Corsa's Misfire Mystery: Engine Shutdowns & Power Loss

Hey there! I had a somewhat similar experience with my 2017 Vauxhall Astra (I have some experience working on cars as a hobby). My symptoms were pretty much identical, misfiring, power loss, and that annoying jerking during acceleration. Turned out to be a faulty fuel injector. Took it to my trusted local workshop, and they diagnosed it using their diagnostic tools. The fix involved replacing the defective injector, cost me around 515€ including parts and labor. It's been running smoothly ever since. Could you share if you've had any diagnostic codes read? Also, which engine variant does your Corsa have? This would help me tell you if your issue might be similar to what I experienced with my Astra.

Thanks for sharing that! Yeah, I'm having those exact same symptoms with my Corsa. I've actually got 294540 KM on the clock, and the last service was pretty recent. Haven't gotten the diagnostic codes read yet, but I'll definitely get that checked out. Your fuel injector issue sounds spot on with what I'm experiencing, I'll make sure to mention that when I take it to the shop. The price you mentioned seems reasonable if it fixes the problem. Did you notice any warning signs before the injector completely failed?

Hey again! Yeah, looking back at my Astra's situation, there were definitely some warning signs before the injector completely gave up. At first, it was just minor stuff, like a slight hesitation when accelerating from a stop. But it gradually got worse over about 2-3 weeks. The exhaust smell you mentioned was actually one of the first things I noticed too. My Astra had around 250,000 KM when this happened, so pretty similar mileage range to your Corsa. The funny thing is, I also had just gotten it serviced a few months before the issues started. Since you're experiencing such similar symptoms, I'd bet money it's either the injectors or something in the fuel delivery system. Quick tip from my experience, when you take it to the shop, ask them to check the fuel pressure too. In my case, they initially thought it might just be a clogged injector that needed cleaning, but it turned out the injector itself was shot. Could've saved some diagnostic time if I'd mentioned that earlier. Keep us posted on what they find! Always interested to see if these issues end up being similar across different models.

Thanks so much for all that detailed info! It's really helpful to hear about those early warning signs, now that you mention it, I did notice that hesitation when accelerating from a stop about a month ago, but didn't think much of it at the time. I'll definitely get those diagnostic codes read first thing tomorrow and make sure to ask about checking the fuel pressure too. Really appreciate you taking the time to share your experience, it's given me a much better idea of what I might be dealing with. Will update the thread once I know what's going on with my Corsa. Thanks again for all the help!
