My sidekick (93) idles REALLY rough.  It also blows a smoke at startup.  I have done some fiddleing around adn I think the injector on my #3 (third from the front) cylinder is junk.  Here is why.  I Pulled the plug wires one at a time and the only one that didn't make the idle worse when it was off was the #3.  I pulled the plug and it was soaked with fuel.  I switched the plug with another cylinder and the plug worked fine in the other cylinder.  I switched the plug wire with another cylinder and it worked fine.  So not the plug or the wire.  I pulled the distributor cap (5 months old) and there didn't seem to be anything wrong there.  So with it all put back together when I just let it sit and idle the idle gets rougher and rougher until it starts to put out a substantial white cloud of unburnt fuel.  So I pulled the wire from the injector.  I am still getting the rough idle (obviously) and the smoke (and stink) of the unburnt fuel isn't as bad but still happens.  So here is the question: is the #3 injector bad or do I have another problem?

Thanks.
