My 2007 V8 has been acting a little funny lately when its cold. This morning it seems it was almost hesitating with a slightly erratic idle from 750-500rpm. Decided to check the Scangauge and found there are constant pending codes that start with C, like C2900 C29A0 C2600. And when I say constant I mean like every couple seconds it throws another pending code. I can't do anything with these because there isn't an actual check engine light but driving any distance there might be hundreds of pending codes.
If these are constant pending codes I'm thinking its for something that is constantly running like a fuel pump maybe. Weird thing is, once everything is warm, the hesitation/slightly erratic idle goes away and it runs fine. Truck has 225k miles on it. Checked vacuum lines and it doesn't seem like any popped off. Any ideas??
