Typical white smoke idle.

[duramax on fire]

Sorry still learning about rates and all. Is it typical to have bad rates at idle with slight haze then all 0 rates with throttle.

40k old injectors but I think they got contaminated when I did head gaskets.

210k miles.

Any thing else cause this problem. Fpr all looked good.

Inj 7 was 2

The balance rates always read 0 with throttle. The ECU can only calculate it at idle.

The balance rates need to be measured with the truck fully up to temperature, and measured twice: once in gear, and once in park. Turn off A/C.

In addition to the balance rate numbers, we need the main fuel rate. You add the balance rate to the main fuel rate to determine the total fuel per cylinder.

If your numbers were in gear, it is barely in spec, IIRC. If that was in park, then at least #1 is out of spec.

Ok thanks a bunch. Did not know about in gear. Didn't read that. I'll recheck in gear now

Ok in drive and fully warm lb7

Fuel rate 11mm3

Inj 7 jumped to 5


Fuel rate at idle is 6. IF I'm reading this scanner right

Shutting 7 down in park did not seem to help smoke. But shutting 1 down seamed to help some.

Ok. Did the pass side injectors today. Took me 3 hours. Got lucky. Didn't drain coolant and didn't have any cups pull out. Balance rate now on 1 is -1.1 and 7 is 1. and the rest are all around .5. Smoke is gone for now hopefully it will stay that away for awhile.

Cool, hopefully the driver's side injectors hold out for you.

I hope. Thanks agian for the help on how to read the rates.
