How does it start? How does it idle? Is it worse when the engine is warm or cold? There are many possibilities so please provide some more information and we will try to help you out. Go ahead and check the transmission fluid. Should be pink and clear. Put some on your finger and rub fingers together. Feel any grit? I only say this because you just purchased the car. I do not believe your problem is in the trans.

Also, engine size will help, is it the 2.4 or the 3.1?
