Hey Allen,
I have a flashing SES light after I first start the truck and it idles for a minute or two. I starts flashing then I will hold the RPM's to about 1000 and it will soon go away. What do you think it is? I was also wondering if you programmed the fan setup into my pcm? I will be helping Andrew do his fans this week and want to do the same to mine. Thanks for your help.
