Maverick Hybrid Fuel Consumption and Stalling

Interesting problem. I experienced similar symptoms with my 2018 Volvo XC60, though it was a diesel. High fuel consumption, reduced power, and occasional stalling. Have you checked the cable or plug connections to the fuel injectors? A defective connection can cause those exact symptoms. It's like a loose wire in a lamp; sometimes it works, sometimes it doesn't.

Thanks for the tip! I haven't checked the fuel injector connections specifically. Where exactly should I be looking, and is it something I can easily access without special tools? Is there a specific system I should be looking at?

On the Volvo, the fuel injector connections were somewhat buried under the intake manifold, but I believe on your Ford Maverick it might be more accessible. It is likely a few hours job. If you are not very experienced I would suggest you have a workshop carry out the work. To be honest, given the hybrid system, it's probably best to have a professional diagnose it properly to prevent additional problems.

Thanks for the advice! I took it to the workshop, and you were spot on. It turned out to be a defective cable connection to one of the fuel injectors. Repair cost was 95€, and it runs like new now. I really appreciate the suggestion!
