Honda City's Smoke & Stall: Warning Signs You Can't Ignore

Hey there! I had similar issues with my 2016 Honda Civic (gasoline). The symptoms you're describing sound exactly like what I experienced last month. Black smoke, stalling, and that awful jerking during acceleration, been there. Took it to the garage, and turns out it wasn't the fuel pump. The main culprit was a defective wiring harness connected to the fuel injection system. The connector was corroded and causing intermittent electrical issues, which messed up the fuel-air mixture. That's what was causing all those problems. It was a serious issue that needed immediate attention because it could've damaged other engine components if left unchecked. The technician showed me how the corrupted signals were causing the engine control unit to malfunction. The repair involved replacing the entire wiring harness assembly and cleaning the connectors. The job took about a day, but it solved all those symptoms you mentioned, no more black smoke, stalling, or power loss. Keep in mind electrical issues can be tricky to diagnose, so make sure you get a proper diagnostic scan first. Hope this helps!

Hey, thanks for sharing your experience! That wiring harness issue sounds exactly like what I'm dealing with. The mechanic sorted it all out for me too, and my City's running smooth now, no more of that scary black smoke or stalling. Quick question, do you remember roughly how much you paid for the repair? Also, has everything been running okay since then, or have you noticed any other quirks pop up?

Hey! Glad to hear you got your City fixed up too! Yeah, my Civic's been running like a dream since they fixed that wiring harness issue. I paid 95€ for the repair, honestly, it was worth every cent considering all the trouble it was causing before. And nope, absolutely no problems since then! The black smoke's gone, no more stalling, and the engine's purring like new. It's amazing how such a small electrical issue can cause so many problems, right? The fuel pump they initially suspected turned out to be perfectly fine, it was just getting wonky signals from that damaged wiring. I've put about 3000 km on it since the repair, and everything's working exactly as it should. Fuel consumption is back to normal too, which is a nice bonus for my wallet! Just goes to show how important it is to get a proper diagnosis, sometimes the obvious suspect (like the fuel pump) isn't actually the culprit. Hope your City keeps running smoothly too! These cars are usually super reliable once you sort out any electrical gremlins.

Thanks for that detailed follow-up! Really reassuring to hear your car's still running well after the fix. Actually, just got back from the mechanic yesterday. You're right, these repairs are totally worth it. My bill came to about 85€, a bit less than yours, and honestly, I'm just relieved it's sorted. The mechanic was really thorough and even showed me the old damaged wiring, it was in worse shape than I expected! Funny thing is, I was so convinced it was the fuel pump that would need replacing. Glad I was wrong about that, saved me a bunch of money! The car's running amazingly now. Did a short trip today, and it's like driving a different vehicle, smooth acceleration, no smoke, and that horrible smell is gone. Thanks again for sharing your experience. It really helped me understand what I was dealing with and not panic about needing a major engine overhaul. Here's hoping both our cars stay problem-free for a good long while!
