Aygo Diesel Engine Running Lean

My 2005 Toyota Aygo diesel feels like it's running lean. I've noticed a drop in power, the check engine light is on, and it's running rough, especially when accelerating. Thinking it might be a dodgy injector?

Sounds rough. I had similar issues with my Aygo a while back. Check engine light, loss of power... the whole shebang. Have you looked at the intake manifold? Could be a vacuum leak messing with the air-fuel ratio. It felt like driving a kangaroo when accelerating - constantly jerking around!

Interesting. I hadn't thought about the intake manifold. Where exactly should I be looking for leaks, and is there an easy way to check?

Honestly, tracing vacuum leaks can be a pain. It's like finding a needle in a haystack, but with engine grease instead of hay. I messed around with it for a bit, but in the end, I caved and took it to a workshop. Turns out it was a faulty injector. Cost me a bit, but at least it's sorted now.

Thanks for the heads-up! I'll probably take it to a shop then. My local garage said it was the fuel injectors. Quoted me 515€, but at least it'll be fixed. Appreciate the advice!
