Arrow Rough idle with AC on?

I have an 01 dx, 5 speed, odometer reads 155k, but motor is not origonal to the car, unsure oif milage, seller claimed th ecar had new timing belt installed, I recently did NGK irridium plugs, Fujita intake, and WS2 catback. When I am stopped at a light ideling with the ac on, the car has a rough idel, like a v8 with a cam, itll lope, if I am driving its fine, and if I turn the ac off its fine, th ecar never stall sout, it feel sliek its damn close, not a huge issue yet, but, i is annoying and Id liek to fix it, any ideas?

Ok, will do, is there an idle adjustmnt on these cars? Im goign to go pick up a Haynes manual today for it, but, it seems like I did get worse after I put that intake on the car, figure maybe I hit it when I put ti on there.

there is idle screw but you should never have to adjust it cause its all computer controled. just clean everything out, then do the ecu reset and idle learn when youre done.
