I've checked the wiring and connectors as best I can. I don't have the error code right now, but I'll get it soon. Could a bad cable or plug really be the problem?

A dodgy connection can mimic a faulty sensor! Like a loose lightbulb that flickers. But the sensor itself might just be old. Get it checked by a professional to be sure. They'll have the right tools.

I went to a workshop. They found a defective cable or plug connection related to the oxygen sensor, like you said. The repair was 95€ Thank you!

A bad O2 sensor on an older Clio could cause those symptoms! Have you checked the wiring and connectors? A loose or corroded connection can throw things off. Do you have the error code number? Is the car running rough, or just using more fuel?
