Avensis Fuel Consumption and Stalling

I'm having some serious issues with my 2003 Toyota Avensis (gasoline engine). It's got about 83000 km on it. Lately, the fuel consumption has gone through the roof, the engine feels like it's lost a ton of power, and sometimes it even stalls when I'm idling! Plus, I've noticed some smoke coming out when I accelerate. I'm no mechanic, but I checked the air filter and it seems fine. Any ideas what could be going on? It's driving me nuts!

Sounds like a fuel injection problem. Have you checked the cable and plug connections to the injectors? A defective connection there could cause those symptoms.

Thanks! Where exactly are those cable and plug connections located? Is it something I can easily check myself, or am I better off taking it to a professional?

They're on the fuel rail, connected to each injector. If you're not comfortable working on the fuel system, I'd suggest taking it to a workshop. Fuel injection issues can be tricky.

Thanks for the advice! I took it to the shop, and you were spot on. It was a dodgy plug connection on one of the injectors. They cleaned it up and charged me 95€ – much cheaper than I feared! Runs like a dream now!
