'02 Chevy Silverado. 61K miles. On cold mornings when I first start it, it runs like crap. If I give it some gas, the idle smooths out completely. When I let off, it goes back to running like poo. Once it warms up, it runs fine. Now, the "Service Engine Soon" light is on. This sounds like an EGR valve issue. What do you guys think?
