I can't seem to get my car to idle properly: Some days it purrs like a cat, other days it stumbles like a drunk. Car does fine on acceleration and usually does when I've driven 10 miles it'll do fine at a light, but thats with it in "D", not "P" or "N". Generally it sounds much better in Drive than in anything else.

 

Anyway, I have a new performance coil, a new PCV, a new fuel filter (though after letting it almost run dry a couple times in a row it might have gunk from the tank in it), new plugs, new cap, new rotor, Chevron fuel, new performance wires, THE FRIGGIN WORKS.

 

Whats going on?
