engine won't stay running

[dware173]

i got a 91 jeep wrangler with a 4.0 liter in it.i washed it the other day and sprayed off the engine real quick cause it was a little muddy.i got in my jeep and started to drive off and then it started sputering and the check engine light came on. i thought it was a little water in the distributor but it was completly dry.when i come to a stop or take my foot off the gas it wants to shut off i have no clue what it is.i checked everything to see if i knocked a sensor loose or something came unhooked but everthing was fine.i was wondering if anyone could give me some advice or even better wants to come by and take a look at it for me.i can't drive and when it will start it won't run for long i have no clue what it is that is wrong. thanks drew

Old plug/coil wires? High voltage loves wet grounds.
Try running it at night and observe the plug wires. The darker the better. My be surprised what you see!
