Ford Everest rough idle
Summary of the thread
A 2003 Ford Everest with a gasoline engine is experiencing rough idling, stalling, and poor fuel economy, with a check engine light indicating incorrect fuel composition. Initial attempts to resolve the issue, such as using fuel injector cleaner and checking for vacuum leaks, were unsuccessful. A suggestion to inspect cable or plug connections led to the discovery of a corroded connector on a fuel mixture sensor, which was replaced, resolving the problem.

Interesting! Cable or plug, huh? Which component are you talking about exactly? I've visually inspected most of the connections I can easily reach, but maybe I missed something specific. Was the error stored in the error memory in your case?

Yeah, the error was stored too. Sorry, I can't tell you exactly which component it was in my case, but the workshop guys identified a loose connection which caused the issue. Maybe you should visit a workshop. They should be able to locate the problem relatively easy with their tools.

You were spot on! Took it to the shop, and it turned out to be a corroded connector on one of the fuel mixture sensors, just like you suggested. New connector and labor came out to 95€. Runs like a champ now. Thanks a million for the tip!

I had a similar issue with my Everest (gasoline model). Same symptoms - check engine light, rough idle and everything. Have you checked the cable or plug connection of the component, maybe it's defective? I heard it's a pretty common fault.
