Honda BR-V Engine Jerking
Summary of the thread
A 2022 Honda BR-V with a gasoline engine is experiencing uneven running and jerking during acceleration, accompanied by a check engine light. The issue could be related to spark plugs or the air filter, but an exhaust leak is also suggested as a possible cause. A cracked manifold in the exhaust system was identified as the problem, and fixing it resolved the issue, restoring smooth engine performance.

An exhaust leak, huh? I hadn't considered that. Where exactly on the exhaust should I be looking? And would that cause the stored error code?

Well, in my case, it was a cracked manifold. The sensor readings were all over the place because of the leak, which triggered the light and code. Best bet is to take it to a workshop, they'll smoke test it and find the leak in no time. Much easier than crawling around under the car yourself. If you keep driving like that, you will damage the timing belt or even the fuel injectors. A friend of mine had the same issue and didn't get it checked for a long time, and the repair costs were really high.

Thanks a lot! I really appreciate the help. I took it to the workshop as you suggested and they found a leak in the exhaust system, just like you said. Cost me 265€ to fix. Runs like new now!

Sounds frustrating! I had a similar issue with my old Opel Astra, but it was the diesel version. Check engine light, jerking, the whole shebang. Turned out to be a leak in the exhaust system. Made the engine run like it was trying to juggle chainsaws. Have you looked at the exhaust?
