A hesitation on acceleration may be caused by a failing throttle position sensor (TPS). If the problem is confirmed to be a failed TPS replacement of the failed sensor will be required.

Engine pops and sputters when pulling off. Once engine gets above 2000 rpms the engine runs fine. Car went to several shops, including two dealers before finding someone ( it was not at a dealer either) who could repair it. Cost me $500 to get the problem diagnosed and repaired not to mention the tune ups the other shops insisted the car needed.
