I have a 2020 Tahoe with a 6.2L & 10 speed trans, I have a P306 misfire and engine light flashes and traction control light on. I have replaced the spark plug, and have switch the wire and coil with a different cylinder and still get a P306 misfire and traction control light. Also, when this is going on, a noise is coming from the engine/ transmission. When you clear the code, the noise goes away but will come back when lights come on. Any ideas?
