The main aim of this process is to increase the amount of air flow through the engine startup and adjust its timing accordingly. PCM (Powertrain control module) will store the code P050B if it does not match the RPM’s request.
What does code P050B mean?
Part of the control module’s logic in the this process is to increase the amount of air flowing through the engine on startup and adjust the engine’s timing accordingly. If the engine speed does not match the PCM’s RPM request, the PCM will store code P050B.
What does P050D code mean?
Cold Start Rough Idle
What does OBD-II fault code P050D mean? OBD-II Code Decreased engine performance is defined as a Cold Start Rough Idle. The engine control module (PCM) monitors misfires on initial startup. When the PCM detects a misfire on startup, the PCM will set code P050D.

Zitat von Youtube: If the ignition coil is covered with engine oil or stains. Simply clean it with a wd-40 cleaner otherwise replace the damaged ignition coil with a new.
What causes rough idle cold start?
An overly rich air mixture to fuel mixture is what causes a rough idle in both cases. In cold temperatures, the computer uses a richer combustion mixture than usual to heat your engine. Fuel mixture runs well in both cases, and idle will be difficult.
