I have had the timing belt changed and a full tune up last summer. It began to hesitate when going up hills or accellorating to get onto the freeway. Now it is hesitating when going 25-45mph. No codes have been showing up by the dealer or personal mechanic. I don't know what to do to fix the problem. Can someone help me? Thanks

Thank you. Since the car does not hesitate at an idle, how would I check the fuel pressure when driving? Thanks for your time.
