Howdy every one, HAPPY MEMORIAL DAY !!!!! Thanks to all you vets for keeping me and mine safe, God Bless you. 07 RKC, 23K miles, TFI, otherwise stock. Bought 2 years ago TODAY with 5K on it. In the past, this machine has had a high idle, for minutes at a time. Shut it off, restart, all is well. Now it has an EXTREMLY low idle, to the point of stalling. It's running on both cylinders, showing no codes. I can tell when it's going to low idle because the exhaust burbules on decel. restart and it is fine at that moment. Runs fine otherwise. I'm stumped, ECM ??? hope not.
