LandCruiser Engine Stalling Idle Reduced Power

I had similar issues with my LandCruiser. Stalling at idle and reduced power sounds familiar. Did you check the fuel pressure sensor? A bad sensor can trigger the check engine light and cause the fuel pump to behave erratically. It's like a conductor getting bad readings from the orchestra, and making the whole thing fall apart. Is your fuel efficiency worse than usual?

Thanks for the quick reply. Where exactly is the fuel pressure sensor located? And is there a way to test if it's faulty before replacing it? I'm trying to narrow down the possibilities.

It's usually on the fuel rail, but since you just changed the filter, double-check all the connections there first. Make sure everything is seated properly. Otherwise, testing the sensor properly requires specific tools like a multimeter and the vehicle's service manual to check voltage readings, so if you are not equipped or trained, I recommend taking your car to the workshop for professional diagnosis. It is like trying to perform surgery with kitchen utensils!

Appreciate the help! I followed your advice and had the car checked at the workshop. Turns out, it was indeed the fuel pressure regulator. It cost me 45€ to get it sorted. Thanks again for pointing me in the right direction.
