    Fuel Balance Rates

    There was actually black grim on the tip. I see where the o ring keeps it out, but the tip had a bunch on it on a few. Still trying to figure out how to clean out the hole so it does not go in while installing the new injectors.

    Fuel Balance Rates

    Ok so ran the cleaner thru and very little improvement removed the edge no improvment so working on changing the injectors, and got them all out. 5 had a black grunge on them, and thinking I got bad gas in norther AZ (in the middle of nowhere my mistake) and thinking this is the problem. Now...

    Fuel Balance Rates

    Got to love one of those days so while trying to do the injector cleaning had the wrong size fuel line toll, had to drive to town (15 min each way). Got home still could not get the line off, then went to SEARS (a little closer) to get different fuel line tool. Got home after some work got the...

    Fuel Balance Rates

    Well today had a friend that knows Duramax and told me to unplug my edge and the engine ran smoother. Also found that there was an update and did that, and then plugged the edge back in. Now I am at just two sitting at a +6 and another at -6. Still going to clean the injectors and run it a few...

    Will do that going to run the cleaner this weekend, not sure how enough trash would get in the rail, but will check. Just changed the filter two weeks ago hoping that was the issue. Also looking at doing the CAT filter mod, figure a better filter would be good, and cheaper never hurts.

    Fuel Balance Rates

    Was wondering if clogged, which I am hoping the injector cleaner process may help with or pressure regulator? Just don't want to spend the money on 8 injectors, not fix the problem and possible mess up the new injectors.

    Fuel Balance Rates

    I understand why the rate goes up, but would that be the injectors that are bad causing the fluctuation, or the pressure regulator. But while driving and towing the truck seems to run fin and the mileage is normal.

    Fuel Balance Rates

    So am I to understand this just confirm the injectors? Sorry but I don't understand the jumping when I put in drive, but his is where it smokes more and runs rougher. Sorry new to Diesel.

    Fuel Balance Rates

    I am using an EDGE EFI, so I was not as worried about location as 5 were out of tolerance so I figured I was looking at replacing them all if the injector cleaning did not work. Cold they were all fine, but warm is when everything went bad. I am not sure how to check the fuel rate unless I get...

    Fuel Balance Rates

    With the GM standard being at idle +-4 these look way out, so as I understand this is from a standard fuel flow rate. Now if I change these I am thinking I should replace them all instead of just a few.

    Fuel Balance Rates

    I have a 2005 and have been having some white smoke only when warm in drive at stop lights. I checked the balance rates and got some really off numbers, I know supposed to be +-4 in park and 6 in drive, but have one side all positive and the other all negative. 1 -7 2 6.5 3-6.9 4 4.3 5...
