I have a 9182 sprotscoach motorhome with a GM 454 ci engine that wants to run ALL of the time. I cannot get it to shut off with the keys!!! I replaced the entire ignition switch and also the solonoid on the starter and i still have to choke it off or starve it for gas to get the engine shut down. Any ideas of how to correct my problems will be appreciated. Thanks to each of you in advance. Please e-mail me as soon as possible as we are headed back to Idaho in 2 more days.
