I'm back... at least it's been a few months.

About two weeks ago, my 92 Lesabre started stumbling at idle. I've replaced the air filter (was due for that), spark plugs and wires. The spark plugs were normally worn, and not worn out yet. I use NGK's V-power and never had a problem with them. We had a bit of a dry spell last week, and this week it's back to normal wet Pacific NW weather. It seems the stumbling has gotten worse since it started puring again. The check engine light has not come on.

What's next? Coil packs? I read in a different older thread that a weak battery could cause the same problem? The voltage reads fine (13-14V.) However, I do have some aftermarket wiring hooked up to the battery (via self-resetting fuses) for trailer towing. The Haynes manual also suggested checking for vaccuum leaks?

Any help is as always appreciated. I want to get her to 200k and beyond!
