Some background: I recently resurrected my stang to daily driven status. about 3 weeks ago I washed the engine bay, and even though I was careful to cover the distributor and coil, the engine developed an idle problem. Basically, you crank it on, revs to about 2K RPM (normal), and then it drops momentarily to about 500 RPM and sputters like it wants to die. Then it comes back up and settles about 8K, but it stays pretty uneven, like I have a bigger cam (engine is stock, just a CAI).
A lot of people suggested I change the cap and rotor, and since it was over due for it anyways, I changed cap, rotor, plug wires and plugs. I used MSD cap&rotor, FMS wires, and Autolite platinum plugs.
Well, the problem went away for a couple of days, but yesterday it started doing the same thing. The old plugs didn't look bad, but the 1 to 4 plugs were a little rusty (I guess normal since they were about 2 years old).
Any help would be greatly appreciated.
