My wife has a 2011 Focus SE. We are preparing to move back to America, and I was cleaning her car up for shipping as it has to be really damn clean for them accept it. I sprayed the engine bay down with simple green, and then rinsed with a medium pressure hose setting. The next day after parking it in a single car garage she complained of the garage smelling of gas. I checked fuel cap, inspected some hoses, and looked for signs of a liquid fuel leak. No issues were apparent. Next day I go out to garage to see if it smells of gas and it's pretty strong smell. The car is not throwing an engine code which I find odd because an evap emissions issue should cause and engine code. I need to get it fixed ASAP. Any thoughts?
