Re: Idle Issue

It’s the weather!
Cooler moist air is the problem.
It creates a colder intake.
Cold fuel vapour inside the intake reverts back to a liquid. The liquid gas puddles in the intake. Some vapour gets to the chamber but is too lean to support god combustion. It runs rough.
Cure is a heat soak. Usually when it starts to run rough if you shut it off for 5 minutes and wait for the hot air in the lifter valley to heat the intake then you’ll be good to go.
