Well, every fall / winter the 97 mark idles funky. A very loopy idle, dropping and raising a few hundred rpms, sometimes stalling, etc. It will happen unless the engine is at full operating temp. I've replaced the IAC twice (it's from Autozone... =/) and little to no difference.
Now, the valve covers slowly leak oil into the spark plug galleys, so I am going to replace the gaskets and plugs and clean it out in there to start out with but I could use other advice if it isnt that.
The car has new Coils and a new IAC with relatively new Motorcraft iridiums. (about 20K on em)
What else could cause a bad idle when the car is cold? IMRC's? DPFE? EGR? Clogged Cats? I could use a little input. Let the diagnosis begin!!!!! :fart
