My 1998 Ford Windstar Mini Van started to sputter and it lost speed and wouldn't accelerate. Answer?

First thing...is there gas in the tank? (You'd be suprised at how often that's all that is wrong.) Otherwise, yeah it could be an air/vacuum line. Whatever is wrong, you can be pretty sure it means that the engine isn't getting enough gas. Best scenario...water in the gas. But it would have to be a lot of water. It doesn't sound like it happens all the time, right? The fuel filter could be clogged up, or the oxygen sensor or m air flow sensor could be messed up, so the engine computer is getting false signals. That would likely make it sputter all of the the time. I had a Pontiac that started sputtering/losing power, and it was just the little vacuum line that ran to the MAF (m air flow) sensor. If it just hppened once, or just once in a while, put some dry-gas in it, and try to keep the tank more that half full. If it still does it, check the fuel filter, and the oxygen sensor. If it's just a vacuum line, you may not even have to go to the garage, if you or someone who knows a little about cars looks the whole engine over. If you see a little rubber hose disconnected anywhere, find where it connects, and plug it back in. You don't need a garage for that; if it's something else, to the shop with it.
