Rough idle

Always use quality gas, they call it top tier in many parts of the country.

I dont think its just how it is. Some days it runs smooth others it will be smooth then i come to a stop and it has a bad vibration.. steering wheel all over the place because of it. Ive notice every now and then when i come to a stop or brake hard the rpms drop below 500, or the rpms wont drop smooth it will be choppy. Like maybe a throttle postion sensor but i think you have to replace the throttle body to replace that not sure. Correct me if im wrong. It didnt do this when i bought it had 107k on it then now its at 143k.

Its never had check engine light or stored codes except for the vvt solenoid and the thermostat... found out about the intake gaskets by checking the bolts, and most of them backed out on there own. So i figured that was what was causing the rough idle so i changed them, and it got better of course but maybe twice a day or so it does this... so one day i turned my ac on let it kick in and turned it off and it smoothed out.
