Our van occasionally bucks or hesitates from a stop. This just started about a month ago. I took it in for service the other day and they recommended a throttle body cleaning. They said that's most likely the problem. 60k on the van. Well apparently it wasn't the cause, because when we picked it up on the way home it did it again. I called service and they asked about the gas I use. I use and have used BP for years in this van and all my other vehicles. So I don't think it's the fuel. I told him I'd try another brand and see if the problem is still there. If so, I'll bring it back in.
Does anyone have an idea what might cause this ? No codes or check engine light and it's an intermittent problem. Platinum plugs. Runs great and good fuel mileage, just the occasional bucking/hesitation. More like bucking to me.
thanks
