Yep I got the codes, CHeck engine light, and reduced performance displayed. I thought it was the MAF sensor cleaned it, no change. Started to look closer and low and behold the cold air duct from air filter to throttle body right at the flexible corrugated plastic, was failing. I touched it and it crumbled. I did a temporary duct tape repair. Reset the code, drove 20 miles and no check engine light Ive ordered a replacement duct. Sometime its just that simple.
