Hi, I'm Max and new to the forum. The wife and I are on a road trip and just enjoying all the scenery. I also git the best mpg since I've bought my truck. One question I have is, how difficult is it to change out the glow plugs? My dummy light came on.
Before you go changing out glow plugs, try moving the connector on the plug - twisting, push/pull, etc. Then reset the code and see if it comes back. All this does is ensure the electrical connection is good. I have had two separate glow plugs pop a code, I did this and the code never returned. The truck starts just fine, even in winter.
