My s3c is running very lean. Each time when I change the mixture of fuel and air to more fuel, it adjusts itself after a while.
After an investigation my garage told me that the engine had a very low 'subpressure' (don't know the exact english word)...confused
Can this mix up my engine management and cause the lean mixture, and therefore the bogging down at low power?
What is the effect of a low 'subpressure' on an engines functioning anyhow?
