Epica MAF Sensor Issue

Hey, I'm having a frustrating issue with my 2006 Chevrolet Epica (gasoline engine). It only has 41159 km on it. I think the mass air flow meter is defective. I'm experiencing higher fuel consumption, the engine stalls at idle sometimes, the check engine light is on, and there's even some smoke when I accelerate. Could it be the MAF sensor? I checked the air filter and it seems clean.

A 2006 Chevrolet Epica owner is experiencing issues such as higher fuel consumption, engine stalling at idle, a check engine light, and smoke during acceleration, suspecting a defective mass air flow (MAF) sensor. Another individual with similar symptoms confirms that their problem was indeed the MAF sensor, which required replacement after cleaning attempts failed. The original issue was resolved by replacing the MAF sensor, restoring the vehicle's performance.

Did this summary help you solve your problem?

Sounds familiar! I had similar symptoms with my Epica. Check engine light, rough idle, and definitely noticed the fuel consumption creeping up. Have you noticed any decline in performance?

Yes, absolutely a decline in performance. Did you ever figure out what the problem was? Was it the MAF sensor?

Yep, for me it was the MAF sensor. I tried cleaning it first, but no luck. Eventually, I had to replace it. I'd suggest getting it checked out by a workshop to be sure.

Thanks for the advice! I took it to the workshop, and you were right – it was the MAF sensor. The whole repair cost me 365€. Runs like new now!
