That is about the time it takes a component to heat up again and show a problem,it seems you have isolated the problem good just make sure the components around the Ic are not getting cool too because it might be one of the,if you are sure nothing else is getting cool check the solder conections on the chip and if they are solid just replace the IC.Is a good place to start.

Why is there an intermittent loud hissing noise from engine compartment, usually just after startup?


You just hear it better if you lower the roof or open your windows. It could just be your air intake. Unless your rpm`s are really racing to above 2500 or it is at high idle for a long time, you shouldn't kick it down. When it is cold your choke is helping to warm it up quickly. Nothing is really working properly until it reaches normal operating temperature. Let it warm up. If you are still concerned, listen under the hood for better perspective and when in doubt, take it to a professional.
