Crider high fuel consumption and stalling

The symptoms you described, specifically increased fuel consumption, engine stalls at idle, the illuminated check engine light, and smoke upon acceleration, strongly suggest a potential issue with the mass air flow (MAF) sensor. I recommend inspecting the air intake system for any obstructions or leaks. Also, when was the last time you replaced the air filter?

Thanks for the quick reply! I checked the air filter a few weeks ago, and it looked pretty clean. No visible obstructions in the intake either. If it is the MAF sensor, is it something I could try to fix myself, or should I just take it to a workshop?

Given the potential impact of a malfunctioning MAF sensor on the air-fuel ratio and overall engine performance, I recommend consulting a qualified mechanic. While a DIY replacement might seem feasible, the diagnostic process and potential recalibration of the engine control unit (ECU) often require specialized equipment and expertise. Continuing to drive with a faulty MAF sensor can exacerbate the issue and potentially lead to further damage.

Okay, that makes sense. I appreciate the advice! I took it to a workshop, and they confirmed it was indeed the MAF sensor. The repair cost me about 365€, but the car is running much better now. Thanks again for pointing me in the right direction!
