LandCruiser diesel performance decline

Hey, I also drive a LandCruiser, though I can't recall the exact year. I had almost the exact same symptoms a while back – the poor fuel economy was driving me nuts, and the stalling was just plain embarrassing. I remember cleaning the MAF sensor, which helped a bit temporarily, but the light kept coming back on. Did you try cleaning the sensor already?

Thanks for your reply. I have not yet attempted cleaning the sensor. What were the long-term effects after cleaning the sensor? Did the check engine light disappear permanently?

Cleaning it only gave me a brief respite, maybe a week or two. The check engine light came back, and the symptoms gradually returned. Honestly, after messing with it for a bit, I just took it to a workshop. They confirmed it was the MAF sensor and replaced it. Solved everything. Probably best to get it properly diagnosed.

I appreciate the advice. Based on your experience, I will take it to a trusted workshop for a diagnosis and potential MAF sensor replacement. Thank you for sharing your experience; it has been most helpful. The repair eventually cost me 365€.
