Situation got worse. On cold start the car bucks and shakes and throw all kinds of codes. 02 , misfires and map sensor circuit codes. I already threw money on most of the parts in the past month(maf, map, plugs, coils and O2)
So after I drive the car a few miles, it starts not doing all of the above but goes back to my original idle hunting issue.
Battery at 12.5v with car off and 13.5-13.8v car on.
Also wiggled around the harness to the throttle and to the ignition system and stil idle hunts.
