Engine Performance problem
2002 Chevy Silverado 6 cyl Four Wheel Drive Automatic 130000 miles
I have had the problem for several years now and have just been living with it. It only does this when it gets cold out. Below 50 mainly. When you first crank it up it idles up real high for a few seconds then idles back down and just kinda lopes and will barely run. Once you get the engine warmed up it gets better and once the temperature is up to 200 it runs perfect. I have had a coolant temp sensor and idle air control valve replaced and still no help. Thanks
have the same problem?
