Cylinders 3, 4, and 6 missfiring

Question by wcierra posted 5 months 3 weeks ago in Toyota

I have a 2002 Toyota Camry V6 with cylinders 3, 4, and 6 misfiring.

My brother replaced both knock sensors 300 miles or so ago.

The vehicle shakes when stopped and there is a new sound coming from the engine.

We are wondering if anyone has any insights into the problem and/or knows which knock sensor goes to which cylinders. We could not find any information concerning this online.

Thanks in advance.
