Hello Scotty! Love the videos as always. I have a 2003 Toyota Camry LE Automatic with almost 253,000 miles. It won't rev passed 3000 RPMs in park or any gear. I have codes PO300, PO303, and PO304. There is a strong gas odor smell too. Is this fuel related? Thanks!

So, you're getting misfires - and a lot of them if you're getting those codes. There are a number of things that could cause them, so there are quite a few things to check: (below is from https://repairpal.com/obd-II-code-chart )
Common Problems That Trigger the P0300
- Worn out spark plugs, ignition wires, coil(s), distributor cap and rotor (when applicable)
- Incorrect ignition timing
- Vacuum leak(s)
- Low or weak fuel pressure
- Improperly functioning EGR system
- Defective Mass Air Flow Sensor
- Defective Crankshaft and/or Camshaft Sensor
- Defective Throttle Position Sensor
- Mechanical engine problems (i.e.—low compression, leaking head gasket(s), or valve problems
