Old tired injectors will also cause different fuel flow to each cylinder, with the result that some run rich and some run very lean to get the correct mixture at idle, so it runs rough. Smooths out as speed increases and the amoutn of fuel running through the injectors incraseas. New injectors are in the works for the TE, once I get a few bucks ahead somehow.
