Engine OFF & Iignition ON should not make any difference in the reading, if the key is is in the the ignition enable/start mode, or when attempting to start.I have back probed it and that's where I am getting the 4.1 at no throttle. I will make sure to try again with the engine off ans post my results. Thanks for the input.
