Hi there. The issue that maybe happening is the are fuel injectors that are not firing and there is a vacuum leak on the engine. Possible multiple sensors are not working causing the P2196 (https://www.obd-codes.com/p2196) and P2198 (https://www.obd-codes.com/p2198) codes to...
Hey there. If after replacing all those items, the cylinder #6 misfire code remains, then there are a few other possibilities. This could possibly be a fuel injector fault. The injector can be clogged or simply worn from age and...

Hello there, many faults will cause a misfire in cylinder 6 with your 2007 Lexus LS460. You have done great in replacing the coil pack as these can defiantly cause the misfire. Other potential causes are the spark plugs (https://www.yourmechanic.com/services/spark-plugs-replacement),...
All these codes point to engine misfires. You should pull the spark plug wires (https://www.yourmechanic.com/services/ignition-cable-spark-plug-wires-replacement) to see if oil is on the spark plug wires causing the misfire. You would need to replace the valve cover gaskets (https://www.yourmechanic.com/services/valve-cover-gasket-replacement) and spark...
The codes P0300 through P0306 are for misfires of random cylinders or different cylinders. The second code P1456 is for the evaporative fuel tank system having a leak somewhere in the system (https://www.yourmechanic.com/article/how-to-diagnose-a-fluid-leak-by-mark-vallet). Since you are getting random misfires, then...
