My XM began running rough while cold and was down on power. Based on my readings of this forum I bypassed the preheater.
Very easy job; trace fuel lines to find preheater, remove fuel lines and replace with single new line that bypasses the preheater.
Car now runs fine from cold and power is back.
So a quick thanks to all those who took the time to document what they have done so that I could identify and fix with ease.
