NLPRacing Posted July 25, 2016 Share Posted July 25, 2016 I had a bad heater hose on my 2007 Expedition that was leaking right on top of a coil. It would make it short out and give me a code that the coil was bad. Once I replaced the hoses, no more trouble. 1 Quote Link to comment Share on other sites More sharing options...
