I have a 2004 expy with 250,000 miles on it. Last week it started hesitating when accelerating then stopped then a few days ago it started idling really hard and was also hesitating but would stop after driving for awhile. We put some fuel injector cleaner in it but and then decided we should replace the fuel filter as it has never been done. We did that two days ago. The hard idle is gone but it does still hesitate a bit when first driving it between 1500 and 2000 rpms. I have purchased some fuel system cleaner to try as it seems fine beyond that. Any other suggestions?
