What does p050d mean on a cold start?
A rough idle, or poor idle quality under cold start conditions, could be an indicator of a more serious problem. A code P050D should be addressed at your earliest convenience and considered severe.
Why does my GMC p050d run rough at Cold Start?
Condition: A vehicle may have a concern of DTC P050D setting along with a P0300 after a cold start up. White smoke and/or coolant odor may come from exhaust for an extended period of time at cold start as well. It may also Run rough when warm, slight knock, no codes setting. Cause: Coolant getting into the cylinders.
What causes a GM Silverado to get a p050d code?
The casting for the heads was not done properly in some cases and it results in coolant leaking into the cylinder and throwing the P050D code along with a rough cold start. As you pointed out though, it could just be a bad injector.
When to use a p050d rough idle code?
If, under cold start conditions the PCM detects a rough idle that cannot be stabilized within the programmed parameters, a code P050D will be stored and a malfunction indicator lamp (MIL) may be illuminated. Multiple ignition cycles (with a failure) may be required for MIL illumination. Idle Air Control (IAC) Valve:

What does the code p050d mean on a Chevy?
Cause: Coolant getting into the cylinders. If there is coolant in the cylinder, the cylinder head will need to be replaced. The cost to diagnose the P050D CHEVROLET code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.
