Default finally got the engine to idle normal

so started off
1 MAF & TB cleaning when i first got the vehicle
2 new spark plugs 107K never been done
started getting bad mpg
3 oxygen sensors. do them both at the same time its right there
4 Camshaft Actuator Solenoid and camshaft position sensor because why the hell not
5 purge valve and last but not least
6 purge valve canister solenoid

here is it taken apart because i wonder what the hell a $30 dollar part looks like inside



here is the reason i believe it was still leaking even tho i didn't have a code. not sure but this is open and its been replaced before on my H3


then here is where my idle is sitting at stop signs. not sure if its correct but i am assuming because the h3 is keeping it there it is correct. No more shaking!!!!!!!
