CUTS OUT AND SPUTTERS WHEN Y0U GIVE IT THROTTLE RECENTLY ADDED COLD AIR INTAKE

I dont know bought the car 2 days ago for 400$ but I just replaced all spark plugs of which cyl 2,6 had 1 type cyl 4 another,cylinders 1,3,5,yet another some improvement.look like they have replaced the throttle body,could it be the IAC pendle is not seated?It is costing to keep replaceing sensors randumly

have you tried cleaning it?maybe has carbon build up.sometimes cleaning them will help.there is an instruction sheet that comes with a new one,the pintle,you can screw it in and out,but there is a spec on how far it sticks out of the valve.you may want to stop at autozone and look at the sheet that comes with the new valve.
