It sounds like you have done everything Unfortunately it is hard to diagnose because al of the above is what I would have done
I have a 2000 Hyundai Elantra and had a similar problem and I took the car to Cotterman transmission
(because it would hardly go engine rattled and lurched and stalled) they put an electronic diagnostic and said I had a mis fire on cylinder 2 and 4
I bought the best spark plug wire and boot kit and 4 plugs and replaced and it runs like a top!
It almost sounds like you have bad gas I would remove the air cleaner and spray starting fluid
into the carb while car is running ad see f it smooths out this will tell you if it is gas
Best of luck

Have someone check the idle sensor. I had to have mine replaced along with another that I don't remember which one is was.

No codes? Checklist: MAF: Mass Air Flow Sensor, MAP: Manifold Absolute Pressure Sensor, Engine Valves/Low cylinder compression, Fuel Injectors, Fuel Pressure, Tire pressure, vacuum leak(s), PCV: Polution Control Valve, Purge Control Solenoid Valve PCSV stuck open/leaking, Intake Air Hose leaking, Engine Coolant Temperature Sensor, Intake Air Temperature Sensor, etc. etc. etc..
Go to http://www.hmaservice.com/ and register (vehicle by VIN). Afterward, you'll have access to technical information (manuals, wiring diagrams, service bulletins, etc) about your vehicle.

P0301 - Cylinder 1 Misfire Detected.
Possible Causes:
- Improper spark plug at cylinder #1
- Insufficient compression at cylinder #1
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #1
- Fuel injector #1 may be faulty
- Intake air leak at cylinder
Possible Solutions:
- Perform Injector Service
- Replaced Spark Plug #1
- Replaced Injector #1
- Replaced Ignition Coil #1
Being you have a heavy gas smell I would look into the injectors. If injector #1 is over producing it can cause a misfire. Test your compression and fuel pressure.

Some check engine lights need to be reset by the OBD-II code reader. It's also possible that you've solved 98% of your problem but there's still 1 problem left (possible clogged fuel injector?) that's pulling a different error code. (possibly P0301-P0312 misfire or P0262-P0295 injector)
Best bet is to go to 1 of the auto parts chain stores that provide free diagnostic tests. If it's just a lingering old error code it will be reset or if it's something new, you'll know exactly what the issue is.
