Should I be worried?

[Duramax52513]

Sometimes at idle I have a lite gray haze that comes out of my stack, but I've only noticed it when it's hot out. Is this a problem I should be worried about?
Please help me out, this is my first duramax and none of buddies have duramax's

Have you injector balance rates checked. usually that is a sign that they are starting to go on a LB7.

 

[Duramax52513]

That's what I figured, what should the balance rates read if there good and bad

+or- .4 at idle in gear or less is ok.

And make sure your on the stock tune when checking while truck is hot

 

[Duramax52513]

I don't have a tune on it yet so that should be easy to do haha but still check them hot right

Ya. And I believe Watson meant + or - 4.0 in park and + or - 6.0 in drive.

 

[LWATSON]

I ment in gear, that's what I've always been told but that doesn't mean I was given the correct info.

I more so meant on the .4 you had not in gear or park:hug:
