Thanks for the advice and I have read these before.
The vehicle does not suffer a loss of power when driven. The only time the concern occurs is when it comes to idle.
(Would this be the same??)
I guess really if I fix the air leak in the intake (Rubber hose from
PCV to inlet manifold) the vehicle struggles to idle.
Do I rectify the air leak and then resolve the low idle concern?
Just wish it would learn the throttle position!
