Well i have this little problem with my car, everything works ok when im rolling with the A/C on.. but if i have to stop at a red light or something the revs go down to 100-200 rpm and then they go up to normal idling revs about (850-900) it keeps well by a minute or so and then the revs go down again, it never turns off but it shakes a lot when this pass. Im actually running with the stock ecu, VE injectors, DE maf. Can be this an ECU issue?
Hope you guys can help me out because here were i live is hot as hell in the summer (113-118°F).

Check the idle control Valve. When i had my P11 Primera it use to do that. Come to a stop especially with the AC on bog down to about 200rpm then it would sort it self out. Had to change idle control valve in the end.
Other than that you are using a stock DE ECU or a VE ECU?
You are probably having a wiring issue with you FCID valve. It's the small plug (probably purple) on your AAC valve. You can check it's operation by unplugging it and putting voltage from your car battery to it's terminals with your engine off. You should should hear a click sound.
Putting the switch to on possition you could check for resistance between wires using negative ground. One wire is connected to your AC relay and the other travels to ground through your ecu.
