BMW M2 Owner Seeks Help for Power Loss and Jerking

I had similar issues with my 2020 BMW M4 last year. The symptoms you're describing match exactly what I experienced, jerky acceleration, rough idle, and decreased power output. Turned out my fuel injectors were failing, causing incomplete combustion and misfires. After diagnostic tests, they found two faulty injectors that needed replacement. It was a serious issue since bad injectors can damage other engine components if left unfixed. The repair involved removing the intake manifold to access the injectors, cleaning the entire fuel system, and installing new ones. I'd strongly suggest getting it checked soon. Running lean can cause more expensive damage down the line. In my case, the car ran perfectly smooth after the repair, and the power came back immediately. For a performance car like an M2, you really want properly functioning injectors for optimal engine health. Since you're not comfortable with your previous mechanic, try finding a BMW specialist who regularly works on M cars. Given the mileage on your M2, injector issues wouldn't be unusual.

Thanks for sharing that injector issue with your M4, really helpful since I'm seeing such similar symptoms. Mine's behaving exactly like you described. Hey, do you remember roughly what the repair cost you? Also curious if you've had any other issues pop up since getting it fixed? Just trying to get an idea of what I might be looking at cost-wise and if this solved all your problems completely. My wallet's already nervous!

Hey there again! Happy to give you an update on my M4 situation since you asked. I paid 515 € for the complete injector repair job, which included parts and labor. Honestly, it was worth every penny because the car runs amazingly now. The engine performance is spot on, no more lean running issues at all. It's like having a completely different car! And to answer your other question, nope, haven't had a single problem since getting it fixed. The jerky acceleration is completely gone, idle is smooth as silk, and the power delivery is back to what you'd expect from an M car. My mechanic really knew their stuff with these performance BMWs. Trust me, I know that repair bill can look scary, but catching and fixing injector problems early actually saves money in the long run. If you let it go too long, you could end up with more serious engine damage, and nobody wants that headache! Let me know if you end up getting yours fixed, would be interested to hear if you had the same experience as me.

Just wanted to give you all an update on my M2 situation. Finally got the courage to take it to a specialist mechanic yesterday. You were right about the symptoms pointing to injector issues! Turned out I needed two injectors replaced, plus they did a thorough fuel system cleaning. The bill came to around 600 including parts and labor, a bit more than what you paid, but still better than I feared. The difference is absolutely incredible! The car runs like new again, no more jerking, hesitation, or rough idle. The power's back to what it should be, and that annoying check engine light is finally off. The mechanic was fantastic too, really knew their stuff and explained everything clearly. Thanks again for sharing your experience. It really helped me make the decision to get it fixed before things got worse. Best money I've spent on the car so far!
