A little vague but I'll throw my two cents in. Check for Codes. The plug wires might have tiny cracks in the casing and holding trapped water. Hopefully you didn't soak the alternator.

You washed your engine, and now you are having a miss.

You replaced the plug wifes, and the coil wire.

Can you check the onboard diagnostic codes and see what codes you get, and post them please? See http://www.caddyinfo.com/readingcodes.html

hmm, checking here: http://www.caddyinfo.com/stscodes.html

we can see that AO47 is low A/C refrigerant charge. So that does not show why you are having the misfire.

When you said "I change all 4 coil wire and spark plug wire" you meant you changed all 8 wires + the coil wire I assume. Did you change the plug wires one by one so that you are certain that you did not crosswire any of them? (I managed to do this once after a repair).

How long has the engine been having this miss?

Check the spark plug holes for water. If the ignition wires were not installed to the correct plugs/coils you would get a misfire code (does OBDI throw a misfire code?, it may not). Make sure your ignition wires go from the correct coils to the correct plugs. Make sure your ignition wires are ROUTED correctly, if they are travelling side by side with the injector wires you might be disrupting injector signals, always cross injector wires at 90 degrees. Check to see if you got the injector connectors wet, you can disconnect the connectors (not an easy task by the way), dry them out, and use a small dab of dialectic grease (sorry for the spelling of dialectic, :lol:). Try drying the connectors with a hair dryer (don't tell your wife I said so!)

Check for a cracked plug, improper gapping. In the dark take off the vanity cover and spritz the wires with water, see if you elicit any sparking. What kind of ignition wires and plugs did you use? Did you gap them?

One more thing, if you used dilectic grease on the spark plugs that can cause a misfire, remove it.

Something stupid I did when I changed the wires on my old 87 Deville, I let one of the wires get too close to the manifold, and it burned through the wire, grounding it out, which caused that caddy to miss bad, sounds silly, but maybe that's your problem.

I think this needs to be asked. How well did you wash your engine? I mean did you hose the engine for a long time? Did you use high pressure? What did you use to clean the engine (soap, solvent, etc)? Was the engine hot, warm or cool when you you washed it? Because if you rinsed it lightly and carefully that would be worlds removed from spraying the engine down like a madman. Although I've seen people do it.

Try pulling the coils and blow out the connections underneath with compressed air or if you don't have any usw WD40. Same thing on the 4 plugs to the ICM.
