Avantime Fuel Consumption and Power Loss

Alright Avantime gurus, listen up! My 2003 Renault Avantime, gasoline engine, is giving me fits. Mileage is about 120090 km. Fuel consumption is way up, engine power feels like it's gone on vacation, and it even stalls at idle sometimes. Plus, I'm seeing smoke when I accelerate. I suspect a faulty injector, maybe a bad cable or plug connection. Anyone else seen anything like this? Is it a common issue?

Sounds familiar! I had similar issues with my Avantime (though it's an older model). Higher fuel consumption and lack of power, that's exactly how it started with me. Did you check for any fuel leaks or any error codes?

Fuel leaks, no, I haven't noticed any. Error codes...hmm, I haven't plugged in the diagnostic tool yet. Where exactly did you experience the fuel leak, if you had one?

I didn't have a fuel leak, but I did have a defective connection! That was the culprit. Honestly, I'd recommend taking it to a workshop if you're not comfortable checking all the connections yourself. Could save you a lot of time and headache.

Thanks a lot! I think I'll do exactly that. I'll get it to a shop and have them check those connections. It turned out to be a defective connector, and the repair cost me 95€. Thanks again for pointing me in the right direction!
