Ok, so I bought my camaro about a month ago and now its acting up. Its a 2010 SS with roughly 70,xxx on it. Aside from a cold air intake and flowmaster mufflers, I have good reason to believe the rest is stock. Ive concluded using my laptop (OBDwiz) that the MAP sensor was crazy wrong, though it wasnt throwing a code for that. Replacing the MAP sensor made a difference, but its still throwing the code. It also seems that damn active fuel management kicks on early and stays on longer when the MIL is on. It seems like first thing in the morning the MIL wont come on, but rather when I come home in the evening itll light up. The fuel pressure seems to be in spec, as well as the TPS, MAF and O2s. I'm at a bit of a loss. And would love to delete that AFM
