Camry engine misfire exhaust leak

My 2005 Toyota Camry with a gasoline engine has been running really rough lately, almost like it's misfiring. It jerks a bit when I accelerate. The check engine light is on, and I pulled a cylinder misfire error code. I've checked the air filter and it's clean. Could it be fuel injectors or something more sinister like the crankshaft sensor or even the timing belt?

I had a similar problem with my Camry. Do you notice any unusual exhaust smells or noises? A leak in the exhaust system can cause all sorts of weird engine behavior. Have you inspected the exhaust manifold or any of the pipes for cracks or rust?

That's an interesting thought. I haven't specifically checked for exhaust leaks, but I will now. Would an exhaust leak really cause those symptoms, even the jerking? Are there any common spots on a Camry exhaust system that tend to fail?

Yes, it is entirely possible. An exhaust leak can definitely cause those symptoms. On my Camry, the issue was with the exhaust manifold gasket. I would strongly recommend that you check with a qualified workshop.

Thanks a lot for the suggestion. I took it to the shop and you were spot on; they found a leak in the exhaust system. The bill came to 265€, which wasn't too bad. Runs like a top now!
