01Duramax with new injectors p0089 code after starting and smokes like a chimney

Mechanic's Assistant: How many miles are on the car? Have you been losing oil or coolant?

260k neither i replaced injectors due to bad balance rates and haze under throttle now it lopes and smokes worse

Mechanic's Assistant: Are you fixing your Silverado yourself? What have you tried so far?

Did you do the programming after replacing the injectors?

Did you follow the correct installation procedure for the injectors, cleanliness, and correct torque values?

I didn't do the programming
Chevy Mechanic: Gary, ASE Certified Technician replied 2 months ago

Ok, at best now, you need a Chevy tech to do the injector programming.

Do you have a Chevy dealer nearby?

sir!
Chevy Mechanic: Gary, ASE Certified Technician replied 2 months ago

I would contact the dealer, and have the truck towed there.

Don't run the engine anymore until they look at.

I thought they didn't start doing the programming until the 06 models, I replaced the injectors with new bosch stock injectors.
Chevy Mechanic: Gary, ASE Certified Technician replied 2 months ago

I think they do have a "flow rate" number for Tech2 programming.

The injectors fall into groups of flow rates.

The P0089 also needs to be reset afterwards.

I can reset and it clears until I hit the accelerator and that kills the engine and blows white smoke out the exhaust.
Chevy Mechanic: Gary, ASE Certified Technician replied 2 months ago

Is that the same as the original issue, white smoke?

It had improper balance rates and hazed at an idle but now it's worse.
Chevy Mechanic: Gary, ASE Certified Technician replied 2 months ago

Can you look on the top of your old injectors to see if they have a programming code written on there, like a 2 digit alpha numeric code, ie A3?

Ok.

I would contact your dealer as a heads up to them as well.

Gary, I looked at the tops of the injectors and they all have numbers on the tops, none of which are the same
Chevy Mechanic: Gary, ASE Certified Technician replied 2 months ago

That will be the programming number.

I've seen some 20 characters long.

I am reviewing your request and will post in a moment.

So there is no programming on these injectors, that was not an option until 2007.

So on yours, now with this what is the balancing rates on each injector?

Ask Your Own Chevy Question
Customer reply replied 2 months ago
I put new injectors in and some of them were coming out to 7.5. I can't go past idle without blowing white smoke and killing the engine.
Chevy Mechanic: GM Tech (Cam), Chevy Technician replied 2 months ago

Was there an extreme the other way, a - 7 or greater?

Ask Your Own Chevy Question
Customer reply replied 2 months ago
I will have to start it up again, and check for diesel fuel in oil
Customer reply replied 2 months ago
Will I be ok to run it long enough to get balance rates? and how accurate will the test be without the truck being up to operating temp?
Chevy Mechanic: GM Tech (Cam), Chevy Technician replied 2 months ago
It’ll give me a good idea. I’m suspicious that some junk in debris fell down into the inlet of the injector from the back of the fuel line when you remove them.
