1998 Ram Van 1500 is "sputtering" with the air conditioning on
HELP! My 1998 Ram van 1500 is sputtering or hickuping for about a fraction of a second while I'm traveling down the road with the air conditioning on. It happens seemingly at random and doesn't matter what the speed is, it's happened at 30 Mph and at freeway speeds. At first I thought that it was doing it all the but after replacing the plugs, plug wires, PCV, and cleaning the IAC, I noticed that it was only happening when the air conditioning was on.
It's a 1998 Ram 1500 Mark III conversion with the 3.9l V6 and a 3 spd transmission.
Thanks for any help!

The only idea I can come up with, is that the wiring that goes to the compressor clutch is bare somewhere and randomly touching ground. This would cause a momentary drop in electrical power, which in turn would drop out power to the ignition. Not being a solid short and only being momentary, would also explain the fact that no fuses have blown...yet.

I still haven't looked at the wires yet....darn work thing getting in the way!
I don't think that the compressor is freezing up, as it doesn't happen when I'm sitting at idle with the AC on. It only happens when I'm traveling down the road. That's why I originally thought that it was a fuel problem under load, until I realized that it wasn't doing it w/o the AC.
Who knows, I've been wrong before. It will definately be something to check if I can't find a wiring problem. Any Idea how to test the compressor?
