Hey all, can anyone give me some leads as to why on cold startup my truck fires beautifully but then idles at 450rpm and feels like its about to stall (normal idle is 650 - 750)?
I have turned up the idle screw but it only makes a difference when warm and it idles and drives perfect when warm.
Is there a temperature sensor or something that should up the idle when the engine is cold?
Truck fires up perfectly with a tiny puff of black. Oil sensor tells me cold idle pressure is at 80psi which drops back to 20psi when engine is warm.
Any ideas appreciated! Thanks
