So it could be a faulty engine control module and or some type of wiring problem with the ignition coils.

Hey there, Bill!
The classic case of a cranky Lexus ES350. Those trouble codes (P0351, P0352, P0353, P0354, P0355, P0356) are pointing to issues with the ignition coils in cylinders 1 through 6. Since you've already tackled the cam sensor on bank 1 exhaust, it's good that you're on the right track.
Here are a few steps to consider:
1) Ignition Coils: Given the codes, it's worth checking the ignition coils for cylinders 1 through 6. Make sure they are all properly connected, and there are no loose wires or damaged connectors. If one was problematic, it might have caused a domino effect on the others.
2) Wiring Inspection: Examine the wiring going to the ignition coils. Look for any frayed wires, corrosion, or loose connections. Sometimes, a damaged wire can cause intermittent issues.
3) Check for Spark: Confirm that each cylinder is getting a spark. You can use a spark tester or an old spark plug connected to the ignition coil to check for sparks while cranking the engine. If you're not getting a spark on a particular cylinder, it could help narrow down the issue.
4) Fuel Delivery: Ensure that fuel is reaching the cylinders. A clogged fuel injector or a fuel delivery issue could cause similar symptoms. You might want to check the fuel injectors for cylinders 1 through 6.
5) Engine Control Module (ECM): If everything else seems in order, there's a chance the ECM might be acting up. It controls the ignition system and could be a culprit if it's not sending the right signals to the coils.
Remember to double-check all your work, and if you're not comfortable with any of these tasks, it might be a good idea to consult a professional mechanic. Electrical gremlins can be tricky, but with some methodical checking, you should be able to track down the issue.
