How to check injectors?
I'm a newbie and am looking for some help. I'm not mechanical, so explain it to me like you would to your two year old! hahaha Anyways, I've been trying to get better fuel economy. Oh I have a 99 F-250 SD w/ 7.3 and 104k on it.
I'm just really frustrated because many of the people that I talk to that have the same truck are getting much better mpg than I am. On a trip unloaded and driving nice, I got 14 mpg... On my last trip pulling my boat, I got 10.5 mpg. I realize that I'm not driving a escort here but most are telling me that I should be getting 18 to 20 empty and 15 or so pulling. I don't know if people are BSing me or what?
My truck has the following things done to it. Superchips programmer, k and n cold air intake and aftermarket 4" exhaust. Also running synthetic and fuel supplements. 285 tires and stock is 265 if that matters and no lift. 4x4 and crew cab. Thats it!
I am wondering if I am having a injector problem because on my trip pulling my boat, I went back to stock on the forst part of the trip. It seemed like I did not have alot of power, especially going up not very steep or long hills. The truck would down shift like a gas truck when I was going up hills and I am only pulling for sure less than 5,000 lbs. Even when I'm running stock this truck shouldn't be like this. This is my first diesel so I have nothing to compare it to. Does this sound like an injector issue or any other ideas or suggestions would be greatly appreciated!!! How about checking the injectors. Can this be done with a scan machine or computer or does the motor need to be taken apart and actually look at them? Thanks
