So i thought it would be great to clean my engine up with the pressure washer......wrong. i wrecked one coil pack and after my computer was reset, my car sometimes idol low. like 400, 350 for only a second and then it serges to 800 or 1000. i have no idea. it's been a week since they reset the computer. does anybody have any ideas?
 
Yes, pull the coil packs and shop vac out the water in the wells.

Also, before reinstalling coil packs be sure to condition the rubber parts on them with silicone spray and use silicone dielectric grease on the springs where they connect to the spark plugs.

Also, while you are in there you might consider changing your plugs or at least inspecting them. If you replace them use Motorcraft AGSF-32C gapped at .54 (assuming you are pretty much stock).
