2001 Windstar-Running rough after the check fuel cap light came on. Cap is tight. Add additive to gas in case of water in gas. Still running rough.
Check Fuel Cap light came on. Cap was fine. Was on for a couple days. Then
started running rough. Idling at around 700 RPM and missing. Thought had
bad gas, so added fuel additive/injector cleaner to next tank of high octane
gas. Still running rough. Plugs looked fine.
