Rough idle when wet
I have noticed that when I go through mud, raining hard driving, or pressure wash underneath, that the engine will start to stumble at idle. no codes are thrown. acceleration is fine and it will not cut off, just rough idle. it has new plugs and wires, and i went all around the engine with a spray bottle trying to see if I could pinpoint the issue. any ideas where to go from here?

What kind of wires? Every time there is moisture in the air my Disco runs terribly, misfires the whole nine until the engine compartment heats up and dries. I replaced the spark plugs and that half solved the problem. I am changing to Magnecor 8mm ignition wires. If you did not install Magnecors then you may want to they seem to be the only wires recommended around here.

Well when I bought my truck 2 years ago I used Duralast wires, they lasted exactly one year. (20,000 miles)
Went bad, replaced under warranty, 3 months later bad again, replaced under warranty, 3 months...bad.
I know have Kingsbourne plug wires, 8mm and so far so good but it has only been a few months so unless you are on a really tight budget I cannot recommend them yet.
They were $35.
Because it is running bad when wet that tells me that it is most likely the plug wires shorting out when wet.
It could also be water inside the ECU.
