my car still does some stuttering action when its warm. i heard the problem might be the aac valve. what does the aac do? where is it located? and is there anyway to check if its any good?

ive already replaced my iac solenoid and it fixed my idle problem at stand still but did not fix my stutter that happens ocassionally when driving when the car is warm.

it happens intermittenly , so not all the time . if the problem were that serious id think it would happen more often

brand new ngk plugs and wires like a month ago , new cap and rotor for the dist. maf is fine , injector in the tb is fine. tps is new and adjusted properly. engine rebuilt 5000 km ago. sometimes i get a flat spot in 1st gear when i giver a lil. ecu pulls no codes

i guess ill check all my engine grounds and reset my ecu and see if it helps.
