2007 Cadillac CTS 3.6 (Luxury Package)
So for a while now, my CTS has started up with a rattling sound.. for like a year now I want to say. I didn’t think of it until I got an OBD II Scanner to read the codes and I feel like I got the “Code of Death” for my CTS (P0008). When I drive it now, whenever I let off now my RPMs like to drop to 1K, then I hear backfire before it raises back up. It’s even happened when I was cruising at 55 MPH and I thought the engine was gonna stall out. Lowkey worried about the engines current condition and scared to drive it now. Any advice that you guys can give?
