I have a 2012 Traverse that needed the throttle and valves cleaned (getting misfires lately), and I've seen good reviews for the GDI/intake valve cleaner. Couldn't find CRC, but Seafoam had good reviews as well, so went with it. Followed the instructions and came back from the hot soak to find the car won't start. Won't even turn over. It had a couple weak attempts and starting, but ultimately nothing. Not the battery as everything lights up no problem. Not sure about the starter, but it seems like it wants to start. Took the plugs out, and they're pretty well cooked. 2 of them had some oil as well. While I have yet to get new plugs, I'm wondering if I should expect new plugs to solve the problem, or is there something else going on. Seems to me that I'd at least expect it to turn over decently if spark was the only thing missing.
