Car runs good just every once in a while it acts like it dont want to go. Usually if you let off of gas and down shift it will get better on its own, other times I have to pull over and turn off car, restart and it goes fine. Smells like gas. car sat awhile. Fuel pump, fuel filter, coil packs, spark plugs and wires are all new.
Replace the purge valve it self or the purge valve solenoid

P0441 : Evap. Emission System Incorrect Purge Flow
General Description
The evaporative emission control system prevents hydrocarbon (HC) vapors from the fuel tank from escaping into the atmosphere where they could form photochemical smog. Gasoline vapors are collected in the charcoal canister. The ECM controls the Purge Control Solenoid Valve (PCSV) to purge any collected vapors from the canister back to the engine for combustlon. This valve is actuated by the purge control signal from the PCM and controls fuel vapor from the canister to the intake manifold.
Possible Cause :
● Leakage on hose to PCSV
● Defective PCSV

It is always best to start simple on a lot of these things. This code indicates that somewhere in the evaporative system you have a leak that has set off the code. The gas cap is the most common culprit and that is where I would start. Buy a new gas cap and put it on. It may and should solve your problem. A lot of gas caps have rubber seals that do wear out over time. If this does not solve your problem simply use a search engine and type in p0441 a wealth of information will pop up. There are other possible causes and solutions but that's where I would start (with the gas cap)

sound like the throttle body needs cleanig out and adjust the air flow meter ,both items are on the engines air intake system

There is an evap purge valve located in the back of the driver side of the engine. This valve needs to be replaced. Had the same code a couple weeks ago. Replaced that valve and the problem was fixed. Hope this helps.

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.
Evaporative Emission Control System Incorrect Purge Flow
What does that mean?
This indicates that a part of the EVAP control system is no longer functioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
EVAP emission canister purge is controlled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere. A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.
Symptoms
Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light.
Causes
A code P0441 could mean one or more of the following has happened:
With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

Car is a 2000 Hyundai Tiburon 5 speed 4 cyl. Also noticed the purge flow valve under the hood has already been replaced.
