Well, I was giving the car a good cleaning today, and thought I would give the engine a shampoo while I was at it. Was real careful. Covered the alternator. No high pressure spray on any electrical components. Well, engine came out looking great, but it idled like crap afterwards and hesitated under power. The drive was a short one (5 minutes), and it didn't clear itself up during it. Hoping it will dry out overnight and run ok in the AM. At least it will be light then and I can see what is going on. Will take this to the appropriate mechanical forum if I find an issue.
Read lots of success stories here about engine cleaning. Couple of problems too. I guess mine falls into the latter category.....

u cleaned it while the car was on right?

Hmmm. I guess I missed that part....

I never cover anything, and never run it during...


it will dry out and be fine.

Thanks Peter
Will sleep better tonight!

I agree with Peter, I've never covered anything but usually use an air hose to dry it a bit quicker either way if you had issues then maybe your ignition wires may be in need of replacement.

Agreed.
I use a leaf blower, more air less pressure

just replaced the wires yesterday, so they should not be a problem, unless I left one loose.

It doesn't hurt to recheck the ignition wires since one may have either come loose, or may not have been on properly and water in advertanly entered some electrical source.

Does it run any better now that it'* more dry?

when i washed my engine i took out an ICM and had 2 coils that were cracked and did horrible once they got water in them.
