Odd idle after car wash

[GraphitE21]

Any insight as to why the idle on my 81 e21 m10 would get funky after a car wash (and the rare Cali rainy day)?

Thanks!

did you use a steam cleaner or high pressure cleaner? Maybe some moisture in ignition system like distributor ....
see the TI service bulletin on my website http://twrite.org/shogunnew/check/alerts.html

@shogun No, just a regular hand car wash with standard hose.

It's probably #6 seal here on realoem.
Letting water run down near the ignition distributer. ?
