History of repair: I took van in for a basic tune up about 2 months ago. Once I received the van back I notice a hesitation while accelerating, after about a week the engine service light turned on. I returned to the service repair shop for another diagnostic and repair. The van had a multiple miss-fire-fault in the ECM. The service center suggests that I replace the air flow sensor to correct the problem. I had them to make the repairs, and a month later the hesitation in acceleration returned.

Do you have any suggestion to my problem?

Unplug the mass air flow sensor and see if you get more power. You could have a bad one. Also check to make sure the air inlet snorkel is securely attached. If it is loose it will do the same thing. If I have helped you feedback and votes are greatly appreciated
