there was a post in the 4th gen that sounds like my issue but im not sure how similar the engines are, but anyway here is whats happening i will get in the car start it, it will run fine. until i stop and get out, when i restart it the idle will be fine most of the time, it will misfire but no codes yet but when i start driving within 20 feet it is fine, then if i shut it off it will jump to 1200rpms then back to about 500 then bounce like drop go up until it sits at the normal rpms? what the heck is with my car, im almost convinced its a coil again but it goes away and i dont have time to test it when it happens anyone have thoughts on this? i just did seafoam about 2 days ago
