My truck idles really horribly whenever it's been sitting cold. This has been going on for a little while now. In the past I was able to stop the trouble when I pull off the tube that goes on my egr valve. Now it started back even with the tube off. I got a new egr valve but the problem still exsist. I tried changing the mass air flow sensor, IAC valve, air filter and resetting the codes on computer but nothing helps. I don't have this trouble after the truck has been running about a good 10 to 20 minutes. And it seems like it idles fine if I pull off the connector to the mass air flow sensor. I have no idea what it is. I don't know a whole lot about cars but I know a little to get me by. Can a expert help me out on this one? Would be greatly appreciated.
