Land Cruiser rough idle and stalling

I'm having trouble with my 2003 Toyota Land Cruiser with a gasoline engine. Only 41849 km. It's hard to start, fuel consumption is up, power is down, the idle is rough, and sometimes it stalls. I think it might be the injection nozzle system, maybe a clogged valve. Anyone seen this before?

Whoa, that sounds rough! I had something kinda similar happen with my Land Cruiser (don't remember the exact year). Hard starts and the engine just didn't feel right. Have you tried any fuel injector cleaner? Might be worth a shot before diving into anything major.

Thanks for the quick reply. What specific fuel injector cleaner did you use, and how did you apply it? Did you notice any side effects?

Honestly, I just grabbed whatever injector cleaner was on the shelf at the auto parts store. Poured it in with a full tank of gas, like the bottle said. Didn't really fix it completely though. Ended up taking it to a mechanic, and they confirmed a dirty injector was the problem. Best to get it checked out properly!

Thanks for the help. I took it to a shop, and they confirmed a defective injection nozzle and replaced it. Total cost was 515€.
