- 1994 Ford Explorer XLT
I am troubleshooting some starting issues and while checking vacuum lines/hoses, I came across this opening on the left side of the engine towards the back of the engine bay. Does anyone know what it is for? Should it be connected to something or have a cap on it? If a cap, any idea what size? I don't think I have noticed it before. I have a '94 Ford Explorer XLT.
