No just the spark plugs i thought the plugs were the problem but the concern is still present pulled code p0172 thats it check engine light goes on and off

Replace the IAC valve (idle air control).

Its mounted to the throttle body and cost around 35 bucks for the part. These are real common to get carbon buildup on the tip of the valve and it wont close completely. You can try and clean it before replacing it but I recommend just replacing it.

Below are diagrams showing the location and what the valve looks like.
