P0441 = EVAP PURGEFLOW MONITOR that means insufficient or excessive vapor flow detected during evaporative system .
P0304= a misfire in cylinder # 3 answers to these p0441 a bad gas cap possible , and p0304 possible bad coil on cylinder #3, try clearing codes and see if they show back up or you get bad performance , then try replacing gas cap and then coil pack . I really hope this gets you on the right track .

check idle speed control motor .idle air control

I'm guessing you have a timing problem. Have that checked first.

Inspect pugs for propper gap, cracks... check wires for arching and replace as needed. Verify firering order is correct.

The ac compressor pulls a good number of horses from a 4 cyl engine.
Any minor performance problem is amplified when the ac is running.
You probably have a weak spark plug or wire, or an issue with an injector.
Is the check engine light coming on when it is rough ?

Check on intake silicon gaskets, upper and lower. About $18 at autozone

I had same problem...Clean thottle body...Take hose from air cleaner off,two silver clamp...Take cover off throttle cable,open butterfly,wet cloth with carb cleaner,Wipe inn side,clean soot out...Done....I have 2004 PT 26000 all city miles

if you have replace the purge solenoid the problem is either the vaccum supply hose is loosing vaccum or the purge side is hose is either blocked or cracked.
