P0443 is for the purge valve circuit, the valve behind the throttle body. check the "PCM 1" fuse under the hood first. unplug the valve and check the pink wire for voltage with the ignition on. also check the pins in the connector and make sure there not bent. didn't you just replace it not too long ago?

I believe that the purge valve has been replaced. I'd also inspect the connector and make sure that the wires aren't backed out of it since it was un-plugged to replace the purge valve.

I'd still check the wires going to the purge solenoid just to make sure that there isn't a wire that's half in and half out of the connector, giving you an intermittent problem, only takes a second to look 
Funny how you got a code for the purge valve circuit after the purge valve was replaced.

This morning the engine light come back on. I getting really tired of this and get me pissed off. Cuz I been paid from what shop do the inspection for.
The code SHOW is P0442
EVAPORATIVE EMISSION SYSTEM LEAK DETECTED (SMALL LEAK)
Tell me where it cause and why they do that? I really want to get all off the code. I been check everything it look so good nothing damage. I dont know what is come from.

unfortunately, if you can't see anything physically, and everything is tight, it probably requires test equipment such as a mild air pump, scan tool, and possibly a smoke machine (don't try pumping compressed air into your gas tank or you will blow out the pressure sensor on top of the gas tank and be dropping the tank to replace one of those).

Lets see what I been doing today. Want you see careful what I been had done. I already replace new purge valve, new design with Evap Vent Valve Cansitors with small filter box. Run with some 5/8 heater hoses too. I test all electric connect the wires. They are good connect. I did use ligh tester with alll of wires and fuse box too. Itis all good. I dont know why the engine light come back say Code P0442. I might fedd up and take to bitch dealership let them do it.
also check the little green screw-on cap above the throttle body
