I have the Edge with Attitude and my truck smokes a lot at an idle. But it performs fine when driving. White smoke just pours out at an idle. It just started doing this. Any body know why?

Try taking off your edge, but it sounds like injectors. What is the temp outside when it does this? Is the truck warmed up (up to operating temp) when it happens?

Talk to Edge and see if you have the latest version. Edge still advances timing even set at 0 (stock). They might be working on a fix for your problem.

Yeah if it's cold it'll smoke, my 250 smokes a lot when it's cold enough outside but once it's warm unless I pound the pedal and pour black, then I get no smoke of any color
