What's your problem?my van loose power while driving

Check your U-Joints on the Drive Line... This happens when the Joints are going Bad

Given the vehicle,age & all the terrible
transaxle problems on a windstar & vehicle
it replaced

Your transaxle has failed

Having once owned a trans repair shop

Get rid of it & never buy another van type
vehicle,any brand

wow...was looking for something else and came across the "slam door" fix...Had this problem so I tried it...and it works!!! Thanks!!!

problem could be faulty over drive switch.the switch could have a short or you could have torque converter problems or TCC solenoids problems.save time and money take vechicle to a transmission shop or garage, let them code scan do a diagnostic check see what causing transmission not go in over drive.

You always check for codes & resolve those
issue first,when ever a check light comes on.

Rough idle / stall at idle Check for vacume leaks & split intake tube or loose clamps on intake. Noise put spot of grease on drive belts if noise goes you may need new belts or a tighten up.

When it comes to loosing power the only thing left is your Carb. or your injectors. your Catalyitc converter won't make you lose power, that is part of your exhuast system. run some Carb or Injector cleaner in your gas tank next time you fiill up, I use a pint of Acidton per 15 gallons but I don't suggest you do that, buy some injecter cleaner at pep boys.

Could be a number of things honestly. Could be a blown head gasket or it's starting to go up. Could also be as simple as a new fuel filter and a professional fuel system cleanse. I would take it to a repair shop, one that you trust, and have it looked at. If the head gasket is repairable, it won't be that much unless the whole thing is blown, but the car would have no power at all then.

"Loud humming" could describe many of the noises that your minivan may make. Let's start with the basics: do you hear the noise only when the van is in motion or also when the van is stopped? If you can hear the noise even when the van isn't moving, you're most likely looking at something in the engine compartment. Your serpentine belt and the alternator bearings (and, to a lesser likelihood, your power steering pump) are all sources of noise "in there." An A/C compressor on its last legs may also vibrate and cause a humming sound, though that's usually described as more of a "growl."

If you can only hear the noise when the car is in motion, the next question is whether it changes pitch/volume due to engine speed or due to road speed? For example, does the noise get quieter (momentarily, perhaps) when the transmission shifts gears? Or, does the noise simply get louder/change characteristics in a linear way as the van gets faster and/or slower?

Depending on the mileage on your van, the transmissions have been known to get quite noisy after a while, especially if you are doing sustained high-speed driving. The solution for that particular problem isn't cheap, as it involves replacing or rebuilding the transmission (the shift bands may be fine; the noise is caused by bearing wear, seal failure, and other sundry issues that still require pulling the transmission). A less expensive problem is that you might have a problem with one of your tires--a tire with separating belts may make a noise like this as it slowly tears itself apart. If you hit something hard with the undercarriage of the van, you might have a drive shaft that's slightly bent and hence is causing some sympathetic vibrations in the car because it's out of balance.

Depending on the cause, your humming sound may be one of those things that comes with driving an older car--or it may be a sign of the imminent failure of something serious. It's worth getting things checked out again to try to find the cause of the problem. You'll feel a lot better knowing what it is, even if it's something you choose not to fix.
