2000 Windstar runs extremely rough when only a few gallons left in tank - misfires and won't run faster than 20-30 mph. Have tried adding the dry gas/injector cleaners to no avail. As long as more than quarter tank, it runs fine. Any ideas?

Try doing a fuel pressure test, but it sounds like you have a bad fuel pump. The lower the gas level gets, the harder it is on the pump. It sounds like it needs replaced.

Suggested Repair

Perform a fuel pressure test. The symptoms point to a failing fuel pump that struggles when the tank is low; replace the pump and the fuel filter together.

Conversation Summary

A 2000 Ford Windstar runs extremely rough, misfires, and will not exceed about 20-30 mph when only a few gallons remain, but runs fine above about a quarter tank. Fuel additives did not help. Experts recommend a fuel pressure test and say the fuel pump likely needs replacement, with the fuel filter changed at the same time.
