idlle problem

Im not an expert but after changing the plugs and everything you mentioned and also everything is basically stock except your CAI which could be the problem so What I would suggest is getting your car a chip and having it dyno tuned and maybe even think about going with a diablo preditor chip. Thats what I have. Remember Im no expert but this is just my opinion. Hope I helped in some way.

i wouldent get a tune or a tuner yet either one of those wont solve the problem. i would check your front 02 sensors they control the fual mix. i would do that before i did anything expensive like get a chip and a tune
