yes, hi, and thanx for the donation, It sounds like your intake may just be dirty, start by cleaning the throttle body and throttle plate, you'll want to clean the idle air control valve of any carbon on it or the bore that it sits in, check the air intake hose coming from the air filter box for any cracks and holes(replace if necessary). replace air filter if necessary, since you already did plugs and wires, you should be good to go, if it does not clear up,please comeback and go further if need be.
thanx
