Michael Yount said:Mine cranks right up hot or cold; you can drive away immediately without it stalling or bucking - one of the benefits of efi that's working properly. How long it takes to warm up depends on the type of driving. But I'd say two to three minutes and it starts to show coolant temp movement. I try to limit revs to about 1/3-1/2 of redline when the oil's cold (oil pressure on mine hits 60-65 IMMEDIATELY upon start up cold) so I don't take it over about 2000-2500 rpm until the oil temp hits at least 160F. That can take 10-15 minutes of around town driving. It can take as much as 20-25 minutes if it's less than 40F outside, and I crank it cold and head straight for the Interstate - which is only about 3 minutes from my house.
As many have alluded to, the car warms up MUCH more quickly being driven than it does idling. There's no load at idle, and relatively speaking, the engine just doesn't give off much heat.
20-25 minutes? wow...that is a long time to get warm...
Mine starts up better "pure" cold than it does when it is warm...my hot-start problem is getting better for some reason...?
