Check your EGR valve. If it needs it clean it. Not free since you will probably need to get new gaskets for when you put it back. A good look will also help you have some idea about health of your EGR system.
With the mileage you quoted I think I would spend more time on preventive maintenance mods and not mess with a tuner. I have a 4" exhaust, with no restrictions, and really like it. It might affect your mileage because it sounds so good you will be more apt to keep your foot on the skinny...
Since I have joined the sight I have done more searching and reading than posting. However, the main reason I am not on as much is I moved to an area that essentially has no internet. I considered HughesNet but some of the folks in my area, that have it, say it is not very good and they are...
Thanks for all the input. My mechanic suggested doing all 8 at once and I know that is probably the way to go but I have had a few things come up that prevent me from doing that right now. I have thought about selling it. Not because of problems but I just do not get to drive it much and I...
Are there any advantages to changing all of the injectors at once? I have a couple that are becoming suspect but would like to just change them unless there is a good, valid reason to change them all.
I was having a similar problem...but very sporadically. Truck would also lug from time to time just never in a consistent manner. I changed the filters and it ran like a scalded ape...for a while. Then everything started over again. Long story short I had to have the cam shaft sensor...
Thanks for the input guys. You are echoing what I thought but I wanted to get some input from the experts. I will change the filters after I burn this tank of fuel...it was about time to do that anyway.
My father-in-law borrowed my truck, to haul some hay equipment, and he noticed the fuel level was getting low so he pulled it up next to his tank an filled it up with off road diesel. Aside from it being illegal to drive it on the highway is this going to cause me problems in engine operation...
Just my $.02 but drive one for a while first. They have lot of power without any mods. I have done a couple of things to mine: 1. blue spring upgrade, 2. 4" turboback exhaust with no cat or muffler and it has about all the power I need. I do not tow a 5th wheel or camper but I haul a lot of...
I have never used the cruise control while hauling, but I cannot believe that alone would cause the "wrench" light illuminate. Dave is right many dealers and part stores will scan your truck and give you the results. The downside is sometimes the result can be pretty vauge. Did you notice any...
I only use the tow/haul feature if I am pulling a really heavy load i.e. 30' gooseneck loaded down with round bales, etc. Most lighter loads tend to be handled pretty well without using it. I have used it a few times while hauling cattle with my bumper pull and it stayed in the lower gears a...
