| ISX poor fuel economy 2010 Pete 386 380,000 2007 ISX. Purchased used at 330,000. Average around 5 mpg and seems to lack power. I got high exhaust gas temperature warning. Two shops looked at it one wanted to put new turbo on it other shop had no idea. Did egr tune-up, doser, and had dpf cleaned. It was a real mess and the egr valve was stuck. Replaced egr valve and cleaned and replaced sensors as described in video. Installed a boost gauge and while under load can get 35 to 40 lbs of boost. I drive 70 mile round trip to ethanol plant running 60 mph. Seems like every trip for 5 to 10 minutes it blows white smoke with odor. I guess it is regen. I am wondering what I need to do next to make this truck run better. I do not have insight software and not sure how to get it without spending a fortune. Any help would be great. | |||

| RE: ISX poor fuel economy is it the original engine in the truck?.. or a replacement. Your post was not very clear. Was it the engine purchased used?.. or the whole truck? and if the engine was replaced, what are the ser# (the ESN#) of the old engine and new engine? .. and what program does it have in it?. These are all very important things that need to be verified if the engine was replaced. User's Signature: ->: What I post is just my own thoughts and Opinions! --- I AM Full Of S__T!. | |||

An inline-6 adapter kit off e-bay or obd2.com is where a lot of people get it. User's Signature: ->: What I post is just my own thoughts and Opinions! --- I AM Full Of S__T!. | |||
